Liner Hanger Manufacturers Supplying UAE Operators

If you are trying to find the best liner hanger manufacturers supplying UAE operators, you can shortlist any one of them on three checkable things: its current API Composite List status, its published lead times, and a working UAE documentation and vendor-registration route.

Supply in this category means engineered-to-order tools shipped from the manufacturer's plant against a purchase order, with export paperwork and, for an operator's approved-vendor list, a local-content or registration step. You can verify a maker's standing yourself on the API Composite List before you ever make contact.

Maximus OIGA Private Limited supplies its SpectraMax liner hangers this way from Vadodara, with no local UAE entity claimed unless it is stated. The quick checklist below sets out what to confirm for any liner hanger supplier.

What does a UAE buyer need to know before shortlisting a liner hanger manufacturer

A UAE liner hanger shortlist should be built on five checkable things, not a brand ranking. Judge every liner hanger supplier on the same five points and the list ranks itself against your well and your procurement rules.

• Register status: is the manufacturer currently listed on the API Composite List, and does the certificate scope cover liner hanger systems, checked on a date you record. An ISO 14310 or ISO 9001 certificate is not the same as an API licence.
• Origin and plant: where the tool is actually made and shipped from.
• Product coverage: which liner hanger types the manufacturer builds, so one vendor can cover more of your well.
• Published lead times: most liner hanger manufacturers do not publish them, so a maker that states a lead time is easier to plan around.
• UAE route: export documentation and the ADNOC In-Country Value (ICV) or vendor-registration step that lets a foreign maker supply an operator here.

One more control sits under all five: to rule out a counterfeit or a lapsed licence, verify the licence on the API Composite List and check the API Fraud Alerts page before you buy. The shortlist itself follows.

Which liner hanger manufacturers can supply UAE operators, and how do they compare

The manufacturers below are compared on the same five checkable criteria, with each register fact carrying the date it was checked. The table names no winner. It is a starting shortlist for a UAE buyer, and every row points you back to a public source you can check yourself. Register status was last checked on the dates shown, so re-run each check on the day you rely on it.

If you are one of the manufacturers listed and believe an entry is out of date, write to us with the correction and we will re-check the public register and update the row. The table is only as good as your ability to check it, so the next section shows how to run the register check yourself in a few minutes.

How do you verify a liner hanger manufacturer for the UAE, step by step

Any liner hanger manufacturer's API status is verifiable in minutes by searching the API Composite List at the API website and confirming the certificate scope covers liner hangers. Here is the check, in order.

1. Search the register. Go to the API Composite List at mycerts.api.org and search by company name or certificate number. Record the date of your search.
2. Read the certificate scope. A licence is specific. Confirm the certificate scope names the product you are buying, a liner hanger or a liner top packer, not just the company name. A maker can hold a licence for one product and not another.
3. Know what each mark means. API Q1 is the petroleum industry's quality-management standard, audited to the oil and gas sector's own requirements; a general ISO 9001 certificate is not an API licence and does not replace one. API 11D1 and ISO 14310 cover packer design, validation and V-grade sealing, so a liner top packer can be qualified to 11D1 while the hanger body is not. Match the mark to the part.
4. Treat API 19LH with care. API 19LH is not an API Monogram specification, so a claim of a "19LH monogram" cannot be verified on the Composite List. Ask what the number actually refers to.
5. Screen for a counterfeit. Before you buy, check the API Fraud Alerts page for the manufacturer or the product. The register tells you what is licensed; the Fraud Alerts page tells you what has been flagged.

Run this same check on every maker on your shortlist, including Maximus OIGA Private Limited. Once a manufacturer checks out, the next question is when it can actually deliver.

What lead times should a UAE operator expect for liner hangers

Liner hanger lead times into the UAE fall into published bands, roughly 1 to 4 weeks, 4 to 12 weeks, and 8 to 16 weeks or more, depending on product class and configuration. Maximus OIGA Private Limited publishes these bands for its SpectraMax line, which is unusual in this category: no competitor in the researched set publishes lead times at all, so a band on the page is itself the difference.

• 1 to 4 weeks: standard product classes and accessories close to a stock position.
• 4 to 12 weeks: configured tools that need machining or assembly to your well.
• 8 to 16 weeks or more: fully engineered-to-order strings and non-standard configurations.

Delivery timing depends on the product class you specify and the current stock position, so a firm date comes with the quotation, not before it. On price, this is a quotation business: the page carries no number, because cost turns on the configuration, the materials and the documentation you need. The quotation states the price and the committed date together. Getting the tool made is only half the job; getting it into the UAE with the right paperwork is the other half.

What export documentation ships with a liner hanger into the UAE

A liner hanger order into the UAE ships with a documentation pack: material test reports, an inspection and test plan, heat traceability, test and verification reports, and shipping and origin documents. This pack is what makes an engineered-to-order tool auditable, which is what an operator's QA function asks for. Ask any manufacturer for these by name.

• Material test report (MTR): the mill certificate for the steel and alloys, tying each part to its material grade.
• Inspection and test plan (ITP): the plan that states what was checked, when, and to what acceptance limit.
• Heat traceability: the heat numbers that trace each component back to its melt.
• Test and verification reports: the results from the tool's own testing before it ships.
• Certificate of origin and shipping documents: what customs and your freight forwarder need.

Product ratings and V-grades belong in this pack, not in a headline. Rather than claim a grade on a web page, the tool's test and verification report and the datasheet supplied at quotation carry the evidence, checked against the exact part you are buying. At Maximus OIGA Private Limited, the in-house test cell at the Manjusar/Savli plant verifies liner hanger performance before shipment, which is why that verification report can travel with the order. Documentation gets the tool through customs; a vendor number gets you onto the operator's approved list.

What local-content and vendor-registration steps does the UAE require

Supplying an ADNOC-group operator usually requires vendor registration and an In-Country Value (ICV) score, which a foreign manufacturer meets through the ICV programme and, often, a local agent or partner. The two steps are separate and both matter.

• Local content: the ADNOC In-Country Value (ICV) programme scores suppliers on how much of their spend stays in the UAE economy, and that score is weighted when an ADNOC-group operator awards work. A supplier earns an ICV certificate through an approved auditor.
• Vendor registration: operators keep approved-vendor lists, and a manufacturer has to be registered before it can be awarded a purchase order. A foreign maker often registers through a UAE agent or partner that holds the local presence.

For a liner hanger manufacturer outside the UAE, these two steps are the practical route onto an operator's list. Whether a given manufacturer already holds an ICV score or a registration is a question to put to that manufacturer directly; this page describes the route, it does not assert any maker's current status. With the route clear, here is what can actually be supplied.

Which liner hanger product families are available into the UAE

Maximus OIGA Private Limited manufactures liner hangers in hydraulic, mechanical and rotating setting types from one plant, under the Quartus and SpectraMax names. Naming the setting type matters, because it decides how the hanger is run and set in your well.

• Quartus QHH: a hydraulic-set liner hanger, set with applied pressure.
• Quartus MSL: a mechanical-set liner hanger, set with a J-slot mechanism.
• Quartus RLH: a rotating liner hanger, for running liners that need rotation to reach depth.
• Quartus Liberty: a single or dual cone liner hanger.
• Magnus QLH: a combined liner hanger and packer.
• Max Dual Cone Hydraulic Liner Hanger: a dual cone hydraulic type.

The SpectraMax accessories complete the string: a liner top packer, a polished bore receptacle, a tie-back packer, setting sleeves, running tools including RH and hydraulic-release types, landing collars and wiper plugs. Buying hydraulic, mechanical and rotating types from one manufacturer lets a buyer standardise across well types without adding a second vendor. Specific pressure and temperature envelopes and V-grades are not stated here; the product datasheet and the quotation carry the verified ratings for the exact model. Made and documented is not the same as delivered, so here is how it reaches the UAE.

How are liner hangers shipped from the plant to the UAE, and on what terms

Liner hangers for the UAE ship from the Manjusar/Savli plant at Vadodara to UAE ports such as Jebel Ali, on the incoterm the buyer specifies. The shipping route is short: from the plant in Gujarat the tools move by sea to a UAE port, most often Jebel Ali or Khalifa Port, and then through customs with the documentation pack.

• FOB: the maker delivers to the loading port; you take over the sea freight and import.
• CIF: the maker covers freight and insurance to the UAE port; you handle import from there.
• DAP: the maker delivers to a named place in the UAE; you handle import clearance.

Which one suits you depends on your own freight and customs setup, so name your preferred incoterm and delivery port in the quotation request. Being honest about the route means being honest about its limits, which the next section sets out.

What does Maximus OIGA Private Limited not have in the UAE

Maximus OIGA Private Limited does not operate a local entity, office, agent, stocking point or field-service crew in the UAE unless stated otherwise; it supplies as a manufacturer, ex-plant from Vadodara. That is worth saying plainly, because a shortlist is only useful if it tells you what a supplier cannot do as clearly as what it can.

So there is no local office and no walk-in support in the UAE, no in-country agent unless one is named to you, no local stock you can draw against at short notice, and no field-service crew on call at the rig. Installation and field support are handled as manufactured equipment with documentation and remote engineering support, not as a rig-site service with the maker's own people on the derrick floor.

If any of that changes, for example a named UAE agent or a stocking arrangement, it will be stated to you directly rather than implied. You do not have to take any of this on trust, so the next section shows how to check it yourself.

How can you verify any of this yourself

Every claim on this page is checkable against public registers and published standards, listed here with their sources. Use them to verify any manufacturer, this one included.

• API Composite List (mycerts.api.org): who holds a current API licence and for which product scope.
• API Fraud Alerts: products and companies the API has flagged.
• ISO 14310 and API 11D1: the published standards for packer and liner-top-packer design, validation and V-grade sealing, so you can read what a grade actually means.
• ADNOC In-Country Value (ICV) programme: the UAE local-content scheme and its approved auditors.
• MCA company register (India): the incorporation record for an India-registered manufacturer, including Maximus OIGA Private Limited, if you want to confirm the corporate entity you are buying from.

Record the date beside every register check, because a register can change. If you are a manufacturer named on this page and think a register fact is out of date, tell us the correction and we will re-check the source and update it. Below are the questions UAE buyers ask most often.

Frequently asked questions

These are the questions UAE buyers raise most. No UAE-specific People-Also-Ask set was returned for this query when the search results were checked on 09/16/2026, so these are drawn from the in-market liner hanger questions and from the concern buyers state most often.

How do I check that a liner hanger is genuinely API-licensed?

Search the API Composite List by company name or certificate number to verify the licence, confirm the certificate scope covers liner hangers, and check the API Fraud Alerts page. An ISO 9001 certificate is not an API licence. Record the date you checked, because the register changes.

Does Maximus OIGA Private Limited have an office in the UAE?

No local office is claimed. Maximus OIGA Private Limited supplies as a manufacturer, ex-plant from Vadodara, unless a UAE agent or arrangement is named to you directly. Treat any unstated local presence as something to confirm, not to assume.

What lead time should I expect for a liner hanger into the UAE?

Published bands run roughly 1 to 4 weeks, 4 to 12 weeks, and 8 to 16 weeks or more, depending on the product class and configuration. A firm date comes with the quotation.

What is the difference between a liner hanger and a casing hanger?

A liner hanger supports a liner, a string of casing that does not reach surface, by hanging it off the inside of the casing already in the well. A casing hanger sits in the wellhead and supports a full casing string run to surface. Different tool, different place in the well.

What is the difference between a liner and casing?

Casing runs from the wellhead down; a liner is a shorter string hung below existing casing and does not reach surface. A liner saves steel and rig time when a full string is not needed.

Who are the major downhole tool manufacturers?

The manufacturers commonly named for liner hangers include SLB, Halliburton, Baker Hughes, Weatherford, NOV, Innovex International and Welltec, alongside specialist makers such as Maximus OIGA Private Limited. Judge any of them on the five criteria in this guide, not on name recognition.
