From our machining base in Ahmedabad we supply instrumentation tube fittings to Qatar, a market shaped by LNG production and gas to liquids. Ras Laffan is the heart of global LNG supply, and its expansion projects need large quantities of instrumentation fittings.
Instrumentation tube fittings use a front and back ferrule to grip and seal tubing without welding, giving a leak tight, vibration resistant joint that can be remade many times during maintenance. In Qatar the typical service is gas processing service in hot, humid coastal conditions, so grade selection and documentation matter as much as price. Every order ships with heat traceable material and a test record.

Choosing the right grade in Qatar
Service conditions in Qatar usually mean gas processing service in hot, humid coastal conditions. These are the grades we most often supply for that duty.
| Recommended grade | Why it suits Qatar |
|---|---|
| Super duplex 2507 or S32760 | High chloride air and seawater, where PREN above 40 resists pitting and crevice corrosion |
| SS 316 or brass | Natural and fuel gas trains, with soft or metal seats chosen for the gas quality |
| SS 316H or alloy steel F11 and F22 | High temperature steam service, supplied with IBR documentation where required |

Frequently asked questions
Which material grade do you recommend for projects in Qatar?
For high chloride air and seawater, where PREN above 40 resists pitting and crevice corrosion, we usually recommend Super duplex 2507 or S32760. Where conditions are milder, SS 316 or brass is a cost effective alternative. Share your process data and we will confirm the grade before quoting.
Can Samvay supply instrumentation tube fittings to sites around Ras Laffan?
Yes. We ship by sea from Mundra or Nhava Sheva to Hamad Port in about 6 to 8 days. Regular consignments reach Ras Laffan, Mesaieed and Dukhan, and mixed orders of valves, fittings and accessories can be consolidated into one shipment with a single set of documents.
What certificates come with orders for Qatar?
Orders for Qatar are supplied to QatarEnergy material specifications, NACE MR0175 and ASME B31.3. Every part is heat marked and traceable to its mill certificate, and third party inspection by the agency of your choice can be arranged before dispatch.
Are your tube fittings interchangeable with other double ferrule brands?
Our double ferrule design follows the established geometry used by the leading instrument fitting brands, and the fittings are available from 1/8 inch to 2 inch and 3 mm to 50 mm, rated up to 10000 psi depending on tube wall, with male, female, union, reducer and bulkhead configurations. For mixed brand installations on sites in Qatar we still recommend using ferrules and nuts from one supplier on each joint.
