Buyers in Oman use Samvay instrumentation tube fittings across oil and gas production, LNG at Qalhat and refining at Sohar and Duqm, all machined and tested at our Ahmedabad works. Oman's new Duqm refinery and long running fields create steady demand for certified tube fittings and needle valves.
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 Oman the typical service is hot desert and coastal salt air, 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 Oman
Service conditions in Oman usually mean hot desert and coastal salt air. These are the grades we most often supply for that duty.
| Recommended grade | Why it suits Oman |
|---|---|
| Super duplex 2507 or S32760 | High chloride air and seawater, where PREN above 40 resists pitting and crevice corrosion |
| Duplex 2205 or Inconel 625 to NACE MR0175 | Sour hydrocarbon service, where hardness control and sulphide stress cracking resistance are required |
| SS 316L with impact testing | Low temperature and cryogenic duty, with Charpy test results on request |

Frequently asked questions
How do instrumentation tube fittings reach Oman from India?
Yes. We ship by sea from Mundra or Nhava Sheva to Sohar in about 6 to 8 days. Regular consignments reach Sohar, Duqm, Sur and Muscat, and mixed orders of valves, fittings and accessories can be consolidated into one shipment with a single set of documents.
Which material grade do you recommend for projects in Oman?
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, Duplex 2205 or Inconel 625 to NACE MR0175 is a cost effective alternative. Share your process data and we will confirm the grade before quoting.
What certificates come with orders for Oman?
Orders for Oman are supplied to PDO 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 Oman we still recommend using ferrules and nuts from one supplier on each joint.
