Looking for stainless steel compression tube fittings in Sri Lanka? Samvay supplies double ferrule instrumentation tube fittings in SS 316, duplex, super duplex and nickel alloys, certified to EN 10204 3.1.
From our machining base in Ahmedabad we supply instrumentation tube fittings to Sri Lanka, a market shaped by refining at Sapugaskanda and power. Colombo is only a few days by sea from Mumbai, so Sri Lankan plants get quick, reliable supply.
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 Sri Lanka the typical service is tropical humidity and marine 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 Sri Lanka
Service conditions in Sri Lanka usually mean tropical humidity and marine air. These are the grades we most often supply for that duty.
| Recommended grade | Why it suits Sri Lanka |
|---|---|
| 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 316H or alloy steel F11 and F22 | High temperature steam service, supplied with IBR documentation where required |

Frequently asked questions
Can Samvay supply instrumentation tube fittings to sites around Colombo?
Yes. We ship by sea from Mundra or Nhava Sheva to Colombo in about 3 to 5 days. Regular consignments reach Colombo, Hambantota and Kerawalapitiya, 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 Sri Lanka?
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 Sri Lanka?
Orders for Sri Lanka are supplied to ASME B31.3 and EN 10204 3.1. 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 Sri Lanka we still recommend using ferrules and nuts from one supplier on each joint.
