Buyers in Kolkata use Samvay high pressure pipe fittings across refining and petrochemicals at Haldia, steel plants in the eastern belt and thermal power, all machined and tested at our Ahmedabad works. Eastern India's steel and power plants rely on Kolkata stockists, and we supply them with alloy steel and IBR certified fittings.
High pressure pipe fittings join small bore pipe and tube on hydraulic, chemical injection and process lines where ordinary fittings would leak or fatigue, using forged bodies machined from certified bar stock. In Kolkata the typical service is humid delta climate and high temperature steam service in power plants, 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 Kolkata
Service conditions in Kolkata usually mean humid delta climate and high temperature steam service in power plants. These are the grades we most often supply for that duty.
| Recommended grade | Why it suits Kolkata |
|---|---|
| Super duplex 2507 or S32760 | High chloride air and seawater, where PREN above 40 resists pitting and crevice corrosion |
| SS 316H or alloy steel F11 and F22 | High temperature steam service, supplied with IBR documentation where required |
| Duplex 2205 or Inconel 625 to NACE MR0175 | Sour hydrocarbon service, where hardness control and sulphide stress cracking resistance are required |

Frequently asked questions
Which material grade do you recommend for projects in Kolkata?
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 316H or alloy steel F11 and F22 is a cost effective alternative. Share your process data and we will confirm the grade before quoting.
How do high pressure pipe fittings reach Kolkata from India?
Yes. We ship by road dispatch from our Ahmedabad works in 4 to 5 days. Regular consignments reach Haldia, Howrah, Kalyani and Syama Prasad Mookerjee Port, 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 Kolkata?
Orders for Kolkata are supplied to IBR approval, ASME B31.1 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.
Which sizes and pressure ratings can you supply?
Our high pressure pipe fittings are available from 1/8 inch to 2 inch (3 mm to 50 mm), rated at 1000, 3000, 6000 and 10000 psi, with NPT, BSPT and BSPP threads, weld ends or JIC ends. Bodies made from hex are produced to ASTM A276 and items from round bar to ASTM A182, which matters when your specification for Kolkata calls out the bar standard.
