Carbon Steel Unions
The product is a carbon steel union made from ASTM A105 or A350 LF2 material, supplied in nominal pipe sizes from ½ inch to 4 inch. Each union conforms to ASME B16.11 and ASTM A105 standards and is rated for pressure classes ranging from Class 2000 to Class 6000. The fittings feature male and female threaded ends, allowing flexible installation in a variety of piping systems. They are packaged in fumigated wooden crates or cartons suitable for containerised transport.
Carbon steel unions of this type are standard components in high‑pressure pipelines used across oil & gas, chemical processing and water treatment facilities. The ASTM A105/A350 LF2 grades provide typical tensile strengths of 415 MPa and good weldability, while the pressure class rating ensures suitability for temperatures up to 250 °C. Surface treatment is applied for corrosion resistance, with a standard hot‑dip galvanised coating or a painted finish as required by the buyer.
Industrial buyers such as plant engineers, construction contractors and equipment manufacturers source these unions for reliable, leak‑proof connections. The supplier does not disclose a fixed minimum order quantity, so purchasers should confirm the batch size needed for their project. Trade conditions - including FOB Mumbai, CIF any port, and payment options like L/C or T/T - are negotiated per transaction, and the harbour‑tier verification indicates a basic level of supplier credibility, though recent response activity is not recorded.

Sourcing Carbon Steel Unions from Kalyan Steel Centre - India Import Guide
Verify the supplier’s incorporation documents, the exact ASTM grade of the carbon steel and the pressure class before finalising a purchase. Request a sample or a third‑party test report if the order volume is large or if the application is safety‑critical.
Agree on the Incoterm - commonly FOB Mumbai or CIF any destination port - and confirm payment terms such as an irrevocable L/C or T/T. Clarify the expected lead time for production and any pre‑shipment inspection that the buyer wishes to perform, as the supplier does not publish a standard schedule.
Arrange for a pre‑shipment inspection covering dimensional accuracy, thread fit and coating thickness. Ensure that the shipping documents include the material test certificate, pressure‑class verification and a statement of compliance with ASME B16.11.
