An ISO 9001, ISO 14001, OHSAS 18001 Certified Company & GOVT. OF INDIA RECOGNIZED EXPORT HOUSE, PED Certified, Pacific Steel Overseas is India’s most trusted manufacturer of Carbon Steel Flanges, Carbon Steel Pipe Flange and High Pressure Carbon Steel Flange. All our Carbon Steel Flanges are manufactured with tested raw materials and are supplied with NABL approved lab test reports. On demand, we can also provide, Hydro Testing Reports, Non Destructive Test Reports, or Destructive Test Reports. Carbon Steel Flanges are manufactured in accordance with ASTM, DIN and ISO specifications & 3.1 certified material.

Our Carbon Steel flanges, collars and rings are forged or seamless rolled. The manufacturing process includes an adequate heat treatment and the examination of technological and mechanical properties. The final finishing happens on appropriate CNC machines, as well as on conventional lathe, depending on the size. The screw holes are generally drilled to ensure a flat surface for srews. A Carbon Steel Flange, a collar or a seamless ring is produced to order by the corresponding flange standards DIN, EN, ANSI, GOST, JIS and other international norms and standards or according to customer specifications.

Pacific Steel Overseas is a specialized manufacturer in the production of Carbon Steel flanges with customized dimensions as per our customer drawing. Especially in the area of lapped (loose) flanges (DIN 2641/2642 / EN1092-1 Typ 02), flanges for soldering or welding (plate / plain flange) (DIN 2573/2576 / EN1092-1 Typ 01) and blind flanges (DIN 2527 / EN1092-1 Typ 05) price reductions could be realized by using reduced – but the demands sufficient – blade thicknesses instead of the standard.

We manufacture Carbon Steel flanges dimensions according to the complete standards range from DN10 up to DN2400, respectively 1/8” up to 60”. All other dimensions beyond this range on request.
