Trusted & Recognized name in the stainless steel industry!
Manufacturer of ASTM A312 Austenitic Stainless Steel 304H Pipes, ASME SA312 SS TP304H Seamless Piping
Austenitic Stainless Steel TP304H Seamless Pipes
Alloy 304 stainless steel is one of the most commonly specified austenitic grades for industrial applications. Both 304 and 304H grades are selected where strength and corrosion resistance are required at varying temperature conditions. 304 stainless steel pipes, along with flanges, plates, and fittings, are used across a wide range of process and structural applications. ASTM A312 304H Stainless Steel Seamless Pipe is produced using controlled manufacturing methods to meet specified mechanical and chemical requirements.
A manufacturing process of the pipes-
Pipe production typically begins with pickling, followed by end preparation. The material then undergoes lubrication and is processed through cold rolling or cold drawing operations, followed by degreasing. Heat treatment is applied to achieve the required properties, after which straightening and final pickling are carried out. Pipes are then cut to standard or project-specific lengths. Each pipe is subjected to inspection and testing, including dimensional checks, eddy current testing, and ultrasonic testing to ensure compliance with applicable standards. After inspection, the pipes are marked, packed, and prepared for dispatch.
The manufacturing process for ASTM A312 304H Stainless Steel Seamless Pipe is carried out using established production methods to ensure consistency in quality and performance across supplied material.
