ASTM A312 Stainless Steel Pipe Suppliers in Delhi – PS Steel
Stainless steel seamless pipes are a vast area of piping materials available in various compositions, sizes, and types. We at PS Steel are manufacturers and suppliers of all types of stainless steel pipes. PS Steel has been in this business for many years, and we manufacture various types of stainless steel pipes. SS pipes are available in different types and sizes.
Types of Stainless Steel Pipes

Stainless steel ERW pipes are electrically resistance welded, while other types such as electric fusion welded and cold drawn pipes are also available. Different standards are available, such as ASME B36.19 stainless steel pipes. B36.19 is for wrought stainless steel.
At PS Steel, stainless steel seamless pipes are available in round, oval, and rectangular shapes in Schedule 10/40/60 thicknesses according to pressure ratings and dimensions as per ANSI/ASME B36.19. Schedules are useful in calculating the pressure containment of each pipe type. You can also check our SS Pipe Size Chart for reference.
ASME SA312 stainless steel pipes are used in applications where strength is paramount. Stainless steel Schedule 10 pipes have relatively lower pressure classes. At PS Steel, we also manufacture different grades. Our ASTM A312 stainless steel pipes, such as A312 TP304, are applicable for high-temperature services. We manufacture ANSI B36.19 stainless steel pipes in all grades.
Although SS round pipes are the most commonly used, we also manufacture SS oval pipes and SS rectangular pipes for specialized purposes. Our SS rectangular pipes can also be used in structural applications. We supply stainless steel pipes for various industries, from domestic and low-cost applications to aeronautical, chemical, marine, and petrochemical industries. You can also explore stainless steel pipe wall thickness for more technical details. Please compare our prices with other stainless steel pipe manufacturers in India or China before placing your order.
