The ASTM A312 specification covers seamless and welded austenitic stainless steel pipes used for high temperature and/or corrosive service (the most common grades are 304/304L and 316/316L). The A790 specification covers seamless duplex and super duplex pipes UNS S32205/31803 and UNS S32750/32760 (special SS grade with a mixed ferritic/austenitic microstructure).

ELECTRIC RESISTANCE WELD PIPE (ERW). Cold finished pipe made by a series of operations in which the flat rolled material is cold shaped into tubular form and welded at the seam by the application of pressure and heat. The heat is generated at the seam by the resistance to the flow of electric current applied through electrical contacts
ASTM A312 A312M ASME SA312 TP304 TP304L TP316 TP316L is the standard including seamless and welded stainless pipes. ASTM A312 A312M ASME SA312 Covers seamless, straight-seam welded, and heavily cold worked welded austenitic stainless-steel pipe intended for high-temperature and general corrosive service.
Seamless SS pipes are available in the size range 1/8″ thru 24″, welded stainless pipes are manufactured in the range 2″ thru 36″ (ASTM A312, ASTM A358, i.e. electric-fusion-welded austenitic chromium-nickel stainless steel pipe, or as rolled).
ASTM A312 TP 321 Stainless Steel Seamless Pipe/ Tube is a common austenitic 18/8 stainless steel alloy, with the addition of titanium, making it a good choice in high temperature environments of up to 900° C. 321 stainless steel seamless pipe/ tube has good welding and forming capabilities and is widely used in operating temperature environments in excess of 500° C. Stainless steel 321H, commonly
316 / 316L stainless steel plates are part of the austenitic family of stainless steel and is the most widely used varieties of stainless plate. 316 grades contain a higher level of Nickel than 304 giving it an improved corrosion resistance over 304 grades. 316/316L plate is a good option for marine applications due to a good atmospheric corrosion resistance. 316L is a low carbon modification

About 30% of these are stainless steel pipes, 1% are steel pipes, and 1% are plastic tubes. A wide variety of sus tubing options are available to you, such as api, astm, and jis. You can also choose from iso, sgs, and ce. As well as from oil pipe, structure pipe, and hydraulic pipe.
304 stainless steel plate grades have good welding characteristics and post weld annealing is not normally required to restore performance. 304 SS plates have excellent corrosion resistance in a variety of different media. Typical specifications for 304 and 304L ss plates are ASTM A-240, ASME SA
ASTM's steel standards are instrumental in classifying, evaluating, and specifying the material, chemical, mechanical, and metallurgical properties of the different types of steels, which are primarily used in the production of mechanical components, industrial parts, and construction elements, as well as other accessories related to them.
