What is a 312 pipe?
ASTM A312 pipe is the general use stainless steel pipe applied in different industries. It covers diameters from 1/8” to 30” and thickness from SCH 10S to SCH 80S. Common use material grades are TP304/304L, TP316/316L.
What does SA 312 mean?
Standard pecification for Seamless and Welded Austenitic Stainless Steel Pipes. Overview. 1.1 This specification covers seamless and straight-seam welded austenitic steel pipe intended for high-temperature and general corrosive service.
What is ASTM A312 Tp304?
A312 Tp304 is an austenitic alloy grade designed with a superior composition of nickel and chromium. The ASTM A312 Tp304 alloy has excellent resistance against corrosive and oxidative media across stress-induced environments. The versatile grade of alloys has outstanding mechanical properties.
What is SA 312 TP 316L?
ASTM A312 Grade TP316 and TP316L refer to the stainless steel 316 and 316L respectively. The prefix “TP” denotes “type” of the stainless steel. TP316 or TP316L pipes may be furnished in seamless or longitudinally welded types with butt welding ends or threaded ends.
Is code for stainless steel pipes?
73041110 – Of stainless steel: Tubes and pipes HS Code and Indian Harmonised System Code.
What does ASTM A312 mean?
ASTM A312. STANDARD SPECIFICATION FOR SEAMLESS, WELDED, AND HEAVILY COLD WORKED AUSTENITIC STAINLESS STEEL PIPES. 1.1 This specification covers seamless, straight-seam welded, and heavily cold worked welded austenitic stainless steel pipe intended for high-temperature and general corrosive service.
Is code 316 stainless steel?
Stainless steel types 1.4401 and 1.4404 are also known as grades 316 and 316L respectively. Grade 316 is an austenitic grade second only to 304 in commercial importance. 316 stainless steel contains an addition of molybdenum that gives it improved corrosion resistance.
Is 300 or 304 stainless steel better?
Type 304 is the most widely used alloy of all stainless steels. 300 Series Stainless steel alloys resist corrosion, maintain their strength at high temperatures and are easy to maintain. 300 series grades are inventoried in in stainless steel plate, sheet, bar, pipe, tube and structural products.
Is stainless steel water piping more durable than copper?
To have a clear understanding of both metals, it is important to look at their upsides and downsides. Durability: Stainless steel is more durable than copper and can withstand harsh conditions. Appearance: Maintains consistent colour throughout lifetime of product.
How to repair stainless steel pipe?

What does A312 tp316/316l mean?
ASTM A312 TP 316 / 316L Stainless Steel Pipes and Tubes is the low carbon version of 316 stainless . With the addition of molybdenum, the steel is popular for use in severe corrosion environments due to the materials immunity from boundary carbide precipitation (sensitisation).
Is seamless steel pipe better choice than welded tube?
Using seamless tubing allows you to avoid the potential for defects and differences in malleability that may be associated with the welded area in welded tubes. Unlike welded tubes, seamless tubes do not require testing for weld integrity. Therefore, seamless tubing is often more suitable for critical applications.
