ASTM A53 is standard specification for pipe, steel, black and hot dipped, zinc-coated, welded and seamless. This specification covers seamless and welded black and hot-dipped galvanized steel pipe.
This specification covers the following types and grades:
1 Type F—Furnace-butt-welded, continuous welded Grade A.
2 Type E—Electric-resistance-welded, Grades A and B,
3 Type S—Seamless, Grades A and B.
Type F is not intended for flanging.
If Type S or Type E is required for close coiling or cold bending, Grade A is the preferred grade; however, this is not intended to prohibit the cold bending of Grade B pipe.
Type E is furnished either non expanded or cold expanded at the option of the manufacturer.
ASTM A53 pipe (also referred to as ASME SA53 pipe) is intended for mechanical and pressure applications and is also acceptable for ordinary uses in steam, water, gas and air lines. It is suitable for welding and for forming operations involving coiling, bending, and flanging, subject to certain qualifications.
My company production line adopts the most advanced spiral welding process technology, namely Two Step Production Process. The pipes are firstly formed into a pipe body and continuous tack-welded at high speed. In the second process step the pipes are subsequently finally submerged arc welded and that gives a higher quality weld compared with other SAWH production method. This process will eliminate the tensile stress of weld seam during pipe forming and submerged arc welding. It also effectively improves stability of the welded joints and productivity. These products are widely used in onshore oil and gas pipe.
