API 5L X46 PSL1 ERW 11.8m Length 6 Inch Carbon Steel Pipe ASME B36.10

API 5L X46 PSL1 ERW Pipe, 6 inch, 11.8 meters, SCH.STD, ASME B36.10 Standard, Black Surface.

Overview
Since the 1930s, with the rapid development of high quality strip continuous rolling production and the progress of welding and inspection technology, the quality of weld seam has been continuously improved, and the variety specifications of welded steel pipe have been increasing day by day, and seamless steel pipe has been replaced in more and more fields. The welded steel pipe is divided into straight seam welded pipe and spiral welded pipe according to the form of weld. Classification according to production methods: process classification-arc welding pipe, resistance welding pipe ,(high frequency, low frequency) gas welding pipe, furnace welding pipe.
The small-caliber welded pipe adopts straight seam welding, while the large-caliber welded pipe adopts spiral welding; it is divided into circular welded pipe and special-shaped (square, rectangular, etc.) welded pipe according to the shape of the end of the steel pipe; it is divided into mineral fluid conveying welded steel pipe, low pressure fluid conveying galvanized welded steel pipe, belt conveyor roller welded steel pipe and so on. According to the current national standard specification size table, according to the outer diameter * wall thickness from small to large order.

Product standards
Welding pipe commonly used material is: Q235A,Q235C,Q235B,16Mn,20#,Q345,L245,L290,X42,X46,X60,X80,0Cr13,1Cr17,00Cr19Ni11,1Cr18Ni9,0Cr18Ni11Nb and so on.
The blank used in welded steel pipe is steel plate or strip steel, which is divided into furnace welding pipe, welding (resistance welding) pipe and automatic arc welding pipe because of its different welding technology. Because of its different welding form, it can be divided into straight seam welding pipe and spiral welding pipe. Because its end shape is divided into circular welded pipe and irregular (square, flat, etc.) welded pipe. The welded pipe is divided into the following varieties because of its different material and use:
GB/T3091-2008( welded steel pipe for low pressure fluid transportation): mainly used to transport water, gas, air, oil and heating hot water or steam and other generally lower pressure fluids and other use pipes. Its representative material is: Q235A grade steel.
GB/T14291-2006( mine fluid conveying welded steel pipe): mainly used for mine air pressure, drainage, shaft gas welding steel pipe. Its representative material Q235A,B grade steel.
Stainless steel welded steel pipe for GB/T12770-2002( mechanical structure): mainly used for machinery, automobile, bicycle, furniture, hotel and hotel decoration and other mechanical parts and structural parts. Its representative material 0 Cr13,1Cr17,00Cr19Ni11,1Cr18Ni9,0Cr18Ni11Nb and so on.
GB/T12771-1991( fluid conveying stainless steel welded steel pipe): mainly used to transport low pressure corrosive medium. Representative material is 0 Cr13,0Cr19Ni9,00Cr19Ni11,00Cr17,0Cr18Ni11Nb,0017Cr17Ni14Mo2 etc.
Other, decorative welded stainless steel pipe (GB/T 18705-2002), architectural decoration stainless steel welded pipe (JG/T 3030-1995), and heat exchanger welded steel pipe (YB4103-2000).
