Carbon & Stainless Steel Tube & Pipe SupplierAs a steel pipe supplier, Nansteel Manufacturing Co., provide any standards & grades steel products, API 5L GR.B or X45-80, API 5CT, ASTM A53 GR.B, ASTM A106 GR.B, ASTM A213, ASTM A312, ASTM A333, ASTM A335, ASTM A519, ASTM A179, ASTM A192,ASTM A672, DIN 1629, DIN 21391, EN 10210, EN 10219 etc. Out diameter of sizes is from 21.3mm to 3500mm, thickcess is from
1. Tube end should be vertical to the pipe central axis after cutting. There is no burr on the pipe end. 2. According to agreement, we use steel pipes with the wall thickness of 3.2 mm to do polishing. 3. The angle of side channel is 30°. The surface thickness of steel pipe end is1.6 mm (±0.8 mm).
DIN 2448 Seamless Steel Tubes DIN 2448 ST35/ ST 52/ ST DIN 2448 ST35 Seamless Pipe supplier. DIN 2448 is a standard that gives specifications for seamless carbon steel pipes and tubes including conventional masses per unit length, dimensions, couplings in addition to weights.

The weld of spiral steel tube is the spiral angle, so the synthetic stress at the spiral weld is the main stress.Under the same working pressure, the wall thickness of spiral pipe with the same diameter can be reduced than that of straight seam welded pipe.According to the above characteristics, when the spiral steel pipe bursts, because the
Difference between ERW, SSAW, LSAW - Alloy Pipe, Tubes Difference between ERW, SSAW, LSAW. Steel pipe for pipe technology, can be divided into (SML), mainly as the Oilfield internal transportation pipeline and small-diameter high-pressure natural gas pipeline, used for a small number of long-distance gas pipeline, the vast majority of long-distance pipeline with Direct seam high frequency (ERW), spiral submerged arc (SSAW), LSAW three (LSAW).
Difference between ERW, SSAW, LSAW - Alloy Pipe, Tubes Spiral submerged arc (SSAW) is its forward direction and forming tube centerline hose reel molding angle (adjustable), side molding edge welding and weld them into a spiral, the advantage of the same specification to produce a variety of diameter sizes steel pipe, raw materials to adapt to a wider range, the weld can avoid the main stress force
The SSAW pipe diameter range is from 20 inch to 100 inch, 406 mm to 2540 mm.The advantage part is we can get the different diameter of SSAW pipes with the same size of the steel strip, there is a wide application for the raw material steel strip, and welding seam should avoid the primary stress, good performances to bear the stress.Leading Manufacturer for Ssaw Line Pipes - Seamless Leading Manufacturer for Ssaw Line Pipes - Seamless Structures Tube Rise Steel Detail:tandard:ASTM A519,ASTM A513,BS 6323,DN 1629,DN2391,EN 10305-1,JIS G3441.
