Either x52 pipe in seamless or welded (ERW, LSAW), the pressure ratings, tensile strength and yield strength is the same. In case the working conditions require bigger pressure, we will have to increase the wall thickness of the steel pipes, or use higher grade in API 5L. Test Requirements:
ASTM A252 Pipe Pile Specifications (In seamless & welded The most common pipe piling material is ASTM A252 Grade 3 pipe, this pipe grade could be made in seamless or welded, which in most situations are requested in welded type because of the large diameters pipe pile required. A252 Grade 3 has better strength which tensile in 455 Mpa (66,000 psi), and yield strength 310 Mpa (45,000 psi).
Testing conducted on all of the samples were Charpy impact, yield strength, ultimate tensile strength, elongation, hardness, and grain structure. Pipe Manufacturing Process The most commonly used pipe manufacturing method for steel water pipe is spiral welding coil steel in a continuous process (See Figure 2). The process starts with steel
Quality Inspection Standard of Spiral Steel Pipe before Sep 01, 2020 · The quality inspection standard of spiral steel pipe before delivery. Strength inspection of pressure vessel test stress of hydrostatic test shall be in accordance with the corresponding steel strip standard. 60% of the minimum yield (Q235 is 235Mpa) is selected. Stabilization time:D<508 test pressure holding time is no less than 5
Specified Minimum Yield Strength - an overview Maurice Stewart, in Surface Production Operations, 2016. 220.127.116.11 Miters. In systems intended to operate at a hoop stress of more than 20% of the specified minimum yield strength of the pipe, miter bends are prohibited. Miter bends not exceeding 12-1/2° may be used in systems operated at a hoop stress of 20% or less of the specified minimum yield strength of the pipe, and the minimum distance
Pipe having other dimensions may be furnished provided such pipe complies with all other requirements of this specification and the grades of steel of the manufactured pipes. The pipe is intended for conveying liquid, gas, or vapor.

Technical - Racetech SteelUltimate is what the material actually is. i.e a Racetech 350 tube can be around either 400 MPA or as high as 750 MPA, depending on the quality and processes the material goes through. Elongation:The ratio of yield and ultimate (actual) tensile. This ultimately determines the malleability of a metal.
With the increase of pipe diameter, steel grade increase, resulting in greater the ductile fracture tip steady expansion trend. According to test the relevant research institutions in the United States, shown that the spiral welded pipe and Longitudinal is the same as a level, but the spiral welded pipe has a high impact toughness.Steel Line Pipe Suppliers in Australia Irrigation Pipe Structural Steel Hollow Sections, Grade 350MPa:API5L:ERW/Spiral Pressure Pipe:API5LB/C350:Pressure/Structure Pipe (minimum yield strength 350MPa) AS1396:Steel Water Bore Casing:A252 Grade 2:Structural Grade Pipe Grade 250MPa:A252 Grade 3:Structural Grade Pipe Grade 350MPa
