I. What material is API5L
1. API5L-B pipeline steel, equivalent to L245 brand Wuyang Iron and steel, L245 belongs to the low alloy series, the price is relatively high, the price of different materials is not the same, mainly used for oil pipelines, natural pipelines, etc., is a low pressure fluid coil pipe, its performance and 20# seamless pipe almost.
2. The material is X52 grade pipeline steel pipe line steel, which is a kind of steel with special requirements used for conveying oil and natural gas pipelines. According to the thickness and subsequent formation, it can be produced by hot continuous rolling mill, furnace rolling mill or medium thick plate mill and formed into large diameter steel pipe by spiral welding or UOE straight seam welding.
3. Seamless or welded steel pipe, the standard is API 5L(pipeline pipe) PSL2 is one of the grades, the other is PSL1 in comparison, PSL2 requirements are higher than PSL1API 5L is the pipeline pipe specification formulated by the American Petroleum Institute, B is one of the pipeline steel grades.
II. API5L standard
1.API5L standard, the number of joints of steel PIPE and PIPE WLD 10" SCH STD API5L ASTM A106 GRB seamless steel pipe in the same section shall not exceed 50% of the number of pipes. Before installation, the pipe shed shall sweep and clean the holes of drill or high pressure air to remove the scum in the holes. Ensure that the aperture (the aperture shall not be less than 127cm) meets the requirements and prevents hole plugging.
2. Cr:≤025 Nickel Ni:≤030 Copper Cu:≤025 Mechanical properties: Tensile strength of sigma b (MPa) : 560 (57) or higher yield strength sigma s (MPa) : 335 (34) or higher elongation delta (%) : acuity reduction of area of 18 bits (%) : 45 or higher impact energy Akv (J) : 55 or higher impact toughness values of alpha kv (J/cm2).
3.API 5L standard covers the production requirements of pipeline steel, especially for tensile strength, yield strength, room temperature impact toughness, elongation at break, etc. According to the types of pipeline steel,API 5L is divided into general steel pipe and special steel pipe, among which general steel pipe is divided into ordinary steel pipe and high strength steel pipe,API 5L standard also covers the production process requirements of pipeline steel.
III, what is the API5Lgrb material
1. API 5LGRB is seamless or welded steel pipe, the standard is API 5L(petroleum pipeline pipe), PSL2 is one of the levels, the other level is PSL1 in comparison, PSL2 requirements are higher than PSL1API 5L is the pipeline pipe specification developed by the American Petroleum Institute, B is a kind of pipeline steel grade.
2.ASME SA517, ASTM A517 pressure vessel Quenched and tempered high strength alloy steel plate ASME SA517/SA517M standard includes: SA517GrA, SA517GrB, SA517GrH, SA517GrS, SA517GrP, SA517GrF, SA517GrE, SA517GrQ; ASTM A517/A517M standard includes: A517GrA,.
3. Supply API 5L PSL2 standard spiral steel pipe GrB-X70 Outer diameter 219-3650 mm Hello, we have been producing spiral pipe for 24 years, we hope to have the opportunity to cooperate with you.
