Welded Steel Pipe

A672/A672M Standard Specification for Electrofusion Welded Steel Pipe for Medium Temperature and High Pressure Service. The main difference between ASTM A672 and A106 is that A106 seamless steel pipe is a seamless carbon steel pipe used for high-pressure applications, while A672 electrofusion welded pipe is an electrofusion welded carbon steel pipe used for high-pressure applications at moderate temperatures. What is the minimum wall thickness for ASTM A672 straight seam

API 5L spiral welded pipe is a spiral welded steel pipe that meets the American Petroleum Institute (API) standard API 5L and is commonly used in transmission pipeline systems in the oil and gas industry. API 5L spiral steel tube is a commonly used pipe material in the oil and gas industry. It has excellent mechanical properties, corrosion resistance and high strength. It is made of low carbon steel, high strength steel, corrosion resistant steel and other materials, and

ASTM A671 EFW welded carbon steel pipe is a carbon structural steel pipe manufactured using the electrofusion welding process. This kind of steel pipe is mainly used in high-temperature and high-pressure transportation systems, such as boilers, petrochemicals, thermal pipe networks and other fields. ASTM A671 electrofusion welded straight seam steel pipe is a steel pipe for normal and low temperature use. There are multiple brands and grades below. The grades are: CA55, CB60,

ASTM A252 pipe can be manufactured by a variety of production processes, including seamless or welded methods. Welded pipes are usually produced by methods such as resistance welding (ERW), submerged arc welding (SAW) or double submerged arc welding (DSAW). Material composition: ASTM A252 piling pipe is usually made of carbon steel. Requirements for chemical composition are specified in the standard to ensure required properties such as strength and durability. grade: ASTM

ASME SA53-TypeS/B is a general-purpose seamless steel pipe with tensile strength ≥ 415 (MPa) and yield strength ≥ 240 (MPa); executive standard: ASTM A 53. ASTM A 53 welded pipe is suitable for pressure piping systems, pipeline pipes and general purpose pipes with temperatures below 350°C. ASME SA53 Class B ERW pipe is available in a wide range of sizes and can be customized to suit the user's needs. Common size parameters include: usually ranging from smaller sizes (such as
