The weld of spiral steel pipe is longer than that of straight seam steel pipe. If the pipe length is L, the weld length is L/cos(θ). Most of the defects of steel pipes are concentrated in the weld and heat-affected zone. The long weld means that the probability of defects is high. This is the main r

Spiral steel pipes are a type of long steel with spiral seams, which are mainly used in the following aspects:1. Transporting liquids or gases: Spiral steel pipes can not only transport tap water, natural gas, and other media at room temperature, but also high-temperature and high-pressure thermal t

First, introduction to epoxy powder anti-corrosion steel pipe.An epoxy powder anti-corrosion steel pipe is a pipe that uses a special process to tightly combine polymer materials such as polyethylene (PE) or epoxy resin (EP) with the surface of the steel pipe through hot dipping or spraying. This pi

Stainless steel capillary tubes can be used in industries such as medical equipment, precision instruments, and fluid transportation. These industries have high requirements for the dimensional accuracy, material performance, and cleanliness of metal pipes. However, due to the relatively small inner

Submerged arc welded straight seam steel pipe, as a commonly used steel pipe product, has many advantages and a wide range of applications.First, the characteristics of submerged arc welded straight seam steel pipe.Submerged arc welded straight seam steel pipe is a pipe made by pre-bending and cold-

1. Operating Pressure and Temperature:- Determine the maximum operating pressure and temperature of the boiler.- Refer to boiler manufacturer specifications and ASME codes (e.g., ASME SA-106 for seamless tubes and ASME SA-379 for welded tubes) for pressure-temperature ratings of different materials.

1. ASTM A588 - This standard covers high-strength low-alloy structural shapes, plates, and bars, including seamless square tubes, for use in applications requiring structural steel with improved atmospheric corrosion resistance.2. ASTM A36 - This standard covers carbon structural shapes, plates, and

ASTM A312 is a specification published by the American Society for Testing and Materials (ASTM) that covers seamless and welded stainless steel pipe for use in high-temperature and high-pressure applications. This specification is commonly used for piping in the oil and gas industry, as well as in c

Flanges are an important part of connecting pipelines and equipment, and flanges of different specifications have different sizes. Choosing the wrong flange size will lead to problems such as loose pipe connections, leakage or damage. Therefore, several factors need to be considered when selecting a

1. Material Specifications: Fire-fighting pipe fittings are typically made from metals such as carbon steel, stainless steel, or brass, depending on the application. The material must meet the appropriate ASTM specifications for the type of fitting, ensuring it can withstand the pressure and tempera
