As an important building material, steel pipes are widely used in all walks of life. When purchasing steel pipes, different application scenarios have different requirements for steel pipe wall thickness. Among them, 120 steel pipe wall thickness is a common parameter.First, the significance and app

Plastic coated steel pipe DN15 is a pipe widely used in construction, industry, and civil fields. It has excellent corrosion resistance, high strength, and good sealing, and is widely used to transport various media such as liquids, gases, and solids.1. Characteristics of plastic coated steel pipe D

1. Basic introduction of square and rectangular steel pipesSquare and rectangular steel pipes are common steel profiles with a rectangular or square cross-sectional shape. It is made of hot-rolled or cold-drawn steel plates through welding, cold-bending, or hot-rolling processes. Square and rectangu

1. The uses of large-diameter stainless steel pipes can be divided into oil well pipes (casing, oil pipes drill pipes, etc.), pipeline pipes, boiler pipes, mechanical structure pipes, hydraulic support pipes, gas cylinder pipes, geological pipes, chemical pipes (high-pressure fertilizer pipes, petro

Plastic-coated steel pipe not only has the advantages of high strength, easy connection, and water flow impact resistance of steel pipe, but also overcomes the disadvantages of easy corrosion, pollution, and scaling of steel pipe in water, low strength, and poor fire protection performance of plasti

The pressure ratio of spiral steel pipe on gas pipelines also tends to decrease gradually. The pipe diameter, pressure, and pressure ratio need to be optimized and compared. When the output is determined, the pipe diameter, pressure, and pressure ratio are determined by optimization. If higher press

Welding of galvanized steel pipes should pay attention to:1. Galvanized steel pipes with a diameter greater than 100mm should be connected with flanges or special ferrule-type pipe fittings.2. To ensure the quality of welding, the galvanizing of the weld should be treated at the welding joint of the

1. What is GB A312 stainless steel pipe?GB A312 stainless steel pipe refers to stainless steel pipes that meet the national standard GB/T 14976-2012 "Stainless Steel Seamless Pipe". Stainless steel pipe is a kind of pipe with corrosion resistance, which is widely used in chemical, petroleum, medicin

First, causes of curling of stainless steel pipes1. Production equipment problems: In the production of stainless steel pipes, if the equipment is unstable or improperly adjusted, curling is likely to occur. For example, unbalanced roller installation, roller damage, loose drive chain, etc. may caus

First, the importance of application temperatureWhen selecting steel pipe materials, it is crucial to understand their application temperature range. Different materials have different heat resistance, and using them beyond their design temperature range will cause deformation, breakage, or other sa
