The high-frequency welding process of straight seam steel pipe is completed in the high-frequency welded pipe unit. The high-frequency welded pipe unit is usually composed of rolling forming, high-frequency welding, extrusion, cooling, sizing, flying saw cutting, and other components. The front end

316 stainless steel pipe with the standard export package to ensure the steel pipe obeys the transportation requirement. These stainless steel pipes are seamless steel pipes for industrial fluid transport. It's with several quality control steps to ensure the steel pipes' quality. For such fluid tra

1. It completely solves the problem of mutual friction between the closed surfaces of traditional connecting steel pipes and affects the sealing; the flow resistance is small, and the resistance coefficient of the stainless steel tee is equal to that of the steel pipe section of the same length;2. T

Austenitic stainless steel is softened by solid solution treatment. Generally, the stainless steel tube is heated to about 950-1150°C and kept for some time, so that carbides and various alloying elements are fully and evenly dissolved in austenite, and then quickly quenched and cooled. , carbon and

The resistance of the fluid is responsible for the energy loss (ie drag loss). One is the resistance loss along the way caused by the viscosity and inertia of the fluid; the other is the local resistance caused by the blockage and disturbance of the solid wall to the fluid due to the sudden expansio

Stainless welded steel pipe will be used in the construction project. These stainless welded steel pipes are flexibly applicated in energy plant construction. It featured hard resistance to applicate in various industry projects. Here are the stainless welded steel pipe exported to Malaysia. The siz

1. The main feature of ordinary seamless steel pipes is that they have no welded seams and can withstand greater pressure. Products can be very rough as cast or cold drew.2. Cold-drawn precision steel pipe is a product that has appeared in recent years, mainly because the inner hole and outer wall h

1) Thin-walled stainless steel pipes and fittings should not be in direct contact with cement, cement mortar, or concrete. When the pipeline is laid in the dark, anti-corrosion tape should be wrapped on the outer wall of the pipe or a plastic-coated thin-walled stainless steel pipe should be used.2)

The transportation of oil and gas through pipelines requires a certain pressure. The longer the pipeline, the higher the pressure required for oil and gas transportation. The pressure of long-distance pipelines is generally between a few MPa and more than ten MPa. Therefore, the pipeline must have S

1. The use of large-diameter straight seam welded steel pipes can be divided into oil well pipes (casing pipes, oil pipes and drill pipes, etc.), pipeline pipes, boiler pipes, mechanical structure pipes, hydraulic prop pipes, gas cylinder pipes, geological pipes, chemical pipes (high-pressure Fertil
