As the 40cr smls pipe is characterized by strong impact load and alternating load, the working environment is poor, so the bearing steel with high and uniform hardness, high contact fatigue strength...
The high-frequency erw steel pipe is different from the ordinary welded pipe welding process. The weld bead is melted from the base material of the steel strip body, and the mechanical strength is...
As the epoxy powder dipping process is plagued by the problem of adhesion, the impregnation of epoxy powder has not been promoted. Currently, with the successful development of the special phosphating...
Most of the precision seamless steel tubes produced on the market are made by heat treatment. The prelude needs vacuum annealing. The lower the annealing temperature, the higher the vacuum...
The spiral tube heat exchanger according to the ssaw steel pipe structure has the advantages of strong structure, strong adaptability, wide selection of materials, easy manufacture, low production...
LSAW pipe for heating is the conduit for transporting steam or hot water and other thermal media. LSAW pipe for heating is characterized by high temperature medium, high pressure, high flow rate, will...
High-pressure boiler tubes: high-quality carbon structural steels, alloy structural steels and stainless steel-resistant seamless steel tubes for steam boiler pipes mainly used to manufacture...
The breakthrough system lsaw steel pipe, improving concentration and repeated construction is a major cause of overcapacity. For example, in the seamless steel pipe industry, as of the end of 2012...
The West-East Gas Pipeline Project is a national key project, and it is also an unprecedented large-diameter lsaw steel pipe and high-pressure long-distance natural gas pipeline project in China. In...
The external environment of straight seam erw steel pipe is tight, the steel production constraints are increasing, and the production growth rate continues to slow down. Since the fourth quarter of...
1. Fully controlled heat treatment production lineIn order to make the workpiece freely complete the required heat treatment process on the production line, the continuous furnaces of a specific...
In life, whether it is a ssaw steel pipe or a seamless steel pipe, it will rust if it is not properly maintained. Here we talk about the cleaning and rust removal of the steel pipe.cleaningSolvents...
Any two open and has a hollow cross-section, and its length and cross-section of the circumference of the larger than the steel, can be called steel. When the length and the circumference of the cross...
There are many kinds of welded pipes, such as erw steel pipes and ssaw steel pipes. The purpose of Q345B welded pipe production is to obtain a well-drawn sorbite structure. In theory, the phase change...
1. Welding of aluminum tubesThe use of high-frequency electric resistance welded steel pipe in China began in the 1950s. This process has been widely used, but the high-frequency power supply is used...
