Steel sheet pile engineering construction is related to engineering construction waterproofing and safety, and is one of the most important technological processes of building construction.

steel pipe pile can be used under the following conditions: 1) Basic engineering of general industrial and civil buildings (structures) in areas where the seismic fortification intensity is not greater than 7 degrees.

Grinding the nozzle of seamless steel pipe: After cutting, an angle grinder should be used to polish the plastic layer of the nozzle.

For the installation and use of straight seam steel pipes, there are strict technical requirements, which must be carried out according to actual conditions and operating procedures to ensure safety and quality.

The hardness test of galvanized seamless steel pipe can be divided into two methods, one is tensile test specimen and the other is hardness test.

Following these measures can effectively control the scars of galvanized seamless steel pipes:(1) The particle size of the deoxidizer powder is generally about 16 mesh.(2) According to the inner surface area of the galvanized seamless steel pipe, the spray amount of deoxidizer is generally 1.5-2.0g/dm²...
