(1) We can use solvents or emulsions to clean the surface of the ASTM A252 LSAW Steel Pipe. This method is very effective for the oil and grease or dust and other organic matters on the surface of the steel pipe.
(2) In the case of rust on the surface of the steel pipe, we can use a steel wire brush to polish the surface of the steel pipe to achieve the purpose of rust removal.
(3) The spray method can also be used. This method can not only clean up all rust, oxides, and dirt, but also the steel pipe can reach the required average under the fierce impact of abrasive and the effect of friction. Roughness.
Straight seam welded steel pipe is not only used to transport fluids and powdered solids, exchange heat, and manufacture mechanical parts and containers, it is also an economical steel.
Using steel pipes to manufacture building structure grids, pillars, and mechanical supports can reduce weight, save metal by 20-40%, and can realize factory mechanized construction. The use of steel pipes to manufacture highway bridges not only saves steel, simplifies construction, but also greatly reduces the area of the protective layer and saves investment and maintenance costs.
Nowadays, our application of steel pipes is very extensive, but there will inevitably be rust in the process of using steel pipes. Rusty steel pipes will affect its normal use, so if you find rust on the steel pipes It needs to be cleaned up in time. After relevant comparative tests, it is verified that the yield pressure of the straight seam steel pipe and the steel pipe is consistent with the actual and theoretical value of the burst pressure, and the deviation is close. However, both the yield pressure and the burst pressure are lower than those of steel pipes.
The blasting test also showed that the circumferential deformation rate of the blasting port of the straight seam steel pipe was significantly greater than that of the steel pipe. This proves that the plastic deformation ability of the straight seam steel pipe is better than that of the steel pipe, and the blasting opening is generally limited to one pitch, which is caused by the strong restraint effect of the spiral weld on the expansion of the crack.
