Introduction:
High-precision seamless steel pipes are precision cold-drawn seamless pipes that are made by anaerobic tempering treatment to eliminate surface and internal stress, and then phosphating and anti-rust treatment. The product has high dimensional accuracy and good ductility. It is easy to process and bend into various required shapes without shrinking or flattening the pipe section; the pipe surface has high precision, and the surface hardness is moderate after anaerobic tempering treatment. And the surface can be installed directly without pickling and rust removal after phosphating antirust treatment.
Features:
The high-precision seamless steel pipe has a strong heat insulation function, which can ensure that the temperature of the internal transport material is not changed from the outside, and has a good cold resistance in winter. The sound insulation function of seamless steel pipe is very good, preventing the noise of liquid flowing through the pipe during transportation from disturbing people. At the same time, the seamless steel pipe can be anti-corrosion. The three-in-one seamless steel pipe produced by the high-pressure complete set of seamless steel pipe foaming equipment introduced by our company has excellent functions and strictly implements the shot blasting of the outer surface of the steel pipe and the inner surface of the outer protective pipe. The treatment process further improves the bonding function of seamless steel pipes. The material of the insulation layer is rigid polyurethane foam with a density of 60kg/m3 to 80kg/m3, which fully fills the gap between the steel pipe and the casing, and has a certain bonding strength, so that the steel pipe, the outer casing and the insulation layer Form a strong whole. The seamless steel pipe has good insulation function, and the heat loss is only 25% of the traditional pipe, which can significantly reduce the cost and save power. Excellent waterproof function, excellent resistance to acid, alkali and corrosion.
