Galvanize steel pipe for sale

Steel pipe is not only used for conveying fluid and powder solid, exchange heat energy, manufacturing machinery parts and containers, it is a kind of economic steel. The steel pipe is used to make the structure of the building structure, the support and the mechanical support, which can reduce the weight and save the metal from 20 to 40%, and can realize the mechanization construction of the factory. The construction of the highway bridge with the steel pipe can not only save the steel, simplify the construction, but also greatly reduce the area of the coating protection layer, save the cost of investment and maintenance.

Classification by connection
According to the pipe end connection can be divided into: light pipe (pipe end without thread) and the car wire pipe (Guan Duan with a thread).
The wire pipe is divided into: ordinary car wire pipe and pipe end upset car wire pipe.
Thick wire pipe can also be divided into: plus thick (with external thread), inside the thick (with the inside of the thread) and inside and outside the thick (with internal and external threads) and other places of the car wire pipe.
Threading pipe can also be divided into: ordinary cylindrical or conical thread and special thread, such as the wire pipe.
In addition, according to the needs of users, the car is generally equipped with pipe connector delivery.

According to the coating characteristics
According to the characteristics of surface coated steel pipe can be divided into: Clarinet (not coated) and coating tube.
The coating pipe has galvanized pipe, aluminum, chrome plated tube, alumetized tubes and other alloy layer of steel pipe.
The coating pipe is coated with an outer coating pipe, an inner coating pipe, an inner and an outer coating pipe. Commonly used coatings are plastic, epoxy, coal tar epoxy resin as well as a variety of glass type of anti-corrosion coating materials. Galvanized pipe is divided into KBG pipe, JDG pipe, screw pipe, etc.

Steel tube continuous rolling
Continuous rolling process for steel tube and sizing process. Seamless steel tube is a by steel tube and core rod together in multi frame motion process, deformation and movement of steel pipe and roll and mandrel. Mandrel can is free floating, is a full on metal driven forward movement; can also be limited motion type, also is to give a mandrel movement speed, limiting the freedom of movement. In the process of movement, the mandrel, roller and pipe connection into a whole, changes in any one of the links will cause changes in the state of the system and rolling theory is the study of the theory of the relationship between them.
