Widely uses of thermal expansion straight seam steel pipe

thermal expansion of straight seam steel pipe has a range of models, which can be expanded from what to what model are fixed, straight seam steel pipe model and the target model itself to be close to, or pipe break. He is given by high-frequency straight seam steel pipe body hardness decreased heating so then let straight seam steel pipe from the header (header is mold, a narrow one wide, narrow tube is a normal caliber, the thickest section of the target diameter) By slowly on, when the tube completely through after reaching thermal expansion purposes.

Thermal expansion process on the straight seam steel pipe and weld material itself has a high demand, the material must meet the national standard, the carbon content must not be less, or will cause tube breakage, another seam have qualified, or in the process of thermal expansion very easy to disconnect. Thermal expansion is a certain risk. Care workers sometimes the case during thermal expansion rate is not well controlled, and other factors, it is easy to break the tube. After thermal expansion after the pipe, there will be a certain length and thickness shrunk, so in the process of purchasing the original tube, try to buy some little thicker wall thickness, and length slightly longer, so as to ensure that the thermal expansion of the walls after thickness and length to achieve the project's requirements. Generally straight seam steel pipe thermal expansion for steel.

Straight seam steel pipes are widely used, including water and structure of urban construction and other fields. During use, straight seam steel pipes some general models: can not meet the needs of the project, this time straight seam steel pipe thermal expansion to play a big role, thermal expansion is straight seam steel pipe after treatment by thermal expansion of straight seam steel pipe.
