The alloy pipe is a spiral seam seamless steel pipe made of hot-rolled steel coils as raw materials, extruded at normal temperature, and welded by fully automatic double-wire double-sided arc welding process. The alloy pipe feeds the hot-rolled strip steel into the welded pipe unit, and is extruded through multiple passes of hot-rolled strip steel. The hot-rolled strip steel is slowly rolled over to produce an annular pipe material with an opening gap. Adjust the pressing amount of the squeeze roller to make The welding gap should be controlled at 1~3mm, and both sides of the weld should be flush.
Key technical characteristics of alloy pipes:
a. In the forming process, the thick steel plate deforms evenly, has small internal stress, and does not cause scratches on the surface. The processed alloy pipes have higher coordination capabilities in the size and model ranges of diameter and wall thickness, especially in the production of steel structure design-grade thick-walled pipes, especially medium-diameter and small thick-walled pipes. The unparalleled advantages of the processing technology can meet a large number of customer requirements in terms of specifications and models of alloy pipes.
b. Adopting professional double-sided arc welding technology, the welding can be completed at the optimal position, and defects such as misalignment, welding deflection and incomplete penetration will not occur, making it easy to control the welding quality.
c. Carry out 100% quality inspection of alloy pipes so that the entire process of steel pipe processing is under reasonable inspection and supervision to ensure product quality.
d. All the equipment in the production line has the function of connecting to the computer data collection system to realize timely transmission of data, and the central control room monitors the performance parameters of the production process.
