Aluminum alloy pipeline market demand is very broad

In order to realize the automatic welding of aluminum alloy pipe loop seam, according to the characteristics of energy saving and environmental protection super pipe loop seam, a test fixture for automatic welding of aluminum alloy pipe loop seam was developed. A series of tests were carried out to determine a set of automatic welding process specifications for aluminum alloy pipe loop seam.

The steel lined plastic pipe forms a small circular arc groove by using the cold extrusion principle at a certain distance from the end face of the pipe, and then puts the clamp-type stainless steel clamp-ring into the groove, and covers the nut or the interface, the new enamel pipe fittings and their accessories, which can be tightened and installed quickly.

Due to the conical self-locking design of the fit part of the clasp and the use of the end and radial two-way seal design, it has reliable connection strength and anti-leakage performance. At the same time, all the pipe joints are of detachable structure, and the special live pipe parts make it very convenient to maintain.

It is reported that the structure of the new dalian aluminum alloy pipeline is characterized by the third generation of continuous winding glass reinforced plastic sand pipe, which is formed through "3D printing" and compact, not only light weight, high strength, and energy saving, environmental protection, corrosion resistance immortal, convenient construction. At present, it has been widely used in domestic petroleum, chemical industry, water conservancy, papermaking, electric power, urban water supply and drainage, sewage treatment, large-scale heat supply, pipe insulation and so on, and the market demand is very broad.

Oblique core-pulling is one of the difficult points in die casting design for castings with oblique hole or concave and convex. The shape of pipeline casting is complex and belongs to irregular thin-walled porous casting. In addition to the core pulling in the direction of mold opening and both sides of the core pulling in the direction of moving and fixed mold, the casting inner wall also has an oblique hole, which requires the core pulling in an oblique direction.
