PPH spiral wound storage tank

PPH wound storage tank is a large plastic storage tank, PPH The advantage of winding can mainly lies in the change of manufacturing process.

PPH Spiral wound storage tanks are mainly produced by storage tanks and welded with internal and external welds during processing enter Hole installation three It is composed of three core points.

PPH The particles are melted on the spiral extrusion winding device, and then the molten extrudate forms a can body on the mold. Demoulding after the temperature is reduced to a certain extent can ensure the integrity of the tank body. The traditional processing method is to weld the steel plate into a tank, because the width of the steel plate is 2000mm, tank height is generally greater than 2000mm, PPH storage tank During actual processing, a section of the tank body is manually welded to shape, and then for reliability, a strengthening ring is filled at the joint of the tank body.

PPH mixing tank The comparison of the two processes shows that, PPH The wound tank is composed of PPH Made of granular materials. The granular materials are processed into plates, and then the plates are processed into grooves.

PPH Automatic welding is a kind of extrusion welding unit for coiling tank bottom plate. The welding seams of roof and floor are mostly long arm extrusion welding units, and the traditional post chamfering manufacturing process is used, which is mainly manual welding. The grain production of welding rod, and the degree of manual welding cannot be controlled. The material and welding rod are difficult to dissolve into a whole, and the integrity is poor, PPH The winding tank process avoids such problems. In addition, the manual weld is slightly higher than the tank body, while PPH The winding can body is formed by drag welding with a certain radian, and the weld is higher than the can body 50mm。

Tank plastic tank enter During hole construction, one hole is usually opened at the bottom and top of the tank side enter Holes for maintenance and observation, PPH The large automatic extrusion spray gun is used for welding the inlet weld of the wound storage tank, and the principle is the same as that of the inner and outer weld of the bottom plate. Similarly, the traditional manufacturing process is mostly formed by manual welding.
