PPH wound storage tank is a common large plastic storage tank, and also a promising plastic storage tank today. PPH winding tank Its advantages mainly lie in the upgrading of its processing technology, which makes it stand out in many categories of plastic storage tanks.

There are three key points in the manufacturing process of PPH winding storage tank:

(1) Can production

(2) Internal and external welding

(3) Manhole installation.

These three core points will affect the integrity, aging resistance, leakage resistance, service life, mechanical strength and other properties of PPH winding tank.

PPH winding tank is produced by spiral extrusion winding process. The PPH granular material is melted in the spiral extrusion winding machine. The extruded material melts and forms a pot on the mold. The traditional processing method is to weld the steel plate to the tank body. Because the width of the steel plate is 2000mm, and the height of the tank body is usually more than 2000mm, the tank body is manually welded and formed when it is actually processed. For protection, a stiffening ring is added at the joint of the tank body.

Compared with the two processes, PPH winding tank is directly processed from PPH particles, without secondary processing. Traditionally, particles are processed into plates and then into containers. In addition, the wound storage tank of PPH has no joint welding and no leakage. In addition, due to non chamfer welding, the overall strength is much higher than the traditional manual processing groove. PPH storage tank

PPH back plate and automatic welding is a kind of welding unit for winding groove. The welding of roof and floor is a long arm extrusion welder. After chamfering, the traditional processing process is mainly manual welding. Manual arc welding is used for food production. The degree of manual welding cannot be controlled, and materials and electrodes are difficult to be dissolved in one whole. All tanks in the process of integrity and PPH winding avoid this kind of problem. In addition, the manual welding seam is slightly higher than the tank body, while the PPH wound storage tank is formed by a certain arc pull welding, and the weld seam is 50mm higher than the tank body.

The manhole of plastic storage tank plays an important role in processing. The manhole is generally opened at the bottom and top of the side of the tank for easy maintenance and observation. The manhole weld of PPH winding storage tank is welded by a large automatic extruder. Similarly, the traditional process is formed by manual welding.

To sum up, the performance of PPH wound storage tank is far higher than that of storage tank made by traditional process, and it has the advantages of good integrity, corrosion resistance, leakage resistance, aging resistance, stable quality, high welding strength, high aesthetics, no welding flange, etc.
