HDPE is a part of the plastic recycling market with rapid growth. This is mainly because it is easy to reprocess, has a limited degradation characteristics and is widely used in packaging. The main recycling is to reprocess 25% of recycled materials, such as post consumer recyclables (PCR), with pure HDPE to make bottles not in contact with food. In addition, due to the good insulation performance of HDPE storage tanks, polyethylene is used in many cables, and has good impact resistance even in low environment, In addition, this type of storage tank is more convenient for processing, and can be processed again after use, but it can not be used in industries directly contacting food after secondary processing.

During the processing of PPH winding tank, there are three core points: tank body fabrication, internal and external weld welding, and manhole installation. These three core points will affect the integrity, aging resistance, leakage resistance, service life, mechanical strength and other properties of the tank. PPH granular material is melted on the spiral extrusion winding unit, and then the melted extrusion material forms a tank on the mold, and demoulding is carried out after the temperature is reduced to a certain degree, so as to ensure the integrity of the tank. However, the traditional processing method is plate butt welding to form a tank body. Since the z width of the plate is 2000 mm and the tank body height is generally more than 2000 mm, in actual processing, the tank body is formed by manual welding of sections of the tank body. Then, to be safe, a stiffening ring is added at the joint of the tank body. PPH winding tank is formed by direct processing of PPH particles, without secondary processing. Traditionally, particles are processed into plates, and then the plates are processed into tank bodies; In addition, the PPH winding tank has no problems of joints, welds and leakage, and the overall mechanical strength is far greater than that of tanks processed by traditional processes because of the need for chamfer welding.

PPH storage tank is more advanced in materials and processing technology than polypropylene storage tank, but this will not lead to the price of the former being significantly higher than the latter, which is mainly due to the removal of intermediate profits and labor saving in the intermediate plate link. The whole tank body is thin and thick, so that the whole cylinder body is evenly stressed, the design is reasonable, and the mechanical strength and safety reliability of the tank body are guaranteed. In addition to being able to safely fill various corrosive liquids and having good sealing performance, the tank is light in weight and clean in appearance, and has more reliable advantages than plastic roll forming technology, plastic plate welding, FRP roll, hand glue technology, carbon steel lining technology and other technologies. The welding of the bottom of the tank and the bottom of the tank is the part that bears the large stress z. The internal and bottom of the tank are welded by mechanical cantilever, which can realize the large welding once without repeated welding, ensure that the tank and the tank will not leak under the rh condition, and can safely withstand various corrosive liquid operations.

In the use of PPH storage tank, the process of reaction material mainly depends on the change of storage tank temperature to realize the reaction. When designing PPH storage tank, its pressure and temperature should be standardized. The pressure here refers to the gauge pressure unless otherwise specified. Working pressure refers to the possible high pressure at the top of the container during normal operation. Design pressure: the pressure used to determine the shell thickness at the corresponding design temperature. 1.05 times the high working pressure shall be taken for the internal pressure vessel, and the static pressure of the liquid shall be included. The design pressure of external pressure vessel shall not be less than the possible large internal and external pressure difference under normal operation; Test pressure: refers to the pressure at the top of the vessel under pressure test; The vacuum vessel is designed according to the external pressure. When a safety control device (such as a vacuum relief valve) is installed, the design pressure is taken as the smaller value of 1.25 times the internal and external pressure difference or 0.1MPa, or 0.1MPa if there is no safety control device.

Safety method for HDPE storage tank operation: When entering the construction site, workers shall wear safety helmets and fasten safety belts for high-altitude operation. Foam fire extinguishers and other fire-fighting equipment shall be placed separately on site. In case of any abnormal phenomenon during the pressure test of HDPE storage tank, it is strictly prohibited to operate under pressure. If there is abnormal movement of rh during commissioning, it shall be parked for inspection. When installing HDPE storage tanks, special personnel shall be assigned to command the lifting and commissioning, and multiple command is prohibited. When lifting HDPE storage tanks, irrelevant personnel are not allowed to enter the site. When lifting heavy objects, the rh person shall not stand below, and the construction site shall be provided with a protective fence. Construction power needs to be connected by special electricians, and non special electricians are not allowed to connect. The construction site is an extension of the factory area. It is forbidden to hit other equipment and process pipes during construction. The original pipes or equipment shall be drilled and approved before construction. HDPE tanks are widely used because of their superior performance. While focusing on personal safety, everyone can increase efficiency and product value through safety measures. The above is about the safety method of HDPE storage tank operation. You can understand that good results can be achieved only by following the correct operation method in the use process.

Pph storage tank is a kind of plastic container made by rotational molding process. it has become the equipment needed for chemical industry, smelting, mining and new materials. Do you know what problems should be paid attention to during the installation and use of pph storage tank? The platform for installing pph storage tank shall be able to bear the weight of storage tank and solution. The platform shall be flat and smooth to prevent some sharp objects from damaging the storage tank. If heavy additional equipment is installed on the tank, or if a person needs to work on the top of the tank but the tank cannot bear the weight of a person, support or related equipment should be used to assist in the operation. When the liquid inlet is higher than the tank bottom, the liquid inlet shall bend towards the tank wall to let the incoming liquid flow along the tank wall, so as to reduce the direct impact of liquid on the tank bottom. When storing chemical liquids, first communicate with the manufacturer to determine the specifications of storage tanks, such as thickened storage tanks. In use, if pph storage tank needs to be monitored, it can be monitored by level gauge or induction device. When it has been used for a long time, please refer to the storage requirements of pph storage tank and clean the residual liquid in the tank in time. If a large amount of liquid is sucked in and discharged from the pph storage tank, special technicians need to be arranged to install the corresponding exhaust pipe.
