Large-diameter pp pipe is an important pipeline for sewage and an important part of urban water supply, so it has higher requirements for drainage pipes. The large-diameter pp pipe can meet the requirements of pipeline layout and drainage, and has outstanding performance. The advantages of large-diameter pp pipe water supply pipes are introduced below. The…
The purpose of ultrasonic testing of pipes is to find various defects in the manufacturing process of pipes. PP pipes avoid putting pipes with dangerous defects into use, and the possible defects (such as fatigue cracks) of pipes in service can also be detected by sample testing. Carry out quality control. According to the actual…
PP pipe has strong corrosion resistance, good corrosion resistance to non-oxidizing acids (hydrochloric acid, dilute sulfuric acid, hydrofluoric acid, dilute nitric acid, alkali and salt solution), concentrated nitric acid, fuming sulfuric acid, chlorinated Acid and other strong oxidizing acids are excluded; PP pipe has high strength, excellent impact resistance and tensile strength; PP pipe has…
The pp pipe has the characteristics of corrosion resistance, high strength, water leakage resistance, small internal resistance, compressive strength, bending strength, low engineering cost, long service life, convenient installation and maintenance, etc. The maximum application temperature of PP pipe is around 95 degrees, and the heat transfer coefficient of this product is only 1/200 of…
PP air ducts are widely used for their excellent corrosion resistance, so how should customers choose the wall thickness when purchasing PP air ducts? First of all, the wall thickness of the square PP duct depends on the application of the PP duct. In depth, the main factor affecting the wall thickness of the PP…

“Plastic performance is the foundation of injection molding technology”, mastering the process performance and characteristics of various plastics is the basic professional knowledge that every injection molding worker must understand. The performance of plastics is the basis for setting “injection molding process conditions”. One of the factors that must be considered when analyzing quality problems…
PP air duct is produced by stamping method and high-speed extrusion method. The punching method is to punch holes with a punch, roll with a roll at the same time, flatten with a mandrel continuous rolling mill, and indirectly extrude in an extruder with a high-speed extrusion method. The pipe processed by this method has…
The choice of PP air duct must be based on its material properties and cannot be sloppy. PP air ducts are widely used in chemical industry, environmental protection, food hygiene, building water supply and drainage and other fields. It can transport various corrosive media below 90℃. Its stiffness and load-bearing strength are superior to traditional…
PP air ducts are mainly used in industrial and construction projects, and the application areas mainly include: the electronics industry of clean room purification systems, pharmaceutical and food aseptic workshop purification systems, hotels, factories, office buildings, shopping malls, air conditioning systems, industrial pollution control and dust , smoke and exhaust ducts, industrial environments, such as…
