The so-called PE double-walled corrugated pipe is a kind of pipe section with a smooth and flat inner wall and a trapezoidal or arc-shaped corrugated rib on the outer wall in order to save raw materials without reducing the ring stiffness of the pipe. The corrugations on the outer wall are hollow and made by extrusion molding process.

Read More »Reinforced Thermoplastic Pipes (RTP pipes for short) are high-pressure plastic composite pipes with good flexibility, corrosion resistance, high pressure resistance, impact resistance, wear resistance, light weight, easy connection. It can be coiled and laid quickly without joints over long distances. It can well overcome the corrosion problem of steel pipes and the pressure resistance problem of plastic pipes, and can be used in oil and natural gas extraction and long-distance transportation, and various other applications that require higher pressure transporting.

Read More »According to the rotation direction of the twin screw, the extruder can be divided into two forms: Co-rotating extruder and Counter-Rotating. Co-rotating extruder: Refers to the two screws rotating in the same direction when working, while counter rotating extruder: Refers to the two screws rotating in opposite directions when working.
