Description PERT pipe equipment PERT pipe production line to warm the pipe device to warm the pipe production line PE-RT floor heating pipe production line: 1, good stability and long-term pressure resistance: Pipe homogeneous good, stable performance PERT pipe equipment, has good resistance thermal creep resistance, excellent long-term resistance to hydrostatic capabilities; 2, easy to bend the pipe PERT pipe equipment prices, convenient construction :: small bending radius (R minimum = 5D), the curved portion of the stress relaxation can quickly be avoided during use due to stress concentration caused by destruction of the pipeline occurs at the bend. PE-RT pipe can melt connection, and thus the pipe in the application process easy to repair if damaged. 3, good impact resistance Qingdao PERT pipe equipment, safe, low-temperature embrittlement temperature up to 70 degrees, at low temperatures the Environment, Transport, Construction; 4, anti-aging, long life: Due to the excellent material properties of PE-RT, at an operating temperature of 70 ℃, pressure 0.8MPa conditions, PE-RT pipe can be used safely for more than 50 years. 5, the process easy PERT pipe equipment, quality control is easy; 6, waste pipe can be melted, recyclable. One, PERT pipe production processes raw + masterbatch mix → → → raw material vacuum drying → single screw extruder → spiral mold → → spray vacuum sizing sleeve styling spray cooling water tank box → → → Stenciling crawler tractor → winder → finished product testing package two, PERT pipe production process incurable 1. How to solve the pipe surface coke may be due to trace the body or head temperature is too high; the head and did not clean the filter ; pellets impurities; poor thermal stability raw or heat-stable dose is too small; temperature control instrumentation failure. 2. The pipe surface with black stripes possible causes head temperature is too high, the filter is not clean. 3. Pipe Matte probably die temperature is too low or too high. The pipe surface wrinkles may be uneven temperature die four weeks; cooling water is too hot; traction too slow. 5. rough inner wall of the pipe may be lower mandrel temperature; body temperature is too low; screw temperature is too high. 6. pipe inner wall cracks may be expected to have impurities; mandrel temperature is too low; low body temperature; traction too fast. 7. Screw the tube wall may have uneven temperature is too high; screw speed is too fast. 8. tube wall material bubbles may damp. 9. uneven wall thickness may die, mandrel no positive; head temperature uneven; traction unstable; compressed air is unstable. 10. Pipe bending pipe wall thickness may uneven; head around the uneven temperature; head cooling tank, traction cutting centers no positive; different ends of the cooling tank hole heart. 11. brittle hair products may not be the extent of plasticized body; screw speed is too fast; head temperature is too low; resin viscosity is too high. 12. vertical or horizontal pipe sizing sleeve may shrink large radial die bore a large difference (horizontal); High Speed ??Traction (vertical). 13. The sudden discharge screw feed zone may slow high temperature; body water; melt pressure head small PERT pipe equipment manufacturers | days Nobuyasu (certified) | PERT pipe equipment provided by the Qingdao-day letter Thai Plastic Machinery Co.
