PPR pipe uses and characteristics: PP-R water pipe system is widely used in the world's developed new products PPR pipe equipment suppliers, which uses a homogeneous technology PPR pipe welding equipment manufacturers in the hot and cold water transport project, its comprehensive technology performance and economic indicators are far superior to other similar products, especially its excellent health properties, the use of waste from production to fight back the whole process can achieve high health and environmental protection requirements. Products with heat, pressure, thermal insulation long life and economic advantages. PPR pipe production process incurable 1. How to solve the pipe surface coke may be due to trace the body temperature is too high or nose; nose and filters not clean; pellets impurities; poor thermal stability or thermal material 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 PPR pipe equipment suppliers | days Nobuyasu (certified) | PPR pipe equipment from Qingdao day letter Thai Plastic Machinery Limited.
