sell air hose/welding hose Description

Characteristics: 1. Tenacity: The products are made by polymerizing polyester terylene by and intwining terylene in the mesosphere of the hose, the products are produced. So the cracking of products is very high. 2. Burliness: PVC and Terylene are affixed by special engineering technology, avoiding abruption and stratification. 3. Permanence: The stuff is chosen strictly and is processed with precise filter net under consummate quality control system, leading to quality products with long life-span. 4. Pliability: The products are made by polymerizing terylene and mixing PVC at the best proportion, so the products are not only smooth but also flexible. AUTHENTICATION: Our company was approved by ISO 9001:2000, on Nov. 22nd, 2005. ISO 9001:2000 Registry Date: 2005.11.22 ISO 9001:2000 Registry Number: 4809/0 QULITY China Chemical Industry Standard Seoul’s Own Back-check Test Item Capability Test Condition Test Result Test of Inner Pressure Bursting Pressure(Mpa) No leaking water, inflating and bursting 18.9Mpa below no bursting 21.0Mpa Coefficient of Curve Distortion ≥0.8 Distortion coefficient≥0.8 when curve radii is 145.44m 0.98 Stench Intensity Outer Tier ≥10.0Mpa 15.2 Endothecium ≥7.0 Mpa 29.1 Elongation Modulus Outer Tier ≥250% 300% Endothecium ≥200% 305% Agglutinate Intensity ≥1.5KN/m Speed of peeling 25.0? mm/min 2.6 WATCHFUL PROCEEDINGS: 1. The pressure is 60kgf/c㎡ below and the temperature is 70℃ below. 2. The products should be rolled after being used. The place of safekeeping should be shady. 3. Do not knock the products by hammer when it is connected with hose, avoiding agglutinate disrepair.
