Product Details
Mine-used polyvinyl chloride (PVC) pipe is made of polyvinyl chloride as the main raw material, mixed with high-quality conductive carbon ink and flame retardant, and processed by one-step extrusion. It adopts new technology formula and light-weight and high-strength flame-retardant antistatic materials, and its product quality meets the requirements of the PVC pipe standard for coal mine gas drainage. It meets and exceeds the national coal industry standard MT181-88 "Safety Performance Specification for Plastic Pipes in Coal Mines" and MT558.2-2005 "Safety Performance Test Specification for Plastic Pipes Used in Coal Mines" and other standard requirements.
Advantages of mining PVC pipe products
Compared with common steel pipe materials, it has the following advantages:
1: The quality is small.
The specific gravity of PVC pipe is only 1/5 of that of steel pipe, and its weight is much smaller than that of steel gas drainage pipe
2: Good safety performance.
PVC pipe does not produce sparks, and other metal materials may produce sparks when they are impacted, impacted, rotating friction and other actions.
3: Corrosion resistance and longer service life.
Gas contains corrosive gases such as hydrogen sulfide, sulfur dioxide, carbon dioxide, and long-term humidity, which has obvious, violent and rapid corrosion effects on metal materials. The molecular chain of PVC pipe material is stable, not easy to be corroded by acid and alkali, and has a long life.
