PVC gas pipe
Material: Polyvinyl Chloride (PVC-U)
Bore (mm): 20mm - 630mm
Pressure (Mpa): 0.6 Mpa - 2.5 Mpa
Color: Black
Features: Lightweight PVC-U material: The density of PVC-U is only 1/10 of cast iron, making transportation and installation easy, thus reducing costs. Excellent chemical resistance: PVC-U has excellent resistance to acids and bases, except for strong acids and bases or strong oxidizing agents near the saturation point. Non-conductive: UPVC material is non-conductive and not affected by electrolysis or corrosion by electricity, so no secondary processing is required. Non-flammable and non-combustible: There are no fire safety concerns, and it is cost-effective. The use of PVC-U adhesive for bonding has been proven reliable and safe, with simple operation, durability, excellent weather resistance, and resistance to bacterial and fungal decay. Low resistance and high flow rate: The smooth inner wall reduces fluid friction losses and makes it easy to maintain with less dirt adhering to the smooth pipe walls, resulting in lower maintenance costs.
Features: Advantages of uPVc Pipe for Coal Mines (versus Traditional Materials)
(1) Lightweight and easy to handle
(2) Corrosion-resistant
(3) Strong chemical stability
(4) Low fluid resistance
(5) Aging-resistant, long-lasting
(6) Low Price
(7) Easy to connect, with convenient construction and low installation costs
2. The advantages of Qiwu Brand UPVC coal mine pipes over other plastic coal mine pipes are as follows:
(1) It's not just physical blending; there's also material modification and innovative production structure.
(2) Under the same usage conditions, the thin-walled tubes with a larger inner diameter offer higher fluid throughput and are more cost-effective than other types of piping materials.
(3) Not only static-dissipative, but also flame-retardant. A dual-resistant plastic tube.
Application: PVC gas pipes are suitable for water supply and drainage, gas extraction, and ventilation in coal mine shafts. For gas extraction pipelines, materials with at least a 0.6MPa pressure rating must be selected, otherwise the pipes may collapse under vacuum (negative pressure). According to relevant safety regulations, UPVC pipes for coal mines are strictly prohibited from being used for conveying any gas at pressures above 0.1MPa. Liquid pressure testing should be used for UPVC coal mine pipes during testing, and gas testing is not allowed.
Cautionary Notes:
(1) PVC gas pipes offer many advantages, but their drawback is that they are less strong than steel pipes. Therefore, during installation and disassembly, it is crucial to prevent severe impacts to avoid damaging the pipes, fittings, or causing hidden cracks.
(2) The color of the PVC gas pipe is black. When exposed to the sun, the sunny side absorbs solar heat and the temperature rises rapidly, while the back side temperature rises slower, causing temperature difference stress and bending of the pipe. Therefore, it should be stored indoors and sunshade measures should be taken outdoors.
