Features
l Easy to handle and convenient to construct
Produced mainly from polyvinyl chloride, it has a smooth inner wall, corrugated outer wall, and hollow between the inner and outer walls. The material is light and easy to handle and transport.
The product has a smooth inner wall with a low friction coefficient, making it easy to thread; the outer wall is corrugated with clear opening lines, facilitating easy opening for threading.
l High ring stiffness and stable performance
The high ring stiffness makes the pipe less likely to break; it can withstand the corrosion of various chemical media and has good adaptability to high-temperature environments.
The product is cold resistant, flame retardant, and fireproof, with a reliable connection and high safety factor.
l Reliable connection and less leakage
The connection uses a rubber seal ring for flexible connection, which can not only adapt to a certain amount of axial displacement but also compensate for thermal expansion and contraction caused by temperature changes, making the connection more reliable and less prone to leakage.
