Kind of conduit is more, according to the performance of each conduit of the environment and people use, the user can choose the right. This article is to introduce the PVC pipe threading. For dark laying in the wall, lay buried underground insulated tubes and line pipe, rural general home use threading pipe conduit class quality, required to meet a certain flame retardant to meet the physics properties of PVC conduit can be . If fire occurs in high places, such as hotels, restaurants, libraries, and some entertainment and other densely populated areas conduit reasonable prices, mostly due to the conduit is installed in a flammable floor, the ceiling, you need to threading pipe has a strong flame retardant properties. For old buildings, old houses of the second decoration, interior decoration, etc. are used in the open air, so the requirements of PVC pipe threading fire to B1 level and above. For distribution lines firefighting, automatic alarm system line of conduit will need to meet the Ministry of Public Security of the flame-retardant PVC pipe threading requirements. The reason why there is such kind of conduit is too good quality product because in general the case is a waste of resources, poor quality of products can not meet the high demand. For normal indoor environments and at high temperatures, dusty, shock and a fire hazard areas. It can also be used in a humid place. Shall in particular wet with acid, alkali, salt corrosion and potentially explosive places. Ambient temperature -15 ℃ ~ + 40 ℃. Threading pipe excellent mechanical properties. Excellent corrosion resistance threading pipe industry standards, threading pipe high strength, work pressure exceeds 2.5Mpa. Threading pipe surface is smooth, fluid resistance, no scaling, should not breed microbes. Thermal expansion coefficient, no shrinkage. Conventional mounting connection. Conduit epoxy coated layer is more effective solution to the water, buried and acid, alkali, salt corrosion of metal pipes, the age up to 50 years.
