PVC drain fitting is made of sanitary polyvinyl chloride (PVC) resin as the main raw material, with appropriate amount of stabilizer, lubricant, filler, color enhancer, etc., extruded by plastic extruder and injection molded by injection molding machine, and completed the production of pipes and fittings after cooling, curing, shaping, inspection, packaging and other processes.
What are the commonly used PVC drain fittings?
1. Straight-through fittings: Straight-through fittings are fittings that connect two straight pipes, generally using socket connection. According to the use requirements, straight-through fittings can be divided into single straight-through and double straight-through.
2. Elbow fittings: Elbow fittings are used to connect two pipes that are not in the same plane, and elbows of different angles such as 90 degrees and 45 degrees are available.
3. Tee fittings: Tee fittings are mainly used to connect three pipes, and appropriate tee fittings can be selected according to actual needs.
4. PVC WYE: PVC WYE is a special tee fitting, mainly used to connect two pipes that are not in the same vertical line.
5. PVC End Cap: The end Cap is mainly used to block the end of the pipe to prevent debris from entering the pipe.
6. Reducing pipe fittings: Reducing pipe fittings refers to pipe fittings with different diameters at both ends, which are usually used to connect pipes of different diameters to meet the needs of drainage systems.
Connection method
1. Sealing rubber ring connection: This method is suitable for PVC water pipes with a diameter greater than or equal to 100 mm. The connection is made by using a flexible sealing ring to ensure the stability and sealing of the connection.
2. Adhesive connection: Suitable for PVC water pipes with a diameter of less than 100 mm. This method is achieved by using special glue and PVC joints. It requires the spigot part of the pipe to be coated with glue and inserted into the joint. Ensure that the glue is evenly applied and wait for curing to achieve a firm connection.
3. Flange connection: Mainly used for the connection between metal pipes and plastic pipes, or for crossing sewers or other pipes. Flange connection uses special flanges and bolts to tightly connect two pipes or pipes with valves, and is suitable for the connection between the valve and the pipe before and after.
Product advantages
PVC drain fitting is widely used in various drainage systems due to its excellent physical and chemical properties. This material has the following characteristics:
1. Corrosion resistance: PVC material has good resistance to a variety of chemical substances and is not easily corroded, thus ensuring the long-term and stable operation of the drainage system.
2. Durability: PVC pipe fittings are durable, can withstand certain pressure and weight, and are suitable for various environmental conditions.
3. Low cost: Compared with metal pipes, PVC pipe fittings are lower in cost and easier to install, reducing overall costs.
4. Environmental protection: PVC materials are recyclable, have little impact on the environment, and meet the requirements of sustainable development.
5. During the production process of PVC drain fittings, different additives can be added to enhance its heat resistance, toughness, ductility, etc. to meet different usage requirements.
