I believe that everyone who has purchased PVC pipe fittings may have heard the word "Schedule", but you should not know what it means. Schedule has nothing to do with time. It is actually related to the thickness of the wall. But everyone is also very curious about the difference between Schedule 40 PVC pipe fittings and Schedule 80 PVC pipe fittings, which is more expensive than the No. 80 pipe than the No. 40 pipe. Their outer diameters are the same, but the walls of the 80th pipe will be a little thicker. Let's talk about the difference between them and how to choose the right pipeline.

The main component of PVC pipe fittings is polyvinyl chloride, and other components are used to enhance its heat resistance, toughness and ductility. PEX is a flexible tubular piping system that is connected to compression, metal or plastic insert fittings or other mechanical methods that do not require glue or heat. The flexibility of the PEX simplifies the operation of the water supply line throughout the house. A simpler installation process reduces labor when replacing PVC pipe fittings to install a new plumbing fixture. So how do you connect PEX to it? Let's talk about it.

The main component of PVC pipe fittings is polyvinyl chloride, a material added with other ingredients to enhance its heat resistance, toughness and ductility. The uppermost layer of this surface film is lacquer, the main component in the middle is polyvinyl chloride, and the lowermost layer is a back-coated adhesive. PVC pipe fittings are made of polyvinyl chloride resin, stabilizers, lubricants, etc., and then extruded by hot pressing. They are the first plastic pipes to be developed and applied. PVC pipe fittings have strong corrosion resistance, easy adhesion, low price and hard texture. Plastic pipes are used for drainage, wastewater, chemicals, heating and coolant, food, ultrapure liquids, mud, gas, compressed air and vacuum systems.

The main component of PVC pipe fittings is polyvinyl chloride, a material that adds other ingredients to enhance its heat resistance, toughness and ductility. As one of the products of technological development, they are within reach of everyday life. PVC pipe fittings have been well received by the engineering community for their light weight, corrosion resistance, high compressive strength, safety and convenience. They are the first plastic tubes developed and applied. It can be used in drainage, wastewater, chemicals, heating and cooling, food, ultrapure liquids, mud, gas, compressed air and vacuum systems. Let's talk about its type.

PVC elbow in pipe system, elbow is the pipe that changes the direction of pipeline. According to the angle, there are 45 degrees and 90 degrees 180 degrees which are most commonly used, and other abnormal angle elbows such as 60 degrees are also included according to the needs of the project. Elbows are made of cast iron, stainless steel, alloy steel, calcinable cast iron, carbon steel, non-ferrous metals and plastics. Connection with the pipe are: direct welding (the most commonly used way) flange connection, hot melt connection, electric melt connection, threaded connection and socket connection. According to the production technology, it can be divided into: welding elbow, stamping elbow, pushing elbow, casting elbow and so on. Other names: 90 degrees elbow, right angle bend, love and bend. National Standard Process Flow of Sinopec Standard Pipe Fittings Implementation Standard.

The diameter of PVC drainpipe is standard, and 4 inches is 110 pipe. They all talk about outer diameter, because this is matched with PVC fittings. Therefore, the diameter of the tube is unable to determine the thickness of the wall because it is the same. If you want to know the thickness of the pipe wall, simply take a vernier caliper to measure directly, or the diameter of the pipe minus the size of the aperture, and then divide it by 2 to get the result. As for the 4-inch pipe, the pipe wall is 3.2 mm, is produced according to national standards, also known as national standards, such as pipe wall: 2.1MM or 2.2MM, are produced according to enterprise standards, is the enterprise standard pipe, some also called rainwater pipe, distinguish drainage pipe.

PVC exhaust elbow is composed of elbow and straight pipe. It is characterized in that the exhaust elbow can effectively discharge the exhaust gas inhaled into the hot flue, not only does it not produce negative pressure in the room, but also can induce air and improve the environment. The exhaust elbow can effectively exclude the gas, and the PVC exhaust elbow is made of PVC material.

PVC pipe drainage pipe is a kind of sanitary PVC resin as the main raw material, adding a suitable amount of stabilizer, lubricant, filler, colorant, etc. through the plastic extruder extrusion molding and injection molding machine, through cooling, solidification, finalization, inspection, packaging and other processes to complete the production of pipes and fittings.
