Types of PVC pipe in singapore:
45° elbows in singapore are pipe fittings and pipe connectors. Used in main pipelines and branch pipes. Used to change the pipe direction.
Generally, the 45° elbow used in daily life is made of PVC material, because of its better quality, it is more convenient to use.
The ways of connecting the pvc45° elbow to the pipe include direct welding (the most common way) flange connection, hot melt connection, electrofusion connection, threaded connection, socket connection, etc. According to the production process, it can be divided into welding elbow, stamping elbow, push elbow, casting elbow, etc.
The 90° elbow in singapore made of PVC is a kind of connecting pipe commonly used in plumbing installation. It is used for the connection at the end of the pipe to change the direction of the pipe.
Other names: 90° elbow, right-angle elbow, love and bend, stamping elbow, pressing elbow, mechanism elbow, welding elbow, etc.
Uses: Connect two pipes with the same or different nominal diameters, so that the pipes can be turned at 90° and various degrees.
Downstream tee is a kind of pipe fitting in drainage pipeline, which is used for vertical connection of branch pipe and main pipe. Although it is a vertical connection, the connection where the branch pipe enters the main pipe does not intersect vertically but is connected with a small arc along the flow direction of the water, so that the water in the branch pipe flows smoothly to the main pipe. The small arc of the PVC downstream tee that is usually used plays a role in the downstream.
The cross in Singapore is a pipe fitting and a pipe connecting piece. Also called pipe fitting cross or cross pipe fitting, a cross joint, is used at the branch pipe of the main pipeline.
The PVC spools are divided into equal diameters and different diameters. The ends of the pipes of the equal-diameter spools are all the same size; the size of the main pipe of the reduced spool is the same, and the size of the pipe of the branch pipe is smaller than that of the main pipe. A spool is a pipe fitting used at the branch of a pipeline.
Usually,pipe hoop in Singapore the plumber is also called direct in the process of use.
Purpose: A pipe clamp is a short piece of pipe used to connect two pipes. The PVC pipe hoop is also called the outer joint. The pipe hoop is widely used in civil construction, industry, agriculture, and other fields because of its convenient use.
Specifications of PVC pipe fittings
PVC specifications in Singapore are 16mm, 20mm, 40mm, 50mm, and 110mm refer to the diameter of the pipe. 16mm and 20mm are used for threading pipes. 40mm and 50mm for downpipes. 110mm is used for launching the main pipeline and toilet launching.
The price of PVC pipe fittings in singapore of different specifications is also different. Generally, the price of 50 specifications is about $0.5 . Of course, the higher the specification, the higher the price. Because it is a commonly used material, it must be acceptable to the public and not too expensive.
Raw material selection of PVC pipe fittings
PVC resin: The degree of polymerization of the resin determines the size of the molecular weight. Too large and too small molecules are not good for injection molding. The average degree of polymerization of SG-7 type resin is 750~850; the average degree of polymerization of SG-8 type resin is 650~750. Both resins are more suitable for injection molding.
Stabilizer of pvc pipe fittings
If no stabilizer is added to pure PVC resin, it will degrade and release HCl gas when the temperature in the air is higher than 150℃. Stabilizers commonly used in pipe fittings include lead salts, calcium zinc stabilizers, organotin, and rare earth stabilizers. Organotin is environmentally friendly but expensive and is rarely used in pipe fittings.
Lubricants of pvc pipe fittings
There are two types of internal and external lubricants, but there is no specific boundary between internal and external lubrication. Most lubricants have both internal and external lubrication properties, but according to the principle of polarity compatibility, the internal and external properties are biased. . Excessive internal lubrication will make the product brittle and the impact resistance will decrease; excessive external lubrication will cause the product to peel and delaminate, and poor plasticization will affect the surface and mechanical properties.
Fillers of pvc pipe fittings
The addition of fillers can reduce costs, reduce shrinkage, and increase the rigidity and dimensional stability of products. Generally, the fillers used are light calcium carbonate. Some customers will add some high-mesh heavy calcium, which requires high There is also the use of nano-calcium carbonate.
Modifiers of pvc pipe fittings
Processing modifiers can improve processing performance, accelerate plasticization, and improve the surface finish of products. The modifier generally referred to is the ACR processing modifier. There are many kinds of ACR, and the quality of manufacturers varies. PVC-U pipe fittings have relatively high requirements for fluidity, and good fluidity can obtain relatively high surface quality and mechanical properties. , especially can significantly reduce the occurrence and quantity of butterfly spots, etc. At this time, ACR should choose products with fast plasticization, relatively small melt strength, and viscosity.
When we produce PVC pipe fittings, we must use good PVC resin materials, good stabilizers, good lubricants, and good modifiers. These quality guarantees are all to win the favor of the singapore market. The reason why we have a place in the Singapore market has a lot to do with our strict quality control, genuine materials, and high-tech production technology.
