PVC Connectric Reducer

The "PVC elbow" is a kind of pipe fitting used to change the direction of PVC pipes.  There are maily for ,DN32*25,DN 40*25,DN50*25,DN75*25,DN40*32,DN50*32,DN75*32,DN50*40,DN70*40,DN75*50 with 90 degree ,45 degree , Straight Joint,  Concentric Reducer and Tee Joint,etc .The following is an introduction to it from aspects such as materials, specifications, features, and application scenarios:

Materials
Main Components: It is mainly made of polyvinyl chloride (PVC) resin as the main raw material, with an appropriate amount of additives such as stabilizers, lubricants, and fillers added. It is manufactured through processes such as mixing, granulation, and extrusion molding. The PVC material has good corrosion resistance, water resistance, insulation property, and mechanical strength, and can adapt to different usage environments.
Functions of Additives: The stabilizer can improve the stability of PVC during the processing and usage processes, preventing it from decomposing due to factors such as heat and light. The lubricant helps to improve the fluidity of PVC during the extrusion process, making the molding process smoother. The filler can reduce costs and, to a certain extent, enhance the hardness and rigidity of the PVC elbow.

Specifications
Diverse Sizes: Common specifications of PVC elbows range from DN15 (nominal outer diameter of 15mm) to DN300 (nominal outer diameter of 300mm) or even larger, which can meet the connection requirements of pipes with different diameters.
Angle Classification: The angles are usually two common types, 45° and 90°. There are also some elbows with special angles, such as 30° and 60°, etc., to meet different pipeline laying requirements and spatial layouts.

Features
Convenient Installation: The PVC elbow is light in weight, making it easy to handle and install. Moreover, it can be connected to PVC pipes through simple socket or adhesive bonding methods, without the need for complex welding or other special tools, which greatly improves the construction efficiency.
Good Corrosion Resistance: It has good tolerance to chemical substances such as acids, alkalis, and salts, and is not easily corroded. It is suitable for pipeline systems transporting various corrosive liquids or gases, such as in the fields of chemical industry, electroplating, sewage treatment, etc.
Low Water Flow Resistance: The inner wall is smooth, and the resistance is small when water flows through it. It can effectively reduce energy consumption, ensure the smooth operation of the pipeline system, and reduce operating costs.
Economical Price: Compared with elbows made of other materials, such as metal elbows, the price of PVC elbows is relatively low, and it has a high cost-performance ratio, which has great advantages in some projects that are sensitive to costs.

Application Scenarios
Building Water Supply and Drainage Systems: In the indoor and outdoor water supply and drainage pipelines of buildings, it is used to change the direction of water flow and achieve a reasonable layout of the pipelines, such as the drainage pipelines in bathrooms, kitchens, balconies, and other parts, as well as the rainwater drainage systems of buildings.
Chemical Pipeline Systems: In chemical production, it is used to transport various corrosive chemical raw materials, intermediates, and products, etc. It can withstand the erosion of chemical media and ensure the safe and stable operation of the pipeline system.
Electrical Wire Threading Protection: In electrical installation projects, it can be used as an elbow for the protective sleeves of wires and cables, playing a role in protecting wires and cables from external mechanical damage and corrosion. At the same time, it is convenient for the laying and threading operations of wires and cables.
Ventilation Systems: In some ventilation and air exchange systems, it is used to connect ventilation pipes, change the direction of the air flow, and achieve a reasonable circulation and distribution of air, such as basement ventilation and workshop ventilation.
