Stub in flange is a pipe connector, mainly used to connect pipes, valves or equipment, and is sealed and fixed through flange connection. In specific applications, can withstand high pressure and temperature, has good sealing performance and corrosion resistance, and ensures the safe operation of the pipeline system.
Function
The main function of the short pipe flange is to achieve seamless docking between pipes, ensure the smooth flow of fluids, and effectively prevent leakage risks. Its structural design is reasonable, and the stable connection between pipes is achieved through the close fit of the flange and the firm locking of the bolts. In addition, the short pipe flange has a variety of specifications and models, which can be customized according to different application scenarios and fluid characteristics to meet the needs of various complex working conditions.
Differences between PVC and PE Stub in flange
The main differences between PVC and PE Stub in flange are in terms of material properties, application scenarios, connection methods and prices.
1. From the perspective of material properties, PVC has good tensile and compressive strength, but poor flexibility, excellent corrosion resistance, but is brittle at low temperatures and easy to decompose. In contrast, PE is light in weight, good in toughness, good in low-temperature resistance, non-toxic, and has high impact strength, but low in compressive and tensile strength.
2. In terms of application scenarios, PVC material is often used in drainage pipes, rainwater pipes and other occasions due to its low price and high hardness. PE material is often used in underground gas pipelines, tap water pipelines and other occasions with high requirements due to its excellent low-temperature resistance and toughness.
3. In terms of connection methods, PVC Stub in flange usually adopts bonding, socket rubber ring connection, and flange thread connection. PE Stub in flange requires hot melt technology for connection, and hot melt welding, flange thread connection and other methods can also be used according to the size of the pipe diameter.
4. In terms of price, the price of PVC stub flange is relatively low, while the price of PE stub flange is relatively high due to the particularity of materials and connection methods.
Advantages and features
1. Sealing: Stub in flange ensures a close fit with the matching gasket through a flat and smooth flange surface and a precisely formed sealing groove to prevent medium leakage.
2. Stability: Its design helps to improve the stability of the entire piping system, reduce vibration and displacement, and ensure long-term stable operation.
3. Applicability: Stub flange is widely used in many fields such as petroleum, chemical industry, electricity, and construction to meet the connection requirements under different working conditions.
4. Stub in flange also has a lightweight material and good processing performance, which is easy to install and maintain, reducing the complexity of the construction process and maintenance costs.
