The performance advantages of common B-type pipes are as follows:
1. HDPE winding structure wall B-type pipe
(1) Excellent physical performance
High ring stiffness: The inertia distance is continuously adjustable and has a large value. The ring stiffness of the pipe is high, and pipes with a diameter of DN1500 or more can still produce pipes with a diameter of 16kN/㎡ or more, which can better withstand external pressure.
Good flexibility: Good extensibility, able to adapt to construction and foundation settlement under poor foundation conditions, and can be bent appropriately according to needs.
Lightweight: Compared with similar pipes, HDPE B-type pipes are lighter, easier to install and transport.
(2) Stable chemical properties
Corrosion resistance: Made of high-density polyethylene, it has good corrosion resistance and can effectively resist the erosion of most acid, alkali, and salt solutions.
Anti aging: good anti-aging performance, can be used outdoors for a long time.
(3) Reliable connection performance
Good sealing: Adopting a plug-in electric fusion connection, the pipe and fittings are fused into one through electric fuse heating, which can effectively prevent leakage.
Secure connection: The interface adopts both socket and electric melting methods to ensure the load-bearing capacity of the pipe interface.
Good hydraulic performance: The inner wall surface is smooth, and the roughness coefficient of the pipeline is n=0.009. Under the same pipe diameter conditions, the flow rate is higher than that of reinforced concrete pipelines.
2. B-type light pipe
(1) Good heat dissipation performance
Large heat dissipation area: Multiple heat dissipation channels are formed through cross arrangement or S-shaped connection, resulting in a larger heat dissipation area.
Uniform heat dissipation: It can evenly dissipate heat in all directions, making the indoor temperature more balanced.
(2) Strong pressure bearing capacity: Using excellent seamless steel pipes and good welding processes, it can withstand high working pressure and ensure the stable operation of the heating system.
(3) Good durability: Made of steel pipe, it is not easy to rust or damage, and the inner cavity is treated with excellent internal anti-corrosion materials for a long service life.
3. B-type cast iron pipe
High strength and hardness: Made of cast iron material, it has high strength and hardness, and can withstand large pressures and loads. It is not easy to deform or break when buried or subjected to external pressure.
Good sealing: Using flexible connection methods, such as rubber ring sealing interfaces, this connection method can provide good sealing and effectively prevent pipeline leakage.
Strong adaptability: It has a certain degree of flexibility and can adapt to terrain changes and foundation settlement to a certain extent.
4. B-type flexible waterproof conduit
Strong pressure bearing capacity: The wall thickness is uniform, and after cold rolling and other treatments, it can effectively eliminate the problem of excessively large outer diameter ellipses and withstand high pressure.
Strong corrosion resistance: Made from austenitic stainless steel as raw material, it has strong corrosion resistance.
Stable quality: Through certain processing techniques, the stability of quality is ensured.
