In the construction of modern urban infrastructure, the design and construction of sewer system is a crucial part. An efficient and durable sewer system can not only effectively discharge waste water and rainwater, but also ensure the convenience and safety of residents. In order to ensure the reliability and durability of the system, it is crucial to select the right pipes and fittings. In this field, SDR 35 sewer pipe fittings, as a commonly used pipe material, are widely used in urban drainage, sewage treatment, stormwater discharge and other aspects because of its good performance and adaptability.
SDR 35 refers to the standard metric sewer pipe pressure rating and pipe specifications, especially for use in sewage pipes and drainage systems. SDR (Standard Dimension Ratio) is the standard outside diameter ratio, which represents the ratio of the outside diameter of the pipe to the wall thickness. The pipeline design of SDR 35 is primarily for low pressure sewer applications, providing the necessary strength and toughness while maintaining good fluid transfer performance.
What are SDR 35 sewer pipe fittings?
SDR 35 sewer pipe fittings refer to a series of connection parts designed for SDR 35 pipe systems, such as elbows, tees, crosses, reducers, caps, etc. These fittings are used together with SDR 35 drain pipes to form a complete sewer system.
SDR 35 pipes are usually made of polyvinyl chloride (PVC), which has good corrosion resistance, durability and low friction coefficient, and is suitable for drainage and sewage discharge under various environmental conditions. The design of SDR 35 pipe fittings not only takes into account the fluid mechanics performance, but also meets the pressure bearing, tensile strength and pressure resistance requirements of the pipe. Therefore, they usually have high strength and can cope with pressure fluctuations in daily life.
Structure of SDR 35 sewer fittings
The structure of SDR 35 sewer fittings varies according to their functions and usage occasions, but usually has the following main components:
1. Appearance structure: The appearance design of SDR 35 fittings is usually simple, which is convenient for installation and connection. Its main feature is that the connection part of the fitting usually has a groove or socket design, which can be tightly docked with the socket part of the pipe to achieve a sealed connection.
2. Sealing ring: In order to ensure the watertightness of the pipe connection, SDR 35 fittings are usually equipped with rubber sealing rings. This sealing ring ensures that the joint between the pipe and the fitting will not leak or leak. The material of the sealing ring needs to have good elasticity and weather resistance, and can maintain a stable sealing effect during long-term use.
3. Reinforcement ribs: In the design of some SDR 35 fittings, reinforcement ribs may be added to improve the compressive and impact resistance of the fittings. Reinforcement ribs can effectively improve the structural strength of the fittings, enabling them to withstand greater external forces.
4. Wall thickness to outer diameter ratio: SDR 35 pipe fittings have a wall thickness to outer diameter ratio of 35 according to the SDR (standard outer diameter ratio) requirements. The wall thickness is relatively thin, but it can meet the strength and toughness required by general sewer drainage systems.
Application areas
SDR 35 sewer pipe fittings are widely used in sewer drainage systems, especially in sewage, rainwater discharge and urban sewage treatment. Specific applications include the following aspects:
Sewage pipe system: In urban sewage treatment systems, SDR 35 pipe fittings are often used to connect sewer pipes, sewage collection pipes and discharge pipes. These pipes need to bear the pressure and corrosion of wastewater flow for a long time, and SDR 35 pipe fittings can meet this demand well with its corrosion resistance and durability of PVC material.
Rainwater drainage system: SDR 35 pipe fittings are also widely used in rainwater collection and discharge systems. For example, in the rainwater drainage pipe system, SDR 35 pipe fittings such as 5-way, tee and elbow are used to connect pipes in different directions to ensure that rainwater can flow smoothly to the predetermined discharge area.
Residential and commercial building drainage system: SDR 35 pipe fittings have been widely used in the drainage system of buildings, especially in the sewage and wastewater pipe systems of residential and commercial buildings. Through these pipe fittings, the drainage pipes inside the building can be smoothly connected to the external sewer system.
Industrial sewage discharge system: sewage generated in many industrial production processes needs to be treated and discharged through a special sewage pipe system, and SDR 35 pipe fittings are also widely used in such systems. Especially in places with serious pollutant emissions such as chemical plants and food processing plants, SDR 35 pipe fittings can effectively prevent corrosion and leakage problems in the pipeline system under harsh environments due to their corrosion resistance.
Advantages
1. Strong corrosion resistance: SDR 35 pipe fittings are made of polyvinyl chloride (PVC), which has excellent acid and alkali resistance and corrosion resistance, and can work in chemical corrosion environments for a long time without damage. This makes it particularly suitable for treating sewage, chemical wastewater, etc.
2. Easy installation: Due to its good processability and lightness, the installation of SDR 35 pipe fittings is very simple. Most pipe fittings adopt a plug-in design, and construction workers only need to simply insert and rotate to complete the connection, reducing the difficulty and time of construction.
3. High economy: PVC material itself has a low production cost, coupled with its simple construction and convenient transportation, SDR 35 pipe fittings are more economical than other material pipe fittings.
4. Long-term stability: SDR 35 pipe fittings can withstand the operating pressure and external load of the pipeline system for a long time, and are not prone to leakage, aging or damage, and have a long service life.
5. Strong pressure resistance: Although the wall thickness of SDR 35 pipe fittings is relatively thin, its design can maintain good stability when subjected to conventional working pressure, meeting the pressure requirements of sewer pipes.
As a commonly used pipe connection component, SDR 35 sewer pipe fittings have been widely used in modern urban drainage, sewage treatment, rainwater discharge and other systems due to their good physical and chemical properties. They are corrosion-resistant, pressure-resistant, easy to install, and highly economical, and are particularly suitable for use in sewage and wastewater discharge systems. With the continuous development of urban infrastructure construction, SDR 35 sewer pipe fittings will continue to play an important role in the construction of future pipeline systems.
