SDR (Standard Dimension Ratio) is a standard dimension ratio used to describe the proportional relationship between the wall thickness and the outer diameter of PVC pipes. SDR 35 pvc pipe means that its wall thickness is relatively thin and the ratio of outer diameter to wall thickness is large. The following is a detailed introduction:
SDR 35 pvc pipe is a pipe made of polyvinyl chloride (PVC) material with excellent physical and chemical properties. It is usually used to transport fluids such as tap water, drainage, agricultural irrigation, etc., and is widely praised for its corrosion resistance, light weight, and easy installation.
1. Strong corrosion resistance: SDR 35 pvc pipe has excellent chemical corrosion resistance, can resist the erosion of various chemical substances, and is suitable for a variety of harsh environments.
2. Lightweight and high strength: Compared with other materials, PVC pipe has a lower density, but higher strength, and can withstand certain pressure and load.
3. Easy installation: PVC pipes are usually connected by adhesive or rubber ring, which is easy and quick to install, reducing the difficulty and cost of construction.
4. Low water flow resistance: SDR 35 pvc pipe has a smooth inner wall and low water flow resistance, which can efficiently transport fluids and reduce energy consumption.
5. Long service life: PVC pipe has a long service life, generally up to 20-50 years, and low maintenance cost.
The specifications of SDR 35 pvc pipe are usually expressed by its outer diameter and wall thickness. The following are some common specifications (for reference only, the actual specifications may vary depending on the manufacturer and purpose):
Outer diameter range: usually ranges from 20mm to hundreds of millimeters, depending on the use requirements.
Wall thickness: According to the standard dimension ratio of SDR 35, the wall thickness will increase with the increase of outer diameter, but it is relatively thin relative to the outer diameter.
SDR 35 pvc pipe is widely used in the following fields due to its excellent performance and low cost:
1. Civil buildings: indoor water supply and drainage systems of buildings such as houses and apartments.
2. Industrial buildings: water supply, drainage and grey water systems of buildings such as factories and workshops.
3. Urban water supply: urban water supply pipeline system, including buried water supply pipelines and water delivery pipelines.
4. Agricultural irrigation: farmland irrigation systems, such as drip irrigation, sprinkler irrigation, etc.
5. Other industrial uses: fluid delivery pipelines in industries such as chemicals, electricity, and mining.
Choose a regular manufacturer: When purchasing SDR 35 pvc pipe, you should choose a regular and qualified manufacturer to ensure product quality.
Pay attention to the use environment: Although PVC pipes have excellent corrosion resistance and weather resistance, they still need to be used with caution in certain extreme environments, such as high temperature, strong acid and alkali environments.
Correct installation: The installation should be carried out in accordance with the product manual and relevant standards to ensure that the connection is firm and the seal is reliable.
Regular inspection: During use, the pipeline should be regularly checked for damage, leakage and other problems, and timely treatment should be carried out.
In summary, SDR 35 pvc pipe is a pipeline product with excellent performance and low cost, which is widely used in various fields. When purchasing and using, attention should be paid to product quality, use environment, installation method and regular inspection.
