304 stainless steel lined PO pipe tee elbow with variable diameter

Description :

304 stainless steel lined PO pipe tee elbow with variable diameter

304 stainless steel lined PO pipe is made of 304 stainless steel pipe as the substrate, lined with thermoplastic pipe with excellent chemical stability, and formed by cold drawing composite or rolling molding. The lining thickness is: DN25-DN40, thickness 2.0mm; DN50-DN80mm, thickness 2.5mm~3mm; DN100-DN150mm thickness 3.0mm~3.5mm; DN200-DN400mm with a thickness of 4.5-5.0mm8mm combines the mechanical properties of steel pipes with the corrosion resistance of plastic pipes; Gradually recognized by customers for many years and purchased in bulk, our company is surrounded by two major logistics parks with convenient transportation and timely delivery. We welcome new and old customers to inquire.

The 304 stainless steel lined PO pipes and fittings we produce are mainly divided into 304 stainless steel lined PO pipe elbows, 304 stainless steel lined PO pipe equal diameter tees, 304 stainless steel lined PO pipe reducers, 304 stainless steel lined PO pipe reducers, 304 stainless steel lined PO pipe tees, 304 stainless steel lined PO pipe fittings, and so on. They are all fittings that are connected to the 304 stainless steel lined PO pipe straight pipes and can be mass-produced. Please inquire if you need them.

304 stainless steel lined PO pipe has good characteristics:

1. Corrosion resistance, including acid, alkali, salt, etc;

2. Insulation properties, not susceptible to electrochemical corrosion;

3. It can be used within a wide temperature range of -20 to 105 ℃;

4. Smooth surface with low friction coefficient, excellent resistance to foreign objects and wear.

Process flow of 304 stainless steel lined PO pipe straight pipe:

1. Welding: Cut the steel pipe according to the customer's required size, and then weld the prepared flange and steel pipe internally and externally.

2. Grinding, sandblasting and rust removal: Polish the welding part between the steel pipe and the flange; Then carry out sandblasting for rust removal;

3. Heating steel pipes: uniformly heating them in a medium frequency furnace to reach a predetermined temperature;

4. Filling part: Inner lining thickness, calculate the required materials, and fill the plastic powder into the pipeline;

5. Hot rolling molding part: Use a rolling molding machine to apply centrifugal rolling coating to the inner wall of the pipeline;

6. Rust removal and painting. After the pipeline cools down, the outer pipe is rust removed and painted with anti-corrosion paint. After drying, it is the finished product.

7. Electric spark detection of pipe quality.

Inspection and inspection criteria for 304 stainless steel lined PO pipes:

1. Steel pipe material: mainly inspect the appearance, size, tolerance, and inspection methods: tape measure, vernier caliper;

2. Inner lining material: High frequency spark detection is used, and there should be no breakdown phenomenon. The detection voltage is ≥ 12KV, and the moving speed inside the plastic lining layer is less than 100mm/s, moving at a constant speed;

3. Plastic powder materials: comply with relevant standards and regulations;

4. Flanges, elbows, and three-way reducers are mainly inspected for dimensions and tolerances; Use a vernier caliper for inspection.
