PVC Drainage pipe

PVC Drainage pipe is mainly used in the construction of drainage systems and is suitable for wastewater discharge in households, industries and commercial places. PVC Drainage pipe plays an important role in modern drainage systems with its unique advantages.

Production process

1. Raw material preparation: The main raw material of PVC Drainage pipe is polyvinyl chloride (PVC) resin, and an appropriate amount of stabilizer, lubricant, filler, color enhancer, etc. will be added to ensure the physical and chemical properties and durability of the pipe.

2. Extrusion molding: The mixed raw materials are extruded and molded by a plastic extruder. This process involves heating the raw materials to a molten state and then extruding them through a mold to form the initial shape of the pipe.

3. Cooling: The extruded pipe undergoes a cooling process, usually by a vacuum pump, to ensure the stability and quality of the pipe.

4. Cutting: At the end of the assembly line, a ring cutter is used to cut the cooled pipe into standard lengths to meet different usage requirements.

5. Quality inspection: The cut pipe will undergo quality inspection (QC) to ensure that it meets quality standards. Qualified PVC pipes will be sent to the warehouse for final inspection, labeling, and finally sold on the market.

Advantages

1. The surface hardness and tensile strength of PVC Drainage pipe are excellent, which ensures the high safety factor of the pipe, can withstand greater pressure, and ensure the stability of the pipeline system.

2. It has good anti-aging performance, long normal service life, can resist the influence of various natural environmental factors, and ensure long-term stable use.

3. PVC Drainage pipe has excellent corrosion resistance to inorganic acids, alkalis, salts and other substances, and is particularly suitable for industrial sewage discharge and transportation.

4. Its friction coefficient is small, the water flow is smooth, it is not easy to block, and the need for maintenance work is reduced.

5. PVC Drainage pipe has a small linear expansion coefficient, small deformation affected by temperature, good anti-freezing performance, and adapts to various climatic conditions.‌‌

JUNNUO PVC drainage pipe is a perfect solution for municipal engineering system and urban water supply and drainage system. With the size range of DN 20 - 1000mm, and the performance conforms to ISO4435 standard and other national certification standards.

Brief details:

The strength and stiffness of low-pressure underground sewage and PVC-UH pipes for drainage are improved, and the bearing capacity of the system is maximized within a certain budget.

• Do not be affected by sewer acid and alkali, and avoid alkali and acid corrosion of soil.
• Stable performance, can effectively prevent corrosion and adapt to external current soil conditions, without lining packaging, coating and cathodic protection.
• Wear resistance, tensile resistance and impact resistance are much better than common pipeline materials.
• Smooth inside of the pipe for a long time, while maximizing the capacity of the system, can save pumping costs.
• Light weight could save installation cost. Cutting can be done in the site with a electric saw or ordinary hand saw, without using expensive or complicated machinery.
• Ring lock washer insider of the pipes, which eliminates the requirement of welding for old PVC drainage pipes in site.
• Elastic gaskets provide excellent sealing and protect the entire section from impact, vibration, soil movement, expansion and contraction in deep trenches.
• Simple push-in connections provide quick and easy installation without the need for on-site mixing and the use of cement.
• The connection shall be well sealed under normal working conditions.
