PP Pipe -Hualin Pipe Technology

PP Pipe

PP pipes can transport drinking water, domestic water and hot water for heating. They are resistant to high temperatures and the hot melt connection has good sealing to avoid the risk of leakage.

PP Pipe Manufacturer in China

‌PP pipe is a pipe made of polypropylene. Polypropylene is a semi-crystalline thermoplastic. Its excellent chemical corrosion resistance and high temperature stability make it very suitable for piping systems in the chemical industry. PP pipe has high tensile strength, ensuring its durability and reliability in various applications.

Key Features of HUALIN PP Pipe

JUNTONG PP pipe has excellent chemical stability, can withstand acid, alkali and a variety of organic solvents, and is suitable for chemical industry, water supply and drainage and other fields. It has a wide operating temperature range (-20℃ to 95℃), low thermal conductivity, and can effectively reduce heat loss. The weight of PP pipe is only 1/8 of that of metal pipe, and it is easy to install. The hot melt connection ensures zero leakage at the interface. The material is non-toxic and odorless, meets the drinking water standards, and the inner wall is smooth and not easy to scale, with low fluid resistance. In addition, PP pipe has outstanding antifreeze performance (no cracking at -20℃), a service life of up to 50 years, and a high comprehensive cost-effectiveness. It is an environmentally friendly choice to replace traditional metal pipes.

HUALIN PP Pipe Applications Explored

PP pipes are widely used and are suitable for various applications such as construction, agriculture and industry. In the construction field, PP-R pipes are the core pipelines for hot and cold water supply. They not only ensure the safe transportation of drinking water, but also withstand hot water circulation. The hot-melt connection method ensures long-term use without leakage. Its corrosion resistance also makes it the first choice for drainage and sewage systems, reducing water flow resistance and reducing the risk of blockage. In the industrial field, PP pipes are widely used in the transportation of chemical raw materials due to their tolerance to chemical media such as acid and alkali solutions and organic solvents. In the electronic semiconductor industry, high-purity PP pipes are essential pipelines for the transportation of ultrapure water and clean fluids to avoid metal ion pollution. In the agricultural and environmental protection industries, PP pipes are used in farmland drip irrigation and sprinkler irrigation systems. Their anti-ultraviolet aging characteristics enable them to adapt to outdoor environments. In the field of sewage treatment, it undertakes the task of collecting and transporting sewage, effectively resisting the corrosion of microorganisms and organic matter in sewage. In addition, in the food and pharmaceutical industry, PP pipes that meet hygiene standards are used to transport food raw materials, liquid medicines, etc.; while silent PP pipes are used in noise-sensitive places such as hospitals and residences to solve noise problems in drainage systems, fully demonstrating the diversity of their applications.

FAQ

How to install and use PP pipes correctly?

The following is a comprehensive guide to the proper installation and use of PP pipes:

1.Cutting process ‌
Use a special cutter to cut the pipe vertically to ensure that the cut is smooth and burr-free. After cutting, remove the debris and polish it with sandpaper.
2.Clean the connection surface ‌
Wipe the pipe end and the pipe fitting socket with 95% alcohol or special cleaning agent to remove oil and impurities.
3.Hot melt connection (mainstream method) ‌
Preheating equipment ‌: Heat the hot melter to 200±5℃ (adjust the temperature according to the thickness of the pipe wall).
‌Heating and docking ‌: Insert the pipe and the pipe fitting into the heating die head at the same time. The heating time is controlled according to the pipe diameter (for example: DN20 pipe is about 5 seconds), quickly pull out without rotation and insert it vertically into the socket to form a uniform flange
Cooling and shaping ‌: Maintain the docking pressure until cooling (about 3 minutes), and it is forbidden to move the pipe during this period
Mechanical connection (applicable to silent pipes) ‌
‌Screw-mouth gland type ‌: After the pipe is inserted into the pipe fitting, it is sealed with ABS locking ring and silicone ring, and the gland is tightened.
‌Socket and spigot flexible connection‌: The insertion depth needs to be controlled (≤8mm in summer, ≤12mm in winter) to avoid leakage due to thermal expansion and contraction.
