Types Of Pp Pipe

PP-H (Polypropylene Homopolymer)

High stiffness, excellent heat resistance, used in industrial and chemical applications.

PP-B (Polypropylene Block Copolymer)

Impact-modified version with ethylene blocks, suited for cold-water or outdoor installations.

PP-R (Polypropylene Random Copolymer)

Modified for high-pressure and hot-water applications, widely used in plumbing.

How To Connect The PP Pipe

Hot melt connection

Hot melt joining is a method of melting the joint parts of PP pipes by heating, and then quickly fitting them together, cooling and curing to form a firm connection. Hot melt connection has the advantages of reliable connection, good durability and easy construction, and is one of the most commonly used connection methods for PP pipes. When making a hot melt connection, it is necessary to use a special hot melt welder and follow the prescribed operating procedures.

Socket connection

Socket connection is a connection method in which one end of a PP pipe is inserted into the socket of another pipe, and then fixed together by methods such as heat or adhesive. The socket connection has the advantages of simple construction and good durability, and is suitable for some pipe connections with large diameters. It should be noted that socket connections have high requirements for the size of the pipe, and precise fit is required.

Flange connection

Flange connection is a connection method in which PP pipes are welded with flanges or bolted together. The flange connection has the advantages of firm connection and good pressure resistance, and is suitable for piping systems that need to withstand large pressures. It should be noted that the flange connection needs to use a special flange, and the welding quality has a great impact on the reliability of the connection.

Manufacturing Process of PP Pipe

Raw Material Feeding
High-grade polypropylene resin is blended with UV stabilizers, pigments, and performance additives in a controlled environment.

Extrusion
The compounded material is melted and extruded through a custom-designed die head to form a continuous cylindrical tube.

Sizing and Calibration
In the calibration tank, vacuum sizing ensures consistent inner and outer diameters according to ISO/DIN standards.

Cooling
The hot extrudate passes through multi-stage water baths for gradual cooling, preventing stress cracks.

Cutting

An automatic cutter slices the pipe to preset lengths, typically 4m–6m, with precise edge trimming.

Inspection

Dimensional checks, pressure burst tests, and visual inspections ensure uniform wall thickness and surface finish.

Marking and Packaging

Each PP pipe is marked with manufacturing data, size, pressure rating, and the SW brand code, then packaged for delivery.

Applications of PP Pipe

Plumbing and Water Distribution

PP-R pipes are widely used in domestic and commercial hot and cold water systems. Their heat resistance makes them an excellent replacement for copper and steel.

Chemical and Industrial Fluid Transport

PP-H and PP-B variants are used to convey aggressive fluids such as acids, alkalis, and solvents in chemical processing plants.

HVAC and Cooling Systems

Thanks to its resistance to temperature cycling, PP pipe is used in chilled-water and HVAC systems, ensuring leak-free and corrosion-resistant flow.

Food and Beverage Processing

PP pipes meet food-grade requirements for hygienic transport of water, milk, and beverages, supported by their non-toxic composition.

Wastewater and Drainage

Due to their smooth internal surface and resistance to fouling, PP pipes are used in municipal sewage systems and industrial wastewater networks.

Electrical and Cable Conduits

As a lightweight, insulating material, PP pipe serves as protective conduit for power cables in high-humidity environments.

FAQ

Q: What is the full form of PP pipe?

A: Polypropylene Pipes. Polypropylene (PP) is a member of the polyolefin family and is used for conveyance of acids, alkalies, organic solvents, and even pure water. PP pipes and fittings are ductile at ambient temperature and demonstrate good impact strength.

Q: How is PP made?

A: Polypropylene is produced by the chain-growth polymerization of propene: The industrial production processes can be grouped into gas phase polymerization, bulk polymerization and slurry polymerization. All state-of-the-art processes use either gas-phase or bulk reactor systems.

Q: What is the specification of polypropylene pipe?

A: Polypropylene Pipe shall be manufactured from a Group 1, Class 2 Beta Polypropylene Homopolymer material manufactured to SDR 11 dimensions with a pressure rating of 150 psi when measured at 68°F (20°C). Pipe internal surface finish shall be Ra ≤ 39.4µin. Pipe shall be manufactured in sizes from ½” through 16”.

Q: What is the roughness of PP pipe?

A: Minimal resistance to water flow, as the inner wall of the PP-R pipe has a roughness of only 0.007 mm, significantly less than that of metal pipe.
