Steel-Tube RTP Pipe

Steel-Tube RTP Pipe

Product Introduction:

Our steel Tube RTP (Reinforced Thermoplastic Pipe) offers a superior combination of strength, drability, and corrosion resistance. This innovative pipe is manufactured through a multi-layer composite process that completely encapsulates a steel pipe within two layers of thermoplastic material. The unique jointesign ensures that the metal

pipe has no direct contact with the conveyed medium, providing exceptional performnce and longevity.

Typical features of Steel tube RTP

Superior Strength: The embedded steel pipe provides exceptional strength, enabling the pipe to withstand high pressures and demanding operating conditions.

Corrosion Resistance: The thermoplastic outer and inner layers offer excellent corrosion resistance, protecting the steel pipe and extending the pipe's service life.

Abrasion Resistance: The combination of steel and thermoplastic materials(HDPE/UHMWPE/POE) provides superior abrasion resistance, making it ideal for handling abrasive slurries and solids.

Leak-Proof Joints: The specialized joint design ensures a leak-proof connection, preventing any leakage or

contamination of the conveyed medium.

Quick Installation: The installation only needs two bolts&Nuts, one connection finish in few minutes.

Long Service Life: The combination of materials and construction techniques results in a pipe with a long service life, reducing maintenance costs.

Versatility: Suitable for a wide range of applications, including oil and gas, water supply, chemical processing, and

mining

Unique Construction

Multi-Layer Composite: The pipe consists of three layers: an inner thermoplastic tube layer, a steel pipe, and an outer thermoplastic layer.

Complete Encapsulation: The steel pipe is completely encapsulated by the thermoplastic layers,

protecting it from corrosion and providing a smooth inner surface.

Specialized Joint: The joint design ensures a watertight seal and prevents any contact between the metal pipe and the conveyed medium.

Applications

Oil and Gas: For subsea pipelines, onshore gathering systems, and flowlines.

Water Supply: For high-pressure water transmission and distribution systems.

Chemical Processing: For handling corrosive and abrasive fluids.

Mining: For slurry transportation and dewatering applications.
