Overview of Composite and Reinforced Pipes

The document provides technical specifications and applications for various types of composite and reinforced pipes used primarily in oil, gas, mining, and water industries.

1. Pipe Types and Specifications

• Flexible Reinforced Thermoplastic Pipes (RTP): Comply with API 15S standards, spoolable in coil form, with multiple layers of fiberglass reinforcement. Working pressure up to 5 MPa, pipe inner diameter ranges from 2 to 8 inches.
• Steel Reinforced Polyethylene Pipe (SRTP): Diameter range DN50 to DN630 mm, pressure ratings from PN10 to PN16. Connections use electric fusion fittings. Suitable for rigid installations, negative pressure environments, and fire retardation applications.
• HDPE Composite Mining Pipe: Diameter range DN50 to DN1200 mm, pressure ratings from PN10 to PN35. Connections also use electric fusion fittings. Designed for water, slurry, and mining applications.

2. Material and Construction Features

• Use of bonded fiberglass layers for reinforcement in RTP to enhance strength and flexibility.
• Steel reinforcement in polyethylene pipes to improve pressure resistance and durability.
• Special abrasion-resistant liners in HDPE pipes to extend service life, especially in slurry and abrasive environments.

3. Performance and Application Highlights

• Working pressures up to 20 MPa for certain pipe types.
• Pipe diameters cover a broad range from 50 mm up to 1200 mm, accommodating various industrial needs.
• Applications include oil and gas transport, mining slurry conveyance, water supply, and environments requiring fire retardation and negative pressure resistance.

4. Connection and Installation

• Electric fusion fittings are the standard connection method for both SRTP and HDPE composite pipes, ensuring secure and reliable joints.
• Spoolable pipe designs facilitate easier transportation and installation, especially for flexible RTPs.

5. Additional Equipment and Services

• High-pressure end crimping machines and electric fusion fitting equipment are available to support pipe installation and maintenance.
• Contact information for suppliers and technical support is provided, indicating a global supply chain with presence in China, Africa, and South America.

Summary

This document outlines the technical parameters, construction details, and application areas for advanced composite and reinforced pipes. Key features include compliance with industry standards (API 15S, DNVGL-RP-F1), a wide range of diameters and pressure ratings, abrasion-resistant liners, and specialized connection methods. These pipes are designed to meet demanding conditions in oil, gas, mining, and water industries, offering enhanced durability, flexibility, and ease of installation.
