Reinforced Thermoplastic Pipe (RTP): Specifications and Applications for Harsh Industrial Environments

Reinforced Thermoplastic Pipe (RTP): Specifications and Applications for Harsh Industrial Environments

Reinforced Thermoplastic Pipe (RTP) is a composite pipeline solution that combines an inner and outer thermoplastic layer with one or more reinforcement layers, designed to transmit fluids under high pressure in demanding environments. ZYfire Hose Corporation, established in 2000 and publicly listed on the Beijing Stock Exchange, manufactures RTP for the oil and gas and mining industries. This article presents the technical specifications, material options, and typical applications of ZYfire’s RTP, based on verified product data and company information.

Industry Challenge

Traditional steel pipes used in oil fields, offshore platforms, and mining operations often suffer from internal corrosion, heavy weight, and complex installation requirements. Frequent fittings and joints create leak points, while the rigid nature of steel complicates routing in confined spaces. These factors increase total lifecycle cost and operational risk. RTP addresses these challenges through its corrosion-resistant polymer materials, flexibility, and long coil lengths that significantly reduce the number of connections.

Background: The Rise of Reinforced Thermoplastic Pipe

In recent decades, the oil and gas and mining sectors have increasingly adopted RTP as an alternative to carbon steel. The combination of thermoplastic layers with reinforcing fibers or tapes delivers pressure ratings comparable to steel while offering chemical resistance and lower weight. Standards such as API 15S (a specification from the American Petroleum Institute) have established quality benchmarks for RTP design and testing. ZYfire’s RTP is designed to meet API compliance, ensuring reliable performance in critical applications.

ZYfire RTP Product Specifications

ZYfire offers a Reinforced Thermoplastic Pipe with the model designation “2” 3500PSI O.D:79.8. The nominal pressure rating is 3500 PSI, and the outside diameter is 79.8 mm. Each coil has a single length of 920 meters, with reel dimensions of 3700 × 1200 mm. The reel weight is 1200 kg, and the full plate weight is 5524 kg. The pipe is manufactured in four reinforcement categories:

• Polyester Fiber tape-reinforced RTP
• Steel Wire tape-reinforced RTP
• Aramid Fiber tape-reinforced RTP
• Glass Fiber tape-reinforced RTP

The inner and outer layers are made of HDPE (High-Density Polyethylene) and PE-RT (Polyethylene of Raised Temperature), with optional additives for UV resistance and antioxidant protection. The choice of reinforcement material depends on the required pressure rating, temperature, and chemical exposure of the specific application.

Step-by-Step: Selecting the Right Reinforcement for Your Application

1. Identify operating pressure and temperature: All ZYfire RTP variants are rated to 3500 PSI. If higher pressure is needed, steel wire or aramid fiber reinforcement may provide additional margin.
2. Assess chemical exposure: For oil with high aromatic content, PE-RT inner layer is recommended. HDPE is suitable for water and standard hydrocarbon services.
3. Consider flexibility requirements: Polyester and glass fiber tapes offer good flexibility for reeling and installation in curved paths.
4. Verify environmental conditions: If the pipe will be exposed to UV or oxidation, specify the optional UV and antioxidant additives.
5. Confirm compliance with project standards: ZYfire’s RTP is designed to comply with API standards, suitable for projects requiring explosion-proof, corrosion-resistant, and high-pressure-tolerant piping.

Use Cases

ZYfire’s RTP is deployed in mining and oil and gas operations that run in 24/7 continuous mode. Typical application scenarios include fluid transmission systems in the United Arab Emirates, Argentina, Australia, Bahrain, Canada, Kuwait, Liberia, and Libya. The 920-meter coil length minimizes field fittings, reducing potential leak points and installation time. The pipe is designed to be corrosion-resistant, explosion-proof, and capable of withstanding high pressure up to 3500 PSI while meeting API standards. It must be used with fluid transmission equipment.
