Composite Pipe by Baker Hughes is a continuous, spoolable, reinforced thermoplastic pipeline system. Its non-metallic design and manufacturing process provides high-pressure, corrosion-free operation.
You can use composite pipe in all typical oil and gas applications, including:
Other industries, like mining, have used Composite Pipe by Baker Hughes to handle acidic and erosive applications.
We manufacture our composite pipes, couplings, and fittings in our state-of-the-art facility in Houston, Texas. The facility produces multi-layer coextruded liner pipe, tape line winding, and cover layer extrusion.
Onsite silos store raw materials, which eliminates downtime. And it allows for efficient production planning. The facility also houses its chiller water system, giving precise control of the pipe production cooling process.
Besides rapid development of pipe products and specialty testing, our site supports research and development staff and equipment. This proximity allows for fast communication between development and production operations.
Baker Hughes designs its composite pipe according to API Specification 15S: Spoolable Reinforced Plastic Linepipe. The pipe includes:
Our composite pipe is available in sizes from 4” to 8” and for pressures from 750 psi to 1500 psi. Reel lengths go up to 2,050 feet, depending on pipe size and reel capacity.
Your temperature requirements and chemical compatibility determine the pipe liner and cover materials. HDPE handles temperatures up to 150°F (65°C), and PERT covers temperatures up to 180°F (82°C). Both materials are PE4710 per ASTM D3350. We can also manufacture the liner with a PA or PPS barrier layer for more chemical and permeation resistance.
We deliver consistent quality throughout our composite pipe’s design, qualification, manufacture, and installation.
Quality assurance starts with inline sensors that monitor the manufacturing process. Multiple sensors track the various stages of pipe manufacture. The sensors check several process parameters. Machine intelligence identifies deviations and automatically corrects them, minimizing manufacturing defects.
Offline sampling and destructive testing assure that our product quality meets your challenging application needs. These include burst, fiber tensile break tests, and cross-sectional inspections of the laminate and liner.
Our Quality Management System is compliant with the requirements of ISO 9001 and API Q1. A Certificate of Quality Assurance is available before shipment. All it takes is a simple request. The certificate summarizes the results from all quality assurance tests.
Our proprietary composite pipe end fittings and couplings take just 15-30 minutes to install. These robust and reliable fittings have a stem and ferrule design. You can install them with a single-step swaging process.
The process compresses the ferrule into plastic deformation and anchors the fitting to the pipe. This creates a leak-proof seal between the inner layer of the pipe and the stem of the fitting.
Our end fittings use NPT threads, API/ASME Lap Flanges, or weld-prepared (beveled) ends for connections to surface equipment or infrastructure. We construct connection points, like tees and wyes, from several composite pipe end fittings. Depending on your requirements, we can preconstruct these fittings or construct them in the field.
Our composite pipe end fittings and couplings meet the requirements of API 15S. The requirements include an elevated temperature test for long-term performance. They also include a temperature cycling test for suitability across the installation and operating temperature ranges. Our composite end fittings and couplings match the pipe size, temperature, and pressure ratings.
Composite pipe end fittings and couplings use the following materials:
Depending on your fluid composition and corrosion resistance requirements, we have different coating options available.
Corrosion of metallic materials is a complex phenomenon. Many factors drive corrosion, including fluid composition, CO2, H2S, water content, chloride concentration, temperature, and pressure. Our Application Engineering team can help you choose a material based on in-house testing, published literature, and industry standards.
Qualification regression testing at the maximum rated temperature per API 15S determines pressure rating or long-term hydrostatic strength.
The chart below shows the rated pressures and sizes for composite pipes determined by regression testing and product variant tests. The minimum specified design life of the pipe is 20 years.
The Maximum Operating Pressure (MOP) is rated using industry-standard design factors for all fluid types. It does not require a derate for any standard oilfield service, including hydrocarbons, gas, and produced water.
This additional barrier also prevents absorption and breakdown of the pipe from acids, BTEX’s, and other light hydrocarbons. The liner is fully compatible with methanol and alcohols used to prevent freezing in winter climates.
Our design isolates the reinforcement layer from the bore fluid and protects it from external hazards by the jacket. Because of this unique feature, the strength of Composite Pipe by Baker Hughes is not affected by most chemicals. However, our engineering teams can explain the compatibility of specific chemicals to you.
All pump types produce pressure variations. Pressure cycling caused by different pumps or on/off cycles generally doesn’t affect composite pipe. The glass-fiber thermoplastic tape reinforcement design withstands cyclic loading and abrasion caused by pressure and external movement or vibration. We recommend using properly sized pulsation dampeners if you’re using high-pressure positive displacement pumps, such as triplex or duplex.
If you anticipate high vibration, your pipeline should be restrained from unwanted movement and isolated from objects that could abrade the pipe over time. Contact Baker Hughes Engineering for guidance about any pressure cycles or vibration concerns.
Composite pipe has a smooth bore which produces favorable flow and reduced frictional losses compared to other pipe materials like steel.
Because we use non-metallic pipe materials, the roughness will not change due to corrosion. This means you’ll see minimal changes to the flow capabilities of the line over its useable lifetime.
The roughness value of our pipe for friction loss calculations is 0.00006 in (0.015 mm). The graph below shows pressure drop comparisons for four-, six-, and eight-inch composite pipes over varying flow rates for water and gas applications.
Erosion and abrasive flow generally don’t affect composite pipe. Our non-metallic materials experience less abrasive loss than steel under the same flow conditions. Many variables can change the severity of erosive flows, such as particle size and flow velocity. However, maintaining a sufficient flow velocity keeps suspended particles from dropping out of the carrying fluid. We recommend testing the specific operating conditions for compatibility where severe erosion is a concern.
