May I ask whether fiberglass-reinforced plastic composite pipes can be used for natural gas transmission pipelines (with moisture)?

It’s better not to use it. I tried using CPVC plastic pipes for catalyst transfer tubes that contained flammable gases such as acetylene, but the tubes exploded after just a few days of use; it was likely caused by static electricity.

What is the purpose? Is it to prevent corrosion?

There are many factors to consider in industrial production; whereas for domestic gas systems, rubber hoses are used at the end

The company currently has an unused buried steel skeleton composite pipe, and it would like to use it for transporting natural gas (with moisture). The required pressure rating is 5.5 MPA, which meets the necessary requirements. The flow rate needed is 3,000 cubic meters per day. We are wondering whether glass fiber reinforced plastic pipes can be used in accordance with the design specifications for natural gas pipelines. If anyone is familiar with these specifications, we would appreciate it if they could provide some information. Thank you

For such high pressure levels, steel pipes are required; you can refer to the Natural Gas Transmission Design Code for more details @ZhizheMing

Medium-pressure gas pipelines can use steel-reinforced polyethylene plastic composite pipes, but they must comply with the specifications outlined in \"Steel-Reinforced Polyethylene Plastic Composite Pipes for Gas Use\" CJ/T 125 and \"Fittings for Steel-Reinforced Polyethylene Plastic Composite Pipes for Gas Use\" CJ/T 126.

Our company is one of the world’s renowned fiberglass-reinforced plastic brands, and we act as the agent in China for FPI’s fiberglass pipe products. The fiberglass pipes and fittings supplied by our company are widely used in industries such as petroleum, chemicals, oil and gas fields, and shipbuilding. Over the years, thanks to its high-quality products, professional services, and highly competitive prices, our company has successfully completed numerous oil and gas field projects both domestically and internationally, earning a solid reputation in the industry as well as the trust of its clients. The pressure you mentioned can be met by glass fiber reinforced plastic pipes, but the selection still requires taking into account specific parameters such as design pressure, design temperature, and pipe diameter.

Please list your company’s technical advantages and engineering projects, and provide evidence for them.
