API 5CT Tubing Pipe is a special pipe for oil and gas production run inside the oil well casing, following the API 5CT international standard, and is the "channel" for transporting oil and gas from the formation to the ground. The product has high strength, high sealing performance, wear resistance and corrosion resistance, and can withstand the erosion of high pressure, high temperature and complex media (crude oil, natural gas, formation water) downhole. It is divided into plain-end tubing, upset tubing and other types, adapting to different oil production processes (natural flow production, mechanical oil production, etc.). The steel grades cover J55, N80, P110, etc., and can be customized with specifications according to well depth, output and downhole working conditions to ensure efficient exploitation and stable transportation of oil and gas. It is the core consumable for oil and gas production operations.

API 5CT Casing Pipe is a core protective pipe run into the well after oil well drilling, which strictly complies with the API 5CT standard and is divided into surface casing, intermediate casing, production casing and other types. Its core function is to fix the wellbore, isolate different formations (such as oil layer, water layer, gas layer), prevent wellbore collapse and formation fluid channeling, protect wellbore safety, and lay the foundation for subsequent oil and gas production operations. The product adopts high-toughness and collapse-resistant steel, and can be customized with different steel grades (such as J55, K55, N80, P110, etc.) and specifications according to well depth, formation pressure and geological complexity, adapting to various types of oil wells such as vertical wells, deviated wells and horizontal wells. It is the "protective shell" for the safe and stable production of oil and gas wells.

API 5L Line Pipe is a core transportation pipe for the oil and gas industry, manufactured in strict accordance with the API 5L international standard. It is mainly used for long-distance transportation of crude oil, natural gas, refined oil and other industrial fluids on the ground and underground. The product adopts high-strength carbon steel and alloy steel pipes, with excellent pressure resistance, impact resistance and corrosion resistance. It can be customized with different materials (such as A106, X42, X52, X65, etc.) and specifications according to the transportation medium, pressure level and laying environment (land, seabed, desert, etc.) to meet different working condition requirements. As the "aorta" of oil and gas transportation, it is widely used in long-distance pipelines, urban gas pipelines and oil and gas field gathering and transportation systems to ensure efficient, safe and stable transportation of media.

3PE Coated Pipe is a special anti-corrosion oil transmission pipe processed with API 5L line pipe as the base material and a three-layer anti-corrosion structure of "epoxy powder + adhesive + polyethylene" on the surface. This product perfectly combines the high-strength pressure resistance of the base material with the excellent anti-corrosion performance of the 3PE coating, which can effectively resist soil corrosion, chemical medium erosion and underground stray current interference, and greatly extend the service life of the pipeline (usually up to 30-50 years). It is mainly used in buried oil and gas pipeline projects, especially suitable for complex geological environments with high humidity, salt and alkali, and strong corrosion. It is the preferred anti-corrosion solution for long-distance buried pipelines, which can significantly reduce pipeline maintenance costs and ensure the long-term stable operation of the transportation system.
