Import Api 5l Line Pipe With 3pe/3lpe Coating — Buy in wholesale FOB from Supplier in China

API 5L line pipe with 3PE or 3LPE coating from Beijing Metleader Pipeline Technology Inc. is a carbon steel pipe designed for oil and gas transmission, featuring a three-layer polyethylene coating for corrosion resistance. The pipe meets API 5L and ISO 3183 standards, with grades ranging from X42 to X70, and is available in diameters from 0.5 inches to 24 inches for seamless variants. Wall thicknesses span SCH 10 to SCH 160, and lengths are offered in 20 FT or 40 FT, or customised to project requirements. The coating system extends service life in buried or offshore applications, where exposure to moisture and abrasive soils is common. End types include beveled or plain, with protection via plastic or iron caps to prevent damage during transit. This pipe is engineered to handle high-pressure transmission, with the coating providing a barrier against chemical and electrochemical degradation. The seamless and welded options cater to different pressure and structural demands, while the beveled ends facilitate welding for pipeline assembly. Beijing Metleader Pipeline Technology Inc. supplies these pipes with end protection and surface treatments such as natural, varnished, or black painting, in addition to the 3PE/3LPE coating. This product is primarily used in long-distance pipelines for petroleum, natural gas, and water, where durability and resistance to external corrosion are critical. Buyers typically include energy companies, pipeline contractors, and infrastructure developers sourcing for cross-country or subsea projects. Trade terms such as incoterms, packaging, and lead times are confirmed with the supplier, as these are tailored to the project scale and logistics requirements.

The carbon steel material adheres to API 5L specifications, with grades X42 through X70 offering varying tensile strengths and yield points to suit different pressure classes. The 3PE coating consists of three layers: an epoxy primer for adhesion, a copolymer adhesive, and a polyethylene topcoat for UV and moisture resistance. Typical industry standards for such pipes include hydrostatic testing to verify pressure integrity, with common test pressures ranging from 75 to 95% of the specified minimum yield strength. The seamless variant is often preferred for smaller diameters where precision and uniformity are paramount, while welded pipes are used for larger diameters and cost-effective production. Standard tolerances for outer diameter and wall thickness are maintained within API 5L limits, ensuring compatibility with fittings and joints. The pipe’s surface finish is critical for coating adhesion, with typical roughness values (Ra) of 25 to 50 micrometres for optimal bonding. Additional treatments such as FBE (fusion-bonded epoxy) or cladding are available for specialised corrosion resistance, though 3PE remains the most common for buried applications.

Applications span onshore and offshore pipelines, where the pipe’s resistance to corrosion and mechanical stress is essential. Cross-country pipelines for natural gas or crude oil often specify 3PE-coated pipes for their balance of cost and performance, while offshore platforms may require additional cathodic protection. Refineries and petrochemical plants use these pipes for internal process lines, where high-pressure and temperature conditions demand robust materials. The pipe’s versatility extends to water transmission projects, particularly in regions with aggressive soil conditions. Buyers should confirm the specific grade, coating type, and dimensional tolerances to match their project’s engineering specifications. Beijing Metleader Pipeline Technology Inc. provides customisation for length, end type, and coating, ensuring alignment with the buyer’s technical and logistical needs.
