Pengfa API 5L Seamless Pipe, crafted by a prestigious manufacturer in China renowned for its adherence to the highest standards of engineering excellence, represents the pinnacle of quality and reliability in the industry.
As a proficient manufacturer with expertise in the field, we are pleased to offer you Pengfa API 5L Seamless Pipes, also commonly referred to as Straight Steel Pipes in English. For general purposes, welded pipes are utilized for the transportation of low-pressure fluids. These pipes are constructed from a range of steel grades, including Q195, Q215A, Q235A, and plain carbon Q235B steel, as well as compatible with 0317 standard grade 6012 and 755 mild steel for ease of welding.
To ensure reliability and safety, steel pipes undergo rigorous testing procedures such as water pressure tests, bending tests, flattening tests, and others, while adhering to specific surface quality standards. The standard delivery length typically ranges from 4 to 10 meters, with customers often preferring fixed lengths (or double lengths) for their convenience. As a dedicated supplier, we strive to meet these requirements and exceed your expectations with our high-quality Pengfa API 5L Seamless Pipes.
The API 5L Seamless Pipe specifications are designated by the nominal diameter, expressed in millimeters or inches, which differs from the actual physical diameter. The welded pipe category encompasses two main types: ordinary steel pipe and thickened steel pipe, distinguished by their specified wall thickness. The submerged arc welding (SAW) process employed in the production of straight seam steel pipe utilizes filler material and a granular flux to submerge the arc during welding, enabling the manufacture of pipes with diameters up to 1500mm. LSAW, an acronym for Longitudinal Submerged Arc Welded pipe, represents this technology.
The production of LSAW pipes involves advanced techniques such as JCOE forming and roll-forming submerged arc welding, offering versatility in manufacturing. For pipes with larger diameters, a dual-plate rolling method may be employed, resulting in a double-weld configuration. Compliance with various standards is ensured, including GB/T3091-2008 for low-pressure fluid steel pipes, GB/T9711.1-2-1997 for oil and gas steel pipes, and the internationally recognized API 5L standard for seamless pipes.
The range of production materials encompasses grades from Q195A to Q345E, 245R, Q345QA-D, L245 to L485, and X42 to X70. Pressure parameters are primarily defined by the ratio of 2ST/T, where S represents the yield strength and T is the wall thickness. Moreover, advancements in submerged arc welding have led to the development of two-wire and multi-wire welding methods, significantly enhancing production efficiency.
As a forefront supplier, we specialize in providing these seamless pipes that are meticulously produced to strictly adhere to the rigorous specifications outlined in the API 5L international standard. This meticulous compliance guarantees that our pipes exhibit unparalleled durability, unparalleled strength, and a consistent level of performance across a broad spectrum of applications, ranging from high-pressure oil and gas transportation to the conveyance of potable water.
Each and every inch of Pengfa API 5L Seamless Pipe embodies our unwavering commitment to perfection. These pipes are manufactured with impeccable precision, utilizing advanced technologies and techniques to ensure precise dimensional accuracy and superior surface finish. Their design is optimized to endure the harshest operating conditions, withstanding extreme temperatures, pressures, and corrosive environments with ease.
