Longitudinal Pipe Weld

Before embarking on the utilization of Longitudinal Pipe Weld, meticulous construction preparation is paramount. This involves excavating the pipe trench and meticulously completing the pipe shaft masonry. To facilitate this process, essential equipment such as electric welding machines, cutting machines, electric hammers, and polishing machines must be arranged for the installation of straight-jointed steel pipes.

As a seasoned and proficient manufacturer, we are pleased to offer you Pengfa Longitudinal Pipe Weld, also known as Straight Steel Pipe in English. This versatile product, known as General Welded Pipe, is designed for transporting low-pressure fluids. It is crafted from high-quality steels like Q195, Q215A, Q235A, and Q235B plain carbon, and can even be produced alongside 0317 standard model 6012 and steel grade 755 mild steel, enhancing its weldability.

These steel pipes undergo rigorous testing, including water pressure, bending, flattening, and surface quality assessments, ensuring they meet stringent standards. Typically, they are supplied in lengths ranging from 4 to 10 meters, often in fixed lengths (or double lengths) to accommodate specific project requirements.

The specification of Longitudinal Pipe Weld is denoted by its nominal diameter, which differs from the actual diameter. Depending on the wall thickness, these pipes are classified into ordinary and thickened steel pipes. The welding process employs Submerged Arc Welding (SAW) technology for straight seam steel pipes, utilizing filler welding and particulate protective flux to achieve superior quality welds. With a production diameter capability reaching 1500mm, LSAW is the acronym for Submerged Arc Welding Straight Seam Steel Pipe. The production techniques encompass JCOE forming and rolling forming submerged arc welding methods.

In cases where larger diameters are required, two steel plates may be rolled together, potentially resulting in a double-weld phenomenon. Compliance with standards such as GB/T3091-2008 for low-pressure fluid steel pipes, GB/T9711.1-2-1997 for oil and gas steel pipes, and American Longitudinal Pipe Weld execution standards ensures international acceptance.

The production materials encompass a wide range, including Q195A-Q345E, 245R, Q345QA-D, L245-L485, and X42-X70. Pressure parameters are defined by 2ST/T, where S represents the yield strength and T signifies the wall thickness. Furthermore, Submerged Arc Welding has evolved into two-wire and multi-wire systems, significantly enhancing production efficiency.

As a frontrunner in the industry, the manufacturer employs cutting-edge manufacturing technologies and adheres to meticulous quality assurance procedures, ensuring that each and every weld on the Pengfa Longitudinal Pipe surpasses even the most stringent international quality benchmarks.

The emphasis placed on precision welding techniques is a hallmark of Pengfa's craftsmanship. By meticulously controlling the welding process, the manufacturer achieves seamless joints that exhibit unparalleled strength and durability. These joints, devoid of any imperfections, provide a robust and reliable connection, making the pipes suitable for the most demanding applications, from construction of towering skyscrapers to intricate infrastructure projects.

Moreover, Pengfa's reputation for innovation and customer satisfaction is well-earned. The company continually invests in research and development, pushing the boundaries of what's possible in the field of longitudinal pipe welding. This commitment to innovation, coupled with its dedication to delivering cost-effective solutions, has earned Pengfa a loyal following among contractors, engineers, and project developers across the globe. They recognize Pengfa Longitudinal Pipe Weld as the preferred choice for its exceptional quality, reliability, and overall value, making it a staple in their toolbox for tackling even the most challenging projects.
