Hebei Longrun Pipeline Group Company is engaged in selling industrial pipe fittings designed for use in a wide range of piping systems, including oil and gas transportation, chemical processing, power generation, water supply, and industrial infrastructure projects. Industrial pipe fittings are critical components that connect, direct, or terminate pipelines, ensuring safe and efficient fluid transmission under varying operating conditions.
Our product portfolio includes elbows, tees, reducers, caps, flanges, and other commonly used fittings. These products are available in carbon steel, low-alloy steel, and alloy steel grades, manufactured in accordance with international standards such as ASME, ASTM, API, and relevant EN or GB specifications. Both seamless and welded fittings can be supplied depending on size, pressure class, and application requirements.
Dimensional accuracy and compatibility with standard pipe schedules are key considerations in industrial applications. Our fittings are produced to match standard outer diameters and wall thicknesses, allowing smooth integration into existing pipeline systems. Special dimensions and non-standard configurations can also be arranged based on engineering drawings or project needs.
Industrial pipe fittings supplied by Hebei Longrun Pipeline Group Company are manufactured using controlled forming processes such as hot pressing, cold forming, extrusion, and welding. Raw materials are inspected for chemical composition and mechanical properties before production. Throughout manufacturing, dimensional checks and visual inspections are carried out to ensure consistency.
Quality control includes mechanical testing, such as tensile and impact tests, as well as nondestructive examinations like ultrasonic or magnetic particle testing. These inspections help verify internal soundness and surface quality, reducing risks during installation and operation. Each batch is delivered with complete documentation, including material test certificates and inspection reports.
To protect fittings during storage and transportation, surface treatments such as shot blasting, painting, or oil coating are applied as required. Beveled ends are prepared for butt-weld connections, while threaded or flanged ends are available for low- and medium-pressure systems. Clear marking on each fitting ensures traceability from raw material to final delivery.
With established logistics and export experience, Hebei Longrun Pipeline Group Company supports customers in different regions by providing stable supply, packaging suited for long-distance transport, and coordination with inspection agencies when required.
Industrial pipe fittings are widely used in pipelines carrying oil, gas, steam, water, and chemical fluids. Typical applications include refinery process lines, power plant piping, industrial boilers, municipal water networks, and manufacturing facilities. By focusing on standardized production and quality management, our fittings support long-term operation in diverse industrial environments.
