Industrial Pipe Fittings Manufacturers

Industrial Pipe Fittings Manufacturers

Introduction
Industrial pipe fittings form the backbone of robust piping systems across a wide array of sectors, including oil and gas, chemical processing, power generation, and water treatment. As critical components that connect, redirect, and regulate the flow of fluids and gases, fittings such as elbows, tees, reducers, and flanges must meet stringent performance and safety requirements. Hebei Longrun Pipeline Group Company specializes in the manufacture and sale of high-quality industrial pipe fittings, supporting projects that demand reliability, precision, and compliance with international standards.

Comprehensive Product Range
Hebei Longrun Pipeline Group Company’s manufacturing portfolio encompasses:

Elbows (45° and 90°): Available in long- and short-radius variants to suit space constraints and hydraulic requirements.

Tees: Both equal and reducing configurations enable branching of pipelines without additional adapters.

Reducers: Concentric and eccentric types facilitate smooth transitions between different pipe diameters.

Caps and Plugs: Seal open ends of pipes for testing, maintenance, or temporary shutdowns.

Flanges: Raised-face, slip-on, and weld-neck flanges allow for gasketed connections in high-pressure applications.

Crosses and Stub Ends: Provide multi-branch connections and support lap-joint flange systems.

Each fitting is produced in carbon steel, stainless steel, alloy steel, and other materials based on project specifications. Custom orders—including special dimensions, wall thicknesses, and material grades—are fulfilled through Hebei Longrun’s flexible manufacturing workflows.

Manufacturing Excellence

Raw Material Selection

Procured billets and plates comply with ASTM, ASME, and GB technical specifications.

Mill test certificates ensure traceability of chemical composition and mechanical properties.

Forming Processes

Mandrel Bending and Hot Induction Bending for seamless continuity and uniform wall thickness in curved fittings.

Welded Construction for larger diameters and special angles, using automated submerged-arc welding.

Heat Treatment

Normalizing and quenching & tempering refine microstructure, improve toughness, and relieve residual stresses.

Machining and Finishing

CNC machining ensures precise dimensions for connection faces, bevels, and sealing surfaces.

Surface treatments—such as shot blasting, pickling, and passivation—remove scale and enhance corrosion resistance.

Quality Assurance and Testing

Hebei Longrun implements a multi-tiered inspection program:

Dimensional Inspection using calibrated gauges to verify center-to-face lengths, wall thicknesses, and curvature radii.

Non-Destructive Testing (NDT)

Ultrasonic testing (UT) for internal flaws in seamless components.

Radiographic testing (RT) for critical weld joints in fabricated fittings.

Magnetic particle testing (MPT) for surface defect detection.

Hydrostatic and Pneumatic Testing replicate operating pressures to confirm leak-tightness.

Mechanical Testing validates tensile strength, yield strength, and elongation according to project requirements.

A documented quality management system ensures batch traceability and full conformity with ISO 9001 procedures.

Applications Across Industries

Oil & Gas: High-pressure fittings for upstream extraction and downstream refining pipelines.

Petrochemicals: Corrosion-resistant stainless steel fittings in aggressive process streams.

Power Plants: Thermal and nuclear installations using alloy steels for elevated temperatures.

Water Treatment: Carbon steel and plastic-lined fittings for potable water and wastewater systems.

Mining and Minerals: Abrasion-resistant materials for slurry transport.
