Hebei Longrun Pipeline Group Company is a barred butt weld tee supplier in China providing pipeline fittings for industrial piping systems, oil and gas transportation, and energy infrastructure projects. Barred butt weld tees are commonly used in piggable pipelines where branch protection and flow continuity are important operational requirements.
A barred butt weld tee combines the structural design of a standard butt weld tee with internal reinforcing bars installed across the branch opening. During pigging operations, these bars prevent cleaning tools or inspection pigs from entering branch pipelines while allowing normal fluid movement through the system.
The butt weld connection design provides strong joint integrity and smooth internal flow transition, making barred butt weld tees suitable for high-pressure and large-diameter pipeline systems.
The factory supplies barred butt weld tees in a wide range of configurations, including:
Equal barred teesProducts are available in multiple diameter combinations and wall thickness schedules to match pipeline engineering requirements. Both standard and customized dimensions can be manufactured according to project drawings.
Common material grades include:
ASTM A234 WPB carbon steelMaterial traceability is maintained throughout production to ensure compliance with project specifications and inspection requirements.
The manufacturing process includes tee forming, branch preparation, internal bar installation, welding, heat treatment, machining, and inspection. Internal bars are positioned accurately to maintain pigging clearance while preventing obstruction of branch flow.
For welded barred tees, steel plates or pipes are fabricated using controlled welding procedures. Weld seams are inspected using nondestructive testing methods to verify integrity and structural reliability.
Heat treatment may be applied after welding to improve toughness and reduce internal stress, particularly for thicker wall fittings or alloy steel materials.
Barred butt weld tees can be supplied with different surface finishes depending on transportation and service conditions, including:
Shot blastingStandard bevel preparation is provided for field welding installation.
Quality control measures include:
Dimensional inspectionInspection documents and material certificates can be supplied according to customer requirements.
