Carbon Steel Butt Weld Tee Pipe Fitting Manufacturer & Supplier

As a China-based manufacturer and exporter of carbon steel butt weld pipe fittings, we produce ASME B16.9 butt weld equal tees for global industrial piping projects. This CF415K equal tee is a butt-weld branch fitting engineered for equal flow split and combination in process piping, widely adopted in oil & gas, chemical, thermal power, water treatment and cross-country pipeline systems.

This butt weld equal tee is manufactured by hot forming. The three branch ends share identical nominal diameter and wall thickness, designed to be joined with adjacent pipe via circumferential butt welding on site. The DN150 unit features 168.3 mm outer diameter and SCH40 wall thickness, fully complying with ASME B16.9 requirements for butt-welded fittings. CF415K carbon steel delivers reliable tensile performance, pressure bearing capacity and adequate notch toughness, resisting creep and crack initiation under sustained operating pressure and temperature, which meets the stringent safety criteria of process plant piping.

Our finished butt weld tees receive uniform black anti-rust paint coating. The smooth, pinhole-free paint layer isolates substrate from moisture and airborne corrosion during ocean freight, site storage and pre-installation standby. The coating exhibits good adhesion and scratch resistance, avoiding peeling before field erection. Alternate surface finishes including temporary rust preventive oil or bare metal are available upon project specification.

Each fitting carries indented steel marking mechanically stamped into the outer surface. The marking includes brand code, size, schedule, material grade and applicable standard. The stamping is recessed into steel matrix rather than printed or raised, compliant with ASME marking rules, legible after coating and enabling full material traceability for inspection and audit.

Quality assurance covers the entire production workflow. Raw pipe undergoes chemical and mechanical property verification before hot forming. After forming and trimming, every butt weld tee is subjected to dimensional check, wall thickness measurement and visual inspection. Hydrostatic test and NDT (non-destructive testing) such as UT or MT can be performed for critical service applications. We issue MTC (Material Test Certificate) traceable to raw material heats, and accept third-party witnessing or inspection by SGS, BV or client appointed surveyors. All export documentation including commercial invoice, packing list and certificate of origin can be prepared for customs clearance.

We serve EPC contractors, pipeline distributors and end-user plant owners worldwide. For shipment protection, tees are packed in fumigated wooden cases or export pallets to prevent impact damage during sea transit. As a direct factory supplier, we eliminate middleman markup and offer competitive pricing for project orders.
