Introduction
Certain projects demand non‑standard lateral tee dimensions—whether to fit tight spaces, match existing spool pieces, or accommodate unique flow requirements. Custom fabrication enables tailor‑made solutions.
1. Collaboration and Drawing Review
Engineering Consultations: Collaborate with process and piping engineers to define exact centerline offsets and branch angles.
CAD Modelling: Share 3D models to verify clearance and alignment before fabrication.
2. Material Procurement and Traceability
Special Alloys: Low‑temperature carbon steels, duplex stainless, or nickel alloys may be specified.
Heat Number Tracking: Ensure each custom tee’s material can be traced back to its original heat for quality audits.
3. Fabrication Techniques
Segmented Welding: Combine rolled run segments with machined branch inserts to achieve unique offsets.
Post‑Weld Heat Treatment (PWHT): Relieve residual stresses in alloy steels to prevent cracking.
4. Inspection and Acceptance
Custom Gauges: Manufacture inspection jigs to measure non‑standard offsets and verify branch angles.
Witness Testing: Offer third‑party oversight for critical projects in oil & gas or petrochemicals.
Conclusion
Custom lateral tees align pipeline design with real‑world constraints and performance goals. Hebei Longrun pipeline Group company specializes in custom fabrication, delivering detailed drawings, material certificates, and inspection reports to support project execution.
