1.Raw Material Inspection & Blanking: Adopt high-purity copper tubes that comply with international pipe fitting standards. Strictly inspect copper material purity, wall thickness uniformity, surface finish, ductility and internal metallographic structure to exclude oxide layers, impurities and structural defects. Qualified copper raw materials are precisely cut into fixed-length blanks according to tee specifications, providing standardized raw materials for subsequent hot forging and forming procedures.
2.Hot Forging & Integral Forming:
Adopt professional high-temperature hot forging technology to complete integral three-way forming of copper blanks. Precise temperature control ensures uniform metal fluidity, complete tee branch molding and compact internal structure. The integral forging process avoids splicing gaps and welding seams, effectively improving overall structural tightness, pressure resistance and connection stability of the copper press tee.
3.Trimming, Shaping & Groove Machining:
Remove forging burrs, residual flashes and irregular edges on the tee surface and pipe orifices. Conduct fine shaping and calibration to ensure standard tee geometric size and smooth inner and outer wall finish.Precisely machine professional press-fit grooves at the pipe ends according to industry specifications, ensuring accurate groove depth, radian and position to achieve perfect matching with press tools and copper pipes.
4.Precision Polishing & Surface Treatment:
Implement multi-stage fine polishing treatment for both inner and outer walls to remove tiny scratches, oxide spots and machining traces. The smooth inner wall reduces fluid resistance and avoids medium residue and scale accumulation. Conduct professional surface cleaning, degreasing and anti-oxidation passivation to maintain the metallic luster and long-term corrosion resistance of copper materials.
5.Pressure Testing & Quality Inspection:
Carry out strict hydraulic pressure resistance test and air tightness leakage test to verify zero-leakage performance under rated working pressure. Conduct full-range quality inspection including dimensional tolerance detection, groove precision test, wall thickness uniformity check and surface defect screening. All products are strictly verified to ensure stable pressure resistance, reliable sealing performance and compliance with international pipeline engineering standards.
6.Marking, Packaging & Warehousing:
Mark qualified copper press down tees with specification, model standard, production batch and technical parameters. Complete sorting and counting, and adopt dust-proof, moisture-proof and collision-resistant professional packaging to protect precision groove structure and pipe surface. Finished products are classified and stored in warehouses and delivered after final inspection.
