Product processing
1. Raw Material Selection: Manufacturers select steel based on the final application.Common materials include carbon steel (economical), galvanized steel (corrosion-resistant), and stainless steel (high-pressure/hygienic environments).
2. Precision Cutting: Raw pipes are cut into specific lengths using automated CNC sawsor shear cutters. Uniformity at this stage is critical for proper threading in subsequentsteps.
3. Threading Process: This is the most critical step. Specialized threading machinescreate male threads on one or both ends.Thread Cutting: Machines use precision dies to remove material (selective chipremoval) and form sharp, tapered threads.Thread Rolling: In mass production, hydraulic rolling machines deform the metal tocreate threads without removing material, which preserves the metal's strength.
4. Surface Treatment: After threading, nipples may undergo finishing processes likegalvanizing (molten zinc bath), black coating, or pickling/passivation for stainlesssteel to enhance longevity.
5. Quality Control: Every batch is inspected using thread gauges to verify pitch, depth,and taper. Visual checks ensure the removal of burrs or residue. s sinico sarice +10
