Description:

Production Process:

• Material Selection: We primarily source raw materials from leading steel mills such as Baosteel, TPCO, Yanbao, Baotou Steel, Changbao, and Huarun. We select tubes with smooth internal/external surfaces, uniform wall thickness, and a preference for higher manganese content to ensure a superior final appearance.

• Material Inspection: Incoming materials undergo dimensional checks and chemical composition analysis.

• Warehousing: Approved materials are stored in inventory.

• Cutting: Tubes are cut to length with sufficient machining allowance. Burrs and metal chips are removed.

• Bending & Forming: Tubes are heated using medium-frequency induction heaters and formed via pushing with precision dies. Dies are re-polished every 48 hours of operation to maintain strict dimensional tolerances.

• Heat Treatment: Stress relief annealing (tempering) is performed.

• End Machining: Bevels are cut on 90-degree CNC lathes to an angle of 37.5° ± 0.25°. The land (flat edge at the end of the bevel) is sized according to the pipe diameter. The land ensures a flush fit for butt welding and prevents burn-through during the TIG root pass.

• Visual Inspection: Surfaces are checked for defects like scratches, peeling, or pitting.

• Chemical Analysis: Composition is verified using imported handheld spectrometers.

• Dimensional Inspection: Checks include outside diameter, wall thickness, ovality, and straightness.

• Mechanical Testing: Tests include flattening and flaring to validate performance.

• Sandblasting: A fine grit is used to create a uniform surface finish without excessive pitting.

• Painting: Surfaces are evenly coated using environmentally friendly spray equipment.

• Marking: Legible black background with white lettering is applied using a marking machine.

• Packaging: Products are packed in wooden cases or on pallets, secured with steel strapping, and wrapped in plastic film for weather and dust protection.

• Shipping: Careful handling using forklifts and overhead cranes ensures secure and orderly loading for transport.
