Shandong Panjin Steel Pipe Manufacturing Co., Ltd. plans to build one seamless line pipe deep-processing line for pipes with diameter φ32–φ159 mm, wall thickness 3.5–25 mm, and length 6,000–13,000 mm, with a designed annual processing capacity of 75,000 tons of line pipes and other pipe products.
In accordance with the customer’s production requirements, our company conducted an on-site survey and held in-depth technical communications with the customer’s technical team. Following five face-to-face technical exchanges and obtaining full customer approval, our team carried out expedited design work. Within 10 days, both parties finalized and signed the technical specifications as follows:
Pipe Cutting Machine Type: Disc-type pipe cutting machine (equipped with chip removal and collection system)
Conveyor Roller Table Speed: 0.5–2 m/s (variable frequency adjustable), with individual drive for each roller. Motor power: 1.5 kW AC, adopting dedicated roller table motors.
Rollers are V-shaped; roller length: 200 mm; roller ring diameter: 240 mm; throat diameter: 150 mm; included angle: 125°. Basic center distance between conveyor rollers: 1,500 mm.
