Pipe Making Machinery Production Process  Coil preparing  → Uncoiling  → Shear/end welding  → Strip delivering → Strips accumulator  → forming and sizing  → flying saw → output runway  → packaging  → storage   4. Pipe Making Machinery Main technical parameters •  Material: low carbon steel, low alloy steel, tensile strength σb≤450MPa, yield strength  σs≤350MPa •  Strip width: 60-200mm •  Strip thickness: 1.0-3.0mm •  Pipe spec. : round pipe: dia. 38-63mm; square pipe: 20X20-50X50mm; rectangular pipe: 25X50-40X60mm. •  Pipe length: 6m±3mm •  Coil spec : coil ID φ450-φ550mm; coil weight ≤2MT •  Heating mode: 250KW solid-state HF induction heating •  Forming speed: 70-90m/min •  Electrical installed capacity: Approx. 500KW •  Compressed air: 4-6 kg/cm² •  Cooling water flow: 20m3/h   5. Pipe Making Machinery Main machines     5.1Pipe Making Machinery Uncoiler Structure: The double work station decoiler, it is manual rotary type and double work station manual harmomegathus. It contains two main parts: main body and the fixed base. The main body is equipped with expanding and contracting system, braking of the mandrels, one cone is working and the other is preparing, then turn 180°to work.   Parameters:   Strip width: 60-200mm   Coil OD: Φ1500mm   Coil weight: 0.5-2.0MT   5.2Pipe Making Machinery Shear/end welder In the shear/end welder the ends of the coils are cropped, precisely aligned and welded together in the shortest possible time.  

Shear form:	Manual guillotine shear
Welding form:	Pneumatic material platform, Manual welding with CO2 gas shield welder

  5.3 Pipe Making Machinery Two rollers delivery machine It is mainly gantry type frame, the lower roller drive, equipped with guidance vertical rollers and horizontal material pressure rollers. It can deliver the after welded steel strips into the material collecting box, maintaining enough material in material accumulator.       5.4 Pipe Making Machinery Cage type accumulator   A continuous production process is ensured by accumulator, which bridges the standstill time in the strip preparation section during the welding of the coil ends. The structure is overall frame type, made of fixed frame, activity frame, and strip support rollers and tension rollers. It is adjustable freely based on the strips width.   Parameters:  

Allowed stripes width	60-200mm
Stripes thickness scope	1.0-3.0mm
The feeding speed	Max. 90m/min
The filling speed	Max. 160m/min
Stored length	600-800m

                            5.5 Pipe Making Machinery Forming and sizing machine   This machine adopts roller type forming principle and high-frequency induction welding. The strip is fed into the forming machine by the feeding device in the mill and the forming roller continuously rotate and press the strip into the required shape.       Structure: forming section, sizing section, guiding device, squeezing rollers, outer scraping, water cooling, and turkey heads.   Stands no.:   Feeding section: 1 level roll stand, 1 guiding side roll stand, 1 five-roll straighter.   Forming section: 7 level roller frames, 8 vertical roller frames;   Sizing section: 6 level roller frames, 5 vertical roller frames, 1Turk’s head     5.6Pipe Making Machinery Computer control flying saw   Computer control flying saw is used for cutting tubes to length in the line. It is mainly consists of lathe bed, gears, rack cabinets, saw car, clamps, speed measurement system, driving system, electrical system, carrier rollers and so on.       5.7 Pipe Making Machinery Pipe Output conveyor and packaging machine The pipe output conveyor consists of runway, reverser, and pipe bench. Runway: is used for conveying the finished pipe from flying saw to the packaging machine. Reverser: it is an auxiliary device, can achieve carrying the pipe from runway to the bench by its turnover mechanism. Pipe bench: A carrier for temporarily storing steel pipes on it in order to leave times for packaging pipes. Packaging machine: can be hydraulic or manual type.           6.Pipe Making Machinery CONTACT PERSON: MS. Olivia Chen whatsapp:008618630440999 Skype:olivia-chen-hebei QQ:2543208397
