1：Basic Application Scope
Q1: What types of pipe materials can the machine process?
A: It is applicable to carbon steel, stainless steel, copper pipes, aluminum pipes, alloy steel pipes, galvanized pipes, seamless pipes and welded pipes. For high-hardness thick-walled pipes, heating shrinking dies can be equipped for processing.
Q2: What is the processing range of pipe outer diameter and wall thickness?
A: Standard models support pipe outer diameter from Φ4mm to Φ120mm with wall thickness ranging from 0.3mm to 8mm. Custom heavy-duty models can process thick-walled oilfield pipes with an outer diameter above Φ160mm.
2.Industry Application Scenarios
Q3: What components can be processed for the automotive industry?
A: It is widely used for processing automobile fuel pipes, brake steel pipes, seat frame pipes, bumper support pipes, exhaust pipe reducer joints, chassis shock absorption sleeves and air-conditioning copper pipe butt reducing ends.
Q4: What are the applications in furniture and hardware industry?
A: The machine is suitable for diameter reduction and end closing of iron and stainless，steel table & chair legs, guardrail pipes, clothes hanger round pipes, shelf connecting sleeves and sanitary ware pipe fittings.
Q5: Is it applicable for construction machinery and oilfield tubing?
A: Yes. It can process hydraulic oil pipe joints, hydraulic support guide pipes, oilfield tubing butt reducing ends, construction machinery pull rod reducers and conveying pipe connectors. It meets the pre-reduction processing requirements of API 5CT standard pipe fittings.
Q6: What are the applications in refrigeration, plumbing and pressure vessel industries?
A: It can process air-conditioning refrigerant pipes, water heater inlet and outlet pipes, radiator heat exchange pipes, end shrinking of small pressure vessels and floor heating pipe butt joints.
Q7: What pipe fittings can be processed for fitness equipment industry?
A: It is used for processing treadmill support pipes, dumbbell connecting rods, horizontal and parallel bar pipes, as well as diameter reduction and end closing of various fitness frame sleeve pipes.
3.Processing Technology Scope
Q8: What forming processes can the pipe shrinking machine complete?
A: The machine supports end shrinking, diameter reducing, pipe closing, heading, integrated expanding and shrinking, step diameter changing, pipe sealing, rib rolling shrinking and multi-pass progressive shrinking. It can precisely process pipe fittings to the assembly size for plug-in installation.
Q9: Will thin-walled pipes be flattened or wrinkled during processing?
A: The machine is equipped with standard inner mandrel fixtures to effectively prevent wrinkling and flattening of thin-walled pipes. Special customized dies are matched for soft metals such as copper and aluminum to ensure uniform and non-deformed pipe walls after processing.
4:Production Line Adaptability
Q10: Is the machine suitable for mass assembly line production or small-batch trial production?
A: Hydraulic models are designed for large-scale and continuous assembly line production. Small pneumatic models are perfect for sample processing and small-batch production. The machine can be combined with pipe cutting machines, pipe bending machines and automatic feeding racks to form an automatic integrated pipe processing production line.
Q11: Can it process pipe fittings for outdoor guardrails and steel structure engineering?
A: It is fully applicable. It can complete diameter reduction processing of fence round pipe plug connectors, scaffold sleeve pipes and steel structure support pipes, fully meeting the tolerance requirements of on-site welding and assembly.
5.Customized Application Scenarios
Q12: Can special-shaped pipe fittings be processed with customized dies?
A: Custom die service is available. The machine can process square pipe end shrinking, elliptical pipe reducing, eccentric diameter reduction, multi-step diameter changing and pre-shrinking of threaded pipes. Non-standard size processing can be realized by
developing new molds according to customer demands.
Q13: What pipes and materials are not applicable to this machine?
A: It cannot process large-diameter thick-walled seamless steel pipes (outer diameter over 160mm without customized equipment), brittle cast iron pipes, glass pipes and plastic pipes. Plastic pipe shrinking requires special thermal shrinking equipment, and this machine is only applicable to metal pipe processing
