6 Inch Hydraulic Automatic Tee Forming Machine

The 6-inch hydraulic automatic tee forming machine is a heavy-duty production unit designed for hot forming of equal and reducing tees from seamless pipe. It combines a 500-ton main cylinder, a 400-ton side cylinder, a two-stage hydraulic pump station and PLC control to deliver consistent, one-key tee forming for carbon steel and stainless steel pipelines.

• Design and manufacturing of the tee forming machine.
• On-site installation.
• Equipment debugging and commissioning.

• Maximum push-tube diameter: 168 mm.
• Minimum push-tube diameter: 60 mm.
• Wall thickness range: 4–8 mm.
• Push tee material: carbon steel seamless pipe (20G, A106B, A106C) and stainless steel pipe.
• Ambient temperature: 5–38 °C; relative humidity ≤ 82%.
• Input voltage: three-phase four-wire 380 V (−12% to +15%); frequency: 50 Hz ± 2%.
• Continuous 24-hour daily operation capability.
• Operating environment: non-corrosive air, indoor factory building with sufficient space.

• Manufactured in accordance with JB/T10205-2000 and JB/T15622-2005 standards.
• Cylinder body in 45# steel with inner surface finish Ra0.4.
• Piston rod in 45# seamless tube, chrome plated and polished after plating; free of straight lines and spiral lines, finish Ra0.2–Ra0.4.
• Remaining cylinder parts made of 45# forgings to ensure mechanical properties.
• Main cylinder piston guide sleeve uses a copper sleeve; all seals adopt the standard priority series; main oil seal imported from Austria AGco.
• Before assembly, cylinder bore, piston rod finish, hardness, matching dimensions, forgings and seals are inspected; every cylinder is pressure tested after assembly.

• Body fabricated from Q235A plate, welded assembly.
• Welds executed with high-quality 16Mo wire to ensure structural strength.
• Plates cut by full CNC flame cutting for dimensional accuracy.
• Panel thickness 50 mm; rib thickness 40 mm.
• Machine weight: 15 tons (theoretical weight).

• Maximum working pressure of the hydraulic system: 25 MPa; test pressure: 31.5 MPa.
• Anti-rust treatment applied to the inner and outer surfaces of the oil tank; filter screen installed inside the tank with liquid level and oil temperature display.
• The complete hydraulic system is cleaned before oil injection and test run.
• Two-stage pump station design: primary flow 80 L/min (high-pressure plunger pump); secondary flow 80 L/min (vane pump); motor 30 kW-6 with the vane pump mounted at the motor tail — one motor driving two oil pumps for effective energy savings.
• Jacking cylinder: 4 kW-4 motor with 10 L/min high-pressure plunger pump.
• Integrated connection design for stable operation and leak-free performance.

• Hydraulic propulsion with stepless speed regulation.
• PLC control with one-key forming; manual conversion available in the event of PLC failure.
• PLC display of speed, distance, hourly output and hydraulic circuit self-diagnosis.
• Feed time settable via touch screen with automatic stop.
• Hydraulic system pressure is settable, effectively protecting the equipment from damage caused by incorrect operation.
• All motor operation controls are centralized in a single operating cabinet.

• The supplier guides installation; the buyer actively cooperates.
• The supplier provides the equipment foundation drawing; the buyer constructs according to the drawing, with the supplier responsible for guiding construction.
• The supplier provides the medium-frequency cooling water supply and discharge plan; construction is carried out by the buyer.
• The buyer is responsible for routing the power cable to the position specified by the supplier.

• Once the buyer has met the commissioning conditions, the supplier completes equipment commissioning with the buyer's cooperation.
• The buyer provides debugging materials, 46# hydraulic oil and power supply.
• Equipment failures occurring during debugging are resolved by the supplier.

• The buyer carries out acceptance inspection in accordance with the technical agreement within 5 working days after commissioning is completed and the machine runs normally.
• After acceptance, both parties sign the acceptance slip for confirmation.
• From the date of acceptance signature, the supplier is responsible for maintenance and provides free spare parts for one year (excluding operational errors).

• Foundation diagram, hydraulic schematic diagram, circuit schematic diagram and layout diagram.
• One copy of the equipment instruction manual.
