The SUNTECHMACH SHG1200 fabricates 710-1200mm PE, PP and PVDF elbows, equal tees, equal crosses and 45°/60° Y-pieces, and it is the model where the hydraulic system rather than the heating plate becomes the defining figure. The hydraulic unit rises to 7.5 KW, more than double the SHG800's 3 KW, because at this diameter the clamps have to hold and repeatedly correct a very heavy fitting through a long soak and an even longer cool — a weak or drifting clamp shows up directly as an oval or misaligned joint that cannot be re-worked. The heating plate is 62 KW and the total connected load is 73.5 KW, so this model is planned as a fixed cell with its own supply, a poured or steel foundation, and crane coverage. Working pressure remains in the 0-16 MPa class. The 0-300°C independent plate control, ±5°C surface deviation, pivoting plate and planer and the two-channel timer are unchanged from the rest of the range.

Key Features

• 1. 7.5 KW Hydraulic Unit — More than double SHG800's 3 KW; the clamp holds and corrects a heavy fitting through the whole cycle.
• 2. 710-1200mm Coverage — Trunk-line and transmission fittings in one machine.
• 3. 62 KW Heating Plate — Sized for the joint area at 1200mm so the face stays inside the ±5°C window.
• 4. 0-16 MPa Pressure Class — Repeatable interfacial pressure on very thick walls.
• 5. 73.5 KW Total Load — Planned fixed-cell installation with dedicated supply and switchgear.
• 6. 17000 kg Fixed Cell — Poured or steel foundation with full crane coverage for pipe and fitting handling.
• 7. Pivoting Plate and Planer — Practical loading of a very heavy hot fitting.
• 8. Two-Channel Timer — Independent soaking and cooling counts with an end-of-phase alarm.

Operation Guide

• Commission the cell first: confirm foundation level, switchgear rating, hydraulic circuit pressure hold and crane coverage before loading pipe.
• Set up and square the clamps for the fitting type; close the clamps dry and verify the hydraulic circuit holds without drift.
• Load the pipe and fitting with the crane, bring the ends together and tighten the clamps; verify concentricity and axial alignment before planing.
• Plane both faces until a continuous chip forms evenly on each side.
• Set the plate temperature and allow the face to stabilise fully, then re-verify the surface reading with the pipe in position.
• Bring the ends onto the plate at the calculated pressure and hold for the soaking time on the 710-1200mm parameter table.
• Pivot the plate out, join the ends within the change-over time and apply the fusion pressure.
• Maintain pressure for the cooling time on the parameter table, re-checking clamp pressure at the mid-point of the cool; alarm sounds at the end of the phase.

Common Faults & Solutions

FAQ

Q: Can this machine fabricate HDPE elbows?

A: Yes. The machine can be configured for fabrication of HDPE elbows at different angles. Please provide the required pipe diameter, SDR and fitting angle for machine selection.

Q: Can it produce HDPE tees?

A: Yes. With the corresponding clamps, the machine can be used for workshop fabrication of HDPE tees across the 710-1200mm range.

Q: Can it make Y fittings?

A: Yes. Both 45° and 60° Y fittings are supported with the correct clamping configuration.

Q: What is the maximum pipe size on the 1200 model?

A: The welding range of the 1200 model is 710-1200mm. The maximum size that can actually be fabricated depends on the fitting type — contact us and we will confirm it for your specific fitting type and angle.

Q: What power supply does the 1200mm machine need?

A: 380V, 50/60Hz, three-phase, 73.5kW total: 62kW heating plate, 4kW planing tool and 7.5kW hydraulic unit. A dedicated supply and switchgear should be designed before delivery.

Q: Why is the hydraulic unit so much larger on this model?

A: Because at 1200mm the clamps must hold and repeatedly correct a very heavy fitting through a long cooling phase. A drifting clamp produces an oval or misaligned joint that cannot be re-worked, so the hydraulic capacity is the critical specification.

Q: Does the clamp pressure stay constant during cooling?

A: The hydraulic circuit uses an accumulator for continuous replenishment, which maintains clamp pressure through the cooling phase rather than allowing it to relax.

Q: How much does the 1200mm machine weigh?

A: 17,000kg. It is installed as a fixed cell on a poured or steel foundation with crane coverage.

Q: Does it record welding data?

A: Yes. The control panel has a built-in printer for welding parameter records and a USB port for data export, which allows each 1200mm joint to be documented for the project file.

Q: What welding temperature is used?

A: The heating plate is adjustable from 0-300°C with ±5°C surface deviation. Heating and cooling times come from the welding parameter table supplied with the machine, based on diameter, SDR and wall thickness.

Q: What information is required to select a machine?

A: Pipe material (PE / PP / PVDF), pipe outside diameter, SDR or wall thickness, fitting type, required angle, power supply, and required production capacity. For a machine of this size, please also send the site plan and the lifting capacity available.

Q: Can the clamping configuration be customized?

A: Yes. Customized clamping solutions and OEM branding are available for the specific fitting types and angles you produce.
