The SUNTECHMACH SHG1600 is the largest machine in the SHG HDPE fitting fabrication machine range and covers 710mm to 1600mm for PE, PP and PVDF elbows, equal tees, equal crosses and 45°/60° Y-pieces. It is built around two numbers: an 84 KW total connected load and a 21,000 kg machine mass, and everything else follows from them. The heating plate is 72 KW and the hydraulic unit 8 KW, so both the plate and the clamp system are sized for the largest joint in the range; the working pressure class stays at 0-16 MPa. Practically, an SHG1600 is a project: the building, the supply, the foundation and the crane coverage are all decided before delivery, and the machine is commissioned as a cell rather than installed as a tool. Once running it delivers the same operating logic as the smaller models — a removable PTFE-coated plate controlled independently from 0 to 300°C with ±5°C surface deviation, a pivoting plate and planing tool with a safety limit switch, and a separate two-channel timer that counts soaking and cooling independently and alarms at the end of each.

Key Features

• 1. 710-1600mm Coverage — The widest range in the SHG series; extra-large fabricated fittings in one machine.
• 2. 72 KW Heating Plate — The largest plate in the range, sized so the face holds temperature across a 1600mm joint.
• 3. 8 KW Hydraulic Unit — Sized together with the plate for the heaviest clamp loads in the range.
• 4. 84 KW Total Load — Project-level electrical design: dedicated supply, switchgear and cable runs.
• 5. 21000 kg Project Cell — Building, foundation and crane coverage agreed before delivery; reinforced packing with steel base.
• 6. 0-16 MPa Pressure Class — Repeatable interfacial pressure on the thickest walls.
• 7. Pivoting Plate and Planer with Safety Limit Switch — Practical handling of the largest hot fitting.
• 8. Two-Channel Timer — Independent soaking and cooling counts with an end-of-phase alarm for cycle records.

Operation Guide

1. Commission the cell: verify foundation, supply rating and switchgear, hydraulic pressure hold, plate surface readings and crane coverage before any pipe is loaded.
2. Set up and square the clamps for the fitting type; close them dry and confirm the hydraulic circuit holds pressure without drift.
3. Load the pipe and fitting with the crane, bring the ends together and tighten the clamps; verify concentricity and axial alignment before planing.
4. Plane both faces until an even continuous chip forms on each side; confirm flatness and parallelism.
5. Set the plate temperature and let the face stabilise fully; re-verify the surface reading with the pipe in position.
6. Bring the ends onto the plate at the calculated pressure and hold for the soaking time on the 710-1600mm parameter table.
7. Pivot the plate out, join the ends within the change-over time and apply the fusion pressure.
8. Maintain pressure for the cooling time on the parameter table, re-checking clamp pressure at least once mid-cool; the timer alarms 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 710-1600mm range.

Q: Can it make Y fittings?

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

Q: What is the maximum pipe size on the 1600 model?

A: The welding range of the 1600 model is 710-1600mm, the largest in the SUNTECHMACH range. 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 1600mm machine need?

A: 380V, 50/60Hz, three-phase, 84kW total: 72kW heating plate, 4kW planing tool and 8kW hydraulic unit. A dedicated supply and switchgear are designed as part of the project.

Q: How much does the 1600mm machine weigh?

A: 21,000kg. Building, foundation, access route and crane coverage are agreed before dispatch, and the machine is commissioned as a fixed cell.

Q: Is a 1600mm machine delivered installed?

A: It is delivered as a project: layout, foundation, supply and lifting arrangements are settled in advance, and commissioning is carried out on site. Please contact us with your site plan before ordering.

Q: Does it record welding data?

A: Yes. The built-in printer records the welding parameters of each joint and the USB port allows export, which is how a 1600mm joint is 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. Actual 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 this size please also send the site plan, foundation details and available lifting capacity.

Q: Can the clamping configuration be customized?

A: Yes. Customized clamping solutions and OEM branding are available, built around the fittings and angles your project needs.

Q: Where is this machine manufactured?

A: In Hangzhou, China, by Hangzhou Suntech Machinery Co., Ltd. (SUNTECHMACH). The 1600 model is the largest machine in our HDPE fitting fabrication range.
