The SUNTECHMACH SHG450 is the mid-size workhorse of the SHG HDPE fitting fabrication machine range: it fabricates PE, PP and PVDF fittings from 250mm to 450mm — 0-90° elbows, equal tees, equal crosses and 45°/60° Y-pieces — in a fixed workshop bay. Compared with the SHG315, the hydraulic unit is doubled to 3 KW while the heating plate rises to 8 KW, which is what lets it hold and align longer, heavier 250-450mm spools without the clamps creeping during the soaking phase; total connected load is 12.5 KW, still modest for a municipal or district fabrication shop. Working pressure stays at a low-starting 0-10 MPa with the same reliable sealing structure, the removable PTFE-coated heating plate is independently controlled from 0 to 300°C at ±5°C surface deviation, and the two-channel timer separates the soaking and cooling counts and alarms at the end of each. It remains a single-machine, multi-fitting tool: changing from an elbow to a tee means changing the special clamps, nothing else.

Key Features

• 1. 250-450mm Coverage — Matches the standard municipal distribution and branch sizes.
• 2. 3 KW Hydraulic Unit — Double the SHG315 clamp power, so long spools and heavy fittings hold alignment through the full cycle.
• 3. 12.5 KW Total Load — 8 KW plate + 1.5 KW planer + 3 KW hydraulic; practical on a normal 380V workshop supply.
• 4. Fixed-Bay at 2500 kg — Designed for a dedicated fabrication bay and forklift loading rather than site moves.
• 5. Multi-Angle Fabrication — 0-90° elbows, equal tees, equal crosses and 45°/60° Y-pieces; Y clamps and inserts are optional.
• 6. Low Starting Pressure at 0-10 MPa — Reliable sealing structure with an accumulator for pressure replenishment.
• 7. Removable PTFE-Coated Heating Plate — Imported Teflon coating, 0-300°C independent control, ±5°C deviation, pivoting for loading.
• 8. Separate Two-Channel Timer — Independent soaking and cooling counters with an end-of-phase alarm.

Operation Guide

• Install the tee/cross or elbow clamps for the fitting being made and check that the clamp faces are parallel.
• Load the pipe and fitting ends, bring them together with the handwheels and tighten the clamp bolts; verify concentricity before planing.
• Plane both faces until a continuous chip forms on each side.
• Set the heating plate temperature and allow it to stabilise.
• Bring the ends against the heating plate under the calculated pressure and hold for the soaking time on the parameter table.
• Remove the plate, join the ends within the change-over time and apply the fusion pressure.
• Hold the fusion pressure for the cooling time on the parameter table; the timer alarms when the phase ends.
• Release the pressure, open the clamps and inspect the bead on both sides for uniformity.

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 250-450mm range.

Q: Can it make Y fittings?

A: Yes. The machine is designed for fabrication of Y-type fittings with the corresponding clamping configuration; 45° and 60° Y fittings are supported.

Q: What is the maximum pipe size on the 450 model?

A: The welding range of the 450 model is 250-450mm. 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 450mm machine need?

A: 380V, 50/60Hz, three-phase, 12.5kW total connected load: 8kW heating plate, 1.5kW planing tool and 3kW hydraulic unit.

Q: Why does the 450 model have a bigger hydraulic unit than the 315 model?

A: Because 250-450mm spools are longer and heavier. Doubling the hydraulic power to 3kW is what keeps the clamps holding alignment through soaking and the long cooling phase, where a drifting clamp produces an oval or misaligned joint.

Q: How much does the 450mm machine weigh?

A: 2500kg. It is intended for a fixed bay with forklift loading rather than being moved between sites.

Q: What is the working pressure?

A: 0-10MPa with low starting pressure, a reliable sealing structure and a pressure accumulator for continuous replenishment.

Q: Does it record welding data?

A: Yes. The control panel includes a built-in printer for welding parameter records and a USB port for data export.

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.

Q: Can the clamping configuration be customized?

A: Yes. Customized clamping solutions and OEM branding are available. Tell us which fittings and angles you sell most and we build the clamping set around them.
