The SUNTECHMACH SHG630 is where the SHG range steps up to trunk-line work: it fabricates PE, PP, PVDF and PVDF-lined fittings from 355mm to 630mm — 0-90° elbows, equal tees, equal crosses and 45°/60° Y-pieces. Two things change at this size. The working pressure goes up from 0-10 MPa to 0-16 MPa, so the machine can develop the interfacial pressure needed once wall thickness and diameter both grow, and the heating plate jumps from 8 KW to 22 KW, which is what keeps the plate face recovery fast enough to hold a stable temperature across a 630mm joint instead of sagging when the cold pipe lands on it. Total connected load is 28 KW on 380V, so this model normally means planning the workshop supply and a fixed bay with lifting gear rather than moving the machine between jobs. The PTFE-coated plate, 0-300°C independent control, ±5°C surface deviation, safety limit switch on the planing tool and the separate two-channel timer are all carried over unchanged.

Key Features

• 1. 0-16 MPa Pressure Class — The first SHG model with the higher working-pressure range needed for thick-wall trunk fittings.
• 2. 22 KW Heating Plate — Fast face recovery so the plate temperature stays inside the ±5°C window during a 630mm joint.
• 3. 355-630mm Coverage — Covers trunk and sub-main sizes in one machine.
• 4. 28 KW on 380V — Plan the workshop supply and a fixed bay; the load is no longer a plug-in-and-go figure.
• 5. 3850 kg Fixed Installation — Sits on a dedicated bay with lifting gear for pipe and fitting handling.
• 6. Pivoting Plate and Planer — Solves the practical problem of loading a 630mm fitting into a hot machine.
• 7. Imported Teflon Coating, 0-300°C — Removable PTFE-coated plate with independent temperature control.
• 8. Two-Channel Timer — Separate soaking and cooling counts, with an alarm at the end of each phase.

Operation Guide

1. Set up the clamps for the fitting type and check the clamp faces are parallel and square to the frame.
2. Load the pipe and fitting with lifting gear, bring the ends together and tighten the clamps; verify concentricity before planing.
3. Plane both faces until a continuous chip forms on each side.
4. Set the heating plate temperature and wait for the face to stabilise — check the surface reading, not just the set point.
5. Bring the ends against the plate at the calculated pressure and hold for the soaking time on the parameter table.
6. Pivot the plate out, join the ends within the change-over time and apply the fusion pressure.
7. Hold the fusion pressure for the cooling time on the parameter table; the timer alarms at the end of the phase.
8. Release the pressure, open the clamps and lift the fitting out with the crane; inspect the bead all round.

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 355-630mm range.

Q: Can it make Y fittings?

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

Q: What is the maximum pipe size on the 630 model?

A: The welding range of the 630 model is 355-630mm. The maximum size that can actually be fabricated depends on the fitting type (elbow, tee, cross or Y) — contact us and we will confirm it for your specific fitting type and angle.

Q: What power supply does the 630mm machine need?

A: 380V, 50/60Hz, three-phase, 28kW total connected load: 22kW heating plate, 3kW planing tool and 3kW hydraulic unit. The supply should be planned before delivery.

Q: Why does the working pressure change to 0-16MPa at this size?

A: Because the interfacial pressure needed for a sound joint rises with both diameter and wall thickness. The 630 model is the first size in the range with the higher-pressure hydraulic class.

Q: How much does the 630mm machine weigh?

A: 3850kg. It is installed as a fixed bay and requires lifting gear for pipe and fitting handling.

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, so large-diameter joints can be documented for the project file.

Q: What welding temperature is used on a 630mm joint?

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: How many operators does it need?

A: We recommend two operators plus a small crane or jib for loading 355-630mm pipe and fittings.

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, including configurations for the specific fitting types and angles you produce.
