Pipe Flange 500

Product Introduction

The pipe flange automatic welding machine PF500 is designed for welding pipes to pipes, pipes to flanges, and pipes to elbows for pipes under 600mm. It features a one-piece positioner with a 200mm through hole that can hold pipes with a diameter of up to 600mm. The positioner is equipped with a servo motor for rotation, stepper motors for vertical and horizontal movements, and a DC motor for wire feeding to achieve high automation. It is fitted with a water-cooled straight-handle welding torch and a three-dimensional wire feeding bracket, performing welding in a pendulum manner. The operation is simple, reproducible, and highly efficient.

Product Advantage

1. The pipe flange circular seam welding machine uses a fixed welding gun, and the positioner clamps the workpiece to rotate for welding.

2. The orbital TIG pipe flange welding machine uses Siemens PLC, Panasonic servo motor, and Weintek display screen to achieve intelligent touch control.

3. The automatic pipe girth welding machine for flanges has welding torches at different angles to meet various welding requirements.

4. The high precision pipe flange seam welding machine is highly automated; once the program and welding relative positions are set, welding can be completed with one button.

5. With an integrated design and high rotation accuracy of the positioner, the automatic pipe flange straight seam welding machine features pendulum welding with tracking function, resulting in higher welding quality.

Technical Parameters

Product Uses

1. Prefabricated Pipe Fittings Factory: Centralized mass production of straight pipe ends with slip-on/weld neck flanges, standardized welding of carbon steel and stainless steel pipe flanges, four-torch simultaneous inner and outer corner seam one-time forming, replacing manual batch prefabrication of pipe sections.

2. Pressure Vessel and Heat Exchanger Supporting Workshop: Welding of shell nozzle flanges and tube bundle flanges, prefabrication of pressure-bearing pipelines, welds requiring UT/RT non-destructive testing, compatible with full-position multi-layer multi-pass welding of weld neck flanges.

3. On-Site Mobile Construction: Installation of site pipelines, factory area technical renovations, pipeline modifications, and on-site piping work at oil and gas stations; portable rail/movable pipe flange machines; automatic welding of flange circumferential seams for overhead and buried pipelines on-site, suitable for complex field conditions.

Product Operate Guide

1. Preparation of the groove: Clean the pipe and flange grooves, remove oil, rust, and burrs, ensure the groove angle and gap meet standards.

2. Fix the pipe fittings in the machine chuck, position the flange against the locating fixture, align coaxially, control concentricity error ≤ 0.5mm, and tighten the fixture.

3. Parameter setting: According to the material (carbon steel/stainless steel/alloy steel), wall thickness, and groove, set the welding current, voltage, travel speed, gas flow, and multilayer welding paths.

4. Position the fixture and welding torch: Move the welding torch to the arc start point, adjust the torch distance and swing, and preflow argon/mixed gas.

5. Jog the equipment empty rotation to check that the pipe rotates smoothly and the welding torch does not collide.

6. Turn on protective gas, strike the arc, run a short test segment, and fine-tune the parameters.

7. Root welding: Argon arc root welding on one side with double-sided forming, ensuring full penetration at the root without slag inclusions or lack of fusion.

8. Fill welding: Fill the groove layer by layer, control temperature for each layer, and fill up to 80% of the groove volume.

9. Cover welding: Slight swing of the welding torch, the weld bead is uniform in width, and the reinforcement height meets specifications.
