Is the circuit connection of the 380V butt welding machine correct, how can it be determined? Recently, a customer inquired about our WP630A butt welding machine, where the heating plate temperature stops rising after reaching 180°C. What could be the reason? In such a situation, the first step is to...

Butt welding machines are suitable for most thermoplastic materials, which soften when heated and solidify when cooled. ...

The professional construction team will make use of steel flanges to assist.The steel flange plate is used as a tool to hold and align short pipes and pipe fitting during the hot melt butt welding process. Its function is to provide a stable and secure connection during hot fusion butt welding of pipes, ensuring they are properly aligned and he...

When using a generator, the power recommended by Welping is 2 times as that of the pipe fusion machine. The machine's power is displayed on the specification label on the top of hydraulic station.For example, if the hydraulic station power is 10KW, the heating tool power is 1.5KW,and the planing tool is 1KW, then you need 25KW power for generator at least

Before butt welding, the pipe ends must be rounded and aligned. A pipe roller support will give more help in alignment and reduce the drag pressure. When the mismatch of the pipe walls is still out of local regulation, please adjust the clamping jaws by tightening down the high side until the pipe ends are even.

The digital temperature control indicates the internal temperature of heater. Some heat is lost on the transfer of heat to heater surface. In this case, it is better to use a thermometer to check the surface temperature of the heater. Use this as a reference to monitor the heater temperature during the fusion process.

number that indicates the maximum pipe size it can fuse. For example, butt fusion machine WP630A could fuse maximum pipe 630mm O.D., and from the specification chart, you could always find the minimum size it can fuse. If you have specific requirements for your projects, please consult with Welping sales.

Replacing the blade not depends on a certain period. But you should replace it when two sides of the blade are blunt or chipped. The life of blade varies depending on the hours of operation, material being face, periodical maintenance, etc.

A minimum of (1) complete revolution on each pipe end must be removed in order to expose clean material suitable for butt fusion. Always face to the stops to insure a square face-off perpendicular to the pipe.

The molten joint must be held immobile under force until cooled adequately to develop strength. The proper cooling times for the joint are dependent on the material, pipe diameter and wall thickness and are established by the pipe manufacturer or by applicable company, local, state, or federal standards. Allowing proper times under force for cooling prior to removal from the clamps of the machine ...

There are a variety of accessory items available depending on the machine size and application. See the butt fusion machine's product page for more accessories.Some examples are:InsertsRequired to fuse different pipe sizes that a machine can accommodate.Hydraulic Power Unithydraulic power units designed to meet the maximum system pressure desired on your job site. It offers low power consumption,a...

SDR pipe : "Standard Dimensional Ratio"The SDR pipe is the "Standard Dimensional Ratio" and refers to the geometry of the pipe. SDR is defined as the ratio of the nominal outside diameter to the nominal wall thickness.SDR = dn/enWhere dn is the nominal outside diameter of the pipe and en is the nominal (minimum) wall thickness of the pipe.Therefore a higher SDR indicates a thinner-walled pipe at a...
