With our brands, we are better at offering differentiated machines and tools to suit various requirement from market and better serve our customers.

"WELPING", covering all plastic related tools, for professionals.

"YOVIDA", stands for new tech adopted, high level tools.

"DOWELD", mainly focus on cost balancing items.

"DERUIBAO", mainly focus on domestic market.

WELPING model WP315A or WP315B are of standard welding size from 110mm to 315mm, and can be extended to 90mm.

Although the clamps (reducers) size 63mm and 75mm can be installed to WP315A or WP315B, but pipes below 90mm cannot be trimmed on the machine.

We have 2 recommendations:

1.If the welding job of size 63mm isn't frequent, we suggest to buy a standard hydraulic butt welding machine, model WP315A or WP315B (size: 110mm-315mm), and a manual butt welding machine, model WP160C or WP160D (size: 63mm-160mm). This combination can cover all the requirement and also cost-saving.

2.If the welding sizes involves many 63mm pipes, we suggest to buy a standard hydraulic butt fusion welding machine model WP315A or WP315B, and model WP160A or WP160B. Hydraulic butt welding is always the professional choice for decent jobs.

 

First, to check the pipe size need to be welded, for example from 110mm to 315mm.

Second, to check the actuation type, like hydrualic or manual. Manual butt welding machine only available up to 250mm

If you are not sure which model is most suitable, please always contact our sales representative to help.

 

 

In some applications, the HDPE pipeline is pressurized, which had high requirement of reliability. Butt welding joints provide very stable sealing performance, like a complete pipe.

 

Butt welding is a popular method of jointing the HDPE pipes. With proper operation, it can provide very reliable performance in any working condition. The product consists of pipe end trimming, heating up, melt jointing, which require reliable butt welding machine to get a good job done.

 

Operation：

1.Automatic machine features：

The automatic machine completes milling,heating, joining and other tasks by operation through the LCD screen. The operator only needs to confirm pipe sizes, material and SDR standard, other parameters are automatically set by the machine. The heating plate automatically jumps up after heating procedure, then the pipes will automatically join. Even inexperienced personnel can complete the welding operation according to the instructions on the LCD screen.

2.Simi-automatic machine features：

The operator needs to manually input the parameters of temperature, pressure, time etc according to operational manual. The heating plate needs to remove manual. Pipe jointing, pressure adjusting and holding need to set on hydraulic station manually.

3.Generally speaking, the automatic machine can achieve a smooth, accurate, no-manual interference operation experience, and the welding quality is strictly guaranteed. The semi-automatic machines require experienced operators to participate in the full operation. 

Product structure：

1.The structure of the hydraulic stations is different. The automatic machine equips chip-controlled electrical and hydraulic systems while the semi-automatic equips traditional electrical and hydraulic systems.

2.The automatic machine frame adopts heavy duty structure design with a heating plate auto-jumping device.

3.The automatic machines are equipped with precision-machined clamps (reducers) as standard, while semi-automatic machines are equipped with die-casting clamps .
