Welding equipment for polyethylene pipes

November 19, 2018

In our time, many ways to welding polyethylene pipes are known, but, as a rule, preference is given to welding over the heated tool, because it is this method that this method is considered ideal and most profitable. And in the case of the use of connecting parts, and with the direct connection of pipes with each other, this method is perfect.

The limit of strength and reliability in the use of the pipeline made of pipes fastened with welding are quite comparable to such indicators characteristic of a holistic pipe. Undoubtedly, the skill of the welder, combined with the working parameters of the welding and installation, is important in ensuring the quality of the welded joint.

This welding technique will keep such a property of polyethylene pipes as plasticity, and it will be characterized by a welded pipeline along its entire length. Regardless of which method of laying the mounted pipeline was provided for by the project (regular laying of pipes, laying the pipeline in an open method or testless renovation), it is possible to initially connect its fragments on the surface of the Earth, and after that, without any problems, it is already placed in intended for intended him trench.

The technique such as welding of polyethylene pipes in a heated tool is extremely convenient, for polyethylene pipes with a diameter of 63 mm or more, which has been used for quite some time. The ends of the connected pipes and (or) connecting parts are placed in the center of the unit for butt welding. Mechanical processing using the ending device is carried out only when the ends of the pipes are leveled, securely fixed and released from pinched pure h/b clinics. If in the process of processing the ends of the pipes a homogeneous shavings is formed with a thickness of about 0.5 mm, then you can extract the end device and inspect the mutual parallelism of the ends. If the gap between the connected surfaces is not more than the permissible value, then the ending has passed correctly, if this indicator is above the norm, the end should be carried out again.

The subsequent stage of welding of pipes and connecting parts is the heating of the ends using a special heating tool, on the surface of which an anti -stick coating is applied. After the melting and heating of the ends, the connected surfaces is diluted and the heating tool is removed from the welding zone. Further, the welded surfaces are closed and begins to press them to each other with a uniform increase in pressure to the optimal value. With the optimal value of the pressing pressure, the welded surfaces are withstanding for some time, during which the finished seam is cooling. The quality of the resulting connection can be judged by the educated seam, in height, width and appearance of the grata.

Volzhanin plant is an enterprise that has been specializing in the manufacture of various equipment for butt welding of polyethylene pipes of all kinds of types and sizes for a long time (63-1200 mm). In the ISO 9000 international system, the quality management of the specified plant dignifiedly withstand certification with the confirmation that it is absolutely complied with by all the standards of GOST R ISO 9001-2001 (ISO 9001: 2000) in the Euro-Register certification system.

The range of finished products and the services provided by Volzhanin LLC affects many areas of activity:

production of equipment for welding VSTOK Polyethylene pipes in the conditions of “field” installation of pipelines;

the manufacture of equipment for welding polyethylene pipes VSTOK used for the manufacture of connecting parts;

the manufacture of individual components and assemblies for use in the composition with other equipment for welding polyethylene pipes, namely: heating elements with automatic maintenance of the specified temperature, electromechanical and manual end devices, hydraulic stations;

the provision of repair services for domestic and imported welding equipment;

Providing services for the installation of polyethylene pipelines of varying degrees of complexity with leaving for the customer.
