Fusion of polyethylene pipes

preparatory stage

It is important to organize the previous welding operation, which will ensure easy and quick connections and their quality and reliability.They are similar for all types of welding and are as follows:

1. Site Preparation for work and welding equipment to process
2. surface of the pipe to be connect, cleaned and degreased, as well as connecting fittings
3. Held centering pipes and their connection
4. edges piping stripped and, if necessary, again degreased

Preparation of welding equipment must be carried out very carefully, taking into account the recommendations of the tool provider.In this case, the connection will be performed correctly and reliably, and the unit itself - have a long service life.It is important to regularly check on the performance of equipment and time to eliminate breakage.

unit for welding mounted on a flat surface where nothing will interfere with his work.Before you bring it into operation, you must do the following checks:

• Checking appearance of the device, the integrity of the insulating cover and ground
• energy generator is charged and conduct a trial inclusion
• check engine oil level in the hydraulic system
• device Verifyhow the mobile terminal and the sharpness of the blade cutter
• Reconciliation work instrumentation
• Special clips and inserts for pipe welding required diameter inspect and prepare the process
• details of applications which friction occurs, lubricated with special substances, according
• instructionsCleaning the heating element, cutter and other who need it the details of polyethylene trace and get rid the surface of fatty plaque

butt welding

welding technology plastic pipe butt involves heating of the edges of pipes and melting of the material under the influence of heatingwelder element, whereupon they are connected to form a monolithic fastening.

Instruction execution of works:

1. connecting part and butts piping melted to form a primary grata
2. Then the polyethylene heated to the temperature specified in the instructions - the material is softened, which provides the ability to mix on
3. molecular level heating element is removed andconnect the edges of pipes under pressure

last operation, called a technical pause, to be in time reduced to a minimum, as the need to avoid the cooling of the material and the loss of its plasticity, as well as not allow the particles to fall off dirt on the surface to be welded.

1. Butt welding forms a strong attachment, which is created on the basis of diffusion penetration of the material.
2. Weld cooled, giving it thereby the greatest strength of the finishing stage of the work

Electrofusion Welding

There is another technology of welding of polyethylene pipes - connection using electric fittings.As for the softening process the material using an electrical coil fitting.

Connecting pipes to each other by this method is as follows - in fittings installed metal wire, twisted spiral.Plastic melted using the device in certain parts to be welded - crossings, couplings, elbows, etc. Under the influence of the thermal energy released during the passage of current through the wire, the material is heated, forming a solid and reliable connection...

application of electric fittings is due to sum up the electrodes to the details of construction and implementation of the diffuse infiltration of the fitting and the pipe material and the molecular interaction.Formed high weld strength.

welding technology polyethylene pipes depends on the destination, the diameter and wall thickness and the type of pipeline.With proper organization and preparation of welding formed a high-quality connection of communications that subsequently will create an efficient and reliable system with a long service life.
