Apparatus for welding of polyethylene pipes : when and why you need

What polyethylene pipes or HDPE PE100

Before choosing on the market the professional equipment and machines for welding of polyethylene pipes, it makes sense to evaluate three important points:

• length of your network and the number of connecting nodes;
• real mode of using water (sewerage, heating) systems based on PE80 or HDPE pipes;
• acquisition costs of a simple apparatus for welding pipe sections given to the cost of one meter of the finished pipe.

At its core, this may be one and the same tubular.It is important to remember that different labeling and trade names not override the provisions of the interstate standard GOST 18599-2001 Polyethylene pipes, which you will mount via yet unknown apparatus of butt welding.Let's look at the assortment:

Category	Nominal diameter, mm	Max.pressure MPa
PE32	10 - 160	0,25 -1,0
63	16 - 1200	0,25 -1,0
	80 16 -1200	0,5 - 1,25
100	32 - 1000	1,0 - 1,6

comment operating parameters and operating condition of polyethylene tubes for different we will not engineering systems,these products for decades are excellent both in the centralized water supply systems, as well as at private suburban areas.

basic physical properties of plastic products:

• able to work in any communications with a constant water temperature up to 80 degrees;for suburban buildings such thermal stress not typical;
• oddly enough, but the material has a lower density than water, which flows in polyethylene pipes;specific weight per meter of standard pipe diameter 120 cm weighs about 207 kg;
• highest elasticity: tension, even when the weakest of hydraulic and mechanical loads by 10-20% will not sustain any metal pipe, and we have 60-80;
• low coefficient of internal friction;the roughness of the pipe rolled polyethylene should not exceed 0,005 mm.

agree that the correct choice of diameters, wall thicknesses and correct butt welding machine such certified plastic pipe assembly may be decades, even in the collective engineering networks.

equipment for welding of polyethylene pipes

Apparatus for welding of HDPE (term: Low-pressure polyethylene with molding) pipe connections for different purposes can be subdivided into three categories:

1. MMA joint manner of small diameter systems.Headache and a poor substitute for common fittings in a private building.Easier and cheaper every year to buy new couplings and union tees than seek leakage places in the winter of broken weld seams running water and run the machine for welding of polyethylene pipes throughout the site.
2. MIG welding of polyethylene pipes, as a rule, partially replaces the mechanical assembly for a perfect hydraulic device.Docking and scalding compounds takes place in the presence of the operator, but many of its functions are substantially alleviated.
3. Automatic welding equipment for PE pipes.It would be strange if such devices for industrial piping does not come up.Human function minimized automatic programmed on system parameters (material, diameter, and wall thickness of the tube even on the climatic conditions), itself determines the temperature and time of heating the joints.

Select the device for electrofusion

If you really decide on the wiring of a stationary pipe of polyethylene structures on the site and are ready to perform their welds with your hands, pay attention to the units of this type:

machine name	range of diameters to be welded, mm	power consumption, kW	Weight	Price, rubles.
MSA 250 PLUS	20-710	3,78	11,5	153,3
MSA 350 PLUS	20-710	3,78	11,5	257,9
Highway M	20-630	4,0	16,0	105,5

We dare to assure you that this is the most affordable prices on these devices so buythem, even a purse with its neighbors, it makes no sense.To carry out such work with the IPA should be professionals, and we, the poor cottagers will have to pay for depreciation of equipment.
