Abstract
The present invention relates to a method for welding PE pipe, and is characterized by that a prefabricated PE material-made electrofusion component whose interior is equipped with electroheating wire is placed on the welding place of PE pipe, then two ends of the electroheating wire are connected with electrofusion welding machine so as to implement electrofusion welding operation. According to the different welding modes said electrofusion component can be made into the form of ring or band. Said invented method is low in cost, convenient for construction and can ensure welding quality.
Description
Technical field
The invention belongs to welding technology field, be specifically related to a kind of welding method of PE plastic tube.
Background technology
Along with the development of scientific and technological productive forces, the raising that the people require life, the performance of plastic product has obtained people's generally approval, and is applied widely.Plastic conduit strides into the municipal works field, and even enter into huge numbers of families, become an ordinary thing, the PE plastic tube is shown one's talent especially, more and more be subjected to people's favor with its good processing characteristics, serviceability and sanitation performance, its method of attachment also gets more and more people's extensive concerning as a ring important in the pipe technology.
At present, the method for attachment of PE pipe mainly contain that pipe fitting hot melt or electric smelting connection, butt fusion welding, outside hot melt belt connect, heat gun sweat soldering etc.When having relatively high expectations for large-diameter pipe (people can enter) and external diameter of pipe, these method costs are higher, the difficult control of external dimensions, and welding quality is difficult for guaranteeing.
Summary of the invention
The objective of the invention is to propose that a kind of cost is lower, easy construction and can avoid the welding method of human factor to the PE plastic tube of welding quality influence.
The welding method of the PE plastic tube that the present invention proposes is to place a PE material pad (being called the electric smelting sheet) that is provided with heating wire in prefabricated at the weld of PE pipe, then the heating wire two ends is connected electro-fusion welding and meets sb. at the airport, and carries out the electric smelting welding.
Actual needs according to the welding of PE pipe generally is divided into dual mode: end face welding between two pipes and the medial surface welding between the two ends, see Fig. 2 and shown in Figure 4.Corresponding thus, the electric smelting sheet can be made 2 kinds of different forms.
For the welding of two pipe end faces, the electric smelting sheet is done and is circularized, and its interior external diameter mates with the interior external diameter of pipe end, during welding the electric smelting sheet is placed between the ends of tubes, inserts electro-fusion welding and meets sb. at the airport, and extruding force is switched on a little, can finish the welding of pipeline.See shown in Figure 2.
The general width of above-mentioned annular electro fuse piece is narrower, and the distribution of heating wire can be the multi-turn multilayer, sees illustrated in figures 1 and 2.
For the medial surface between two ends welding, the electric smelting sheet is done and is become band, and during welding the electric smelting belt material is gone into interface tube place inwall, and with the support pressure device electric smelting band is fixed on the inside pipe wall, inserts electro-fusion welding and meets sb. at the airport, and switches on, and can finish the connection of pipeline.
Above-mentioned banded annular electro fuse piece, its thickness can be thinner, and heating wire distributes can be one deck multi-turn; The width of endless belt can broad, so that at the pipe medial surface solder side of broad is arranged, sees Fig. 3 and shown in Figure 4.
Pipe inner support pressure device provides fixing required holding power and the pressure of welding in the pipe, but manual adjustments shrink and swell, and have locking device, so that swelling and getting loose.
Among the present invention, pad (being the electric smelting sheet) is prefabricated, and its shape and size determine that according to the size of welding PE pipe draw at heating wire two ends wherein, so that be connected with electro-fusion welding machine.Electro-fusion welding is met sb. at the airport provides welding required voltage and current, adopts computer control, can import required numerical value, and exportable welding data, so that check and reference.
The inventive method, low cost, it is quick and convenient to construct, and general needs the several seconds can finish welding.And can guarantee welding quality.

Number in the figure: 1 is the electric smelting sheet, and 2 is heating wire, and 3 is the PE material, and 4 is connector lug, and 5 are the PE pipe, and 6 is electro-fusion welding machine, and 7 are the support pressure device.
The specific embodiment
Embodiment 1: be used for the welding that PE manages two pipe end faces, and weld external diameter φ 975mm, wall thickness is 25mm.
Electric smelting sheet 1 is a ring-type, external diameter Φ 975mm, and internal diameter Φ 925mm, promptly ring thickness is 25mm.The unitary resistance value of heating wire 2 is about 1 Ω/m, haves three layers every layer 4 circle in the PE material.The power of electro-fusion welding machine 6 is about 2000W～3000W.As shown in Figure 2, weld and get final product.
Electric smelting sheet 1 is banded, external diameter Φ 925mm, and the about 10mm of thickness, width are 40mm.The unitary resistance value of heating wire 2 is about 1 Ω/m, and one deck totally 5 circles are arranged in the PE material.The power of electro-fusion welding machine 6 is about 2000W～3000W, and welding support pressure device can swell to Φ 925mm in the pipe, and electric smelting band 1 is fixed in the inside pipe wall weld.As shown in Figure 2, weld and get final product.
Claims (3)
