Abstract
The present invention provides a kind of melting connection technique of PPR pipe, the technique replaces the tubing of routine and the socket hot-melting mode of accessory by PPR pipe and the heat-melting butt-joint mode of tubing, solves PP R tubing in current industry and drainage after welding occurs with the big specification Chan Pin≤dn90 specifications of pipe fitting hot-melt adhesive paste.
Description
Technical field
The present invention relates to tubular object extruding technology field, more particularly, to a kind of melting connection work of PPR pipe
Skill.
Background technology
PP-R (atactic copolymerized polypropene) pipes have environmentally friendly, corrosion-resistant, service life long, with good heat sealability
Can, it is easy for installation, there is good term creep resistance energy and load performance, in house ornamentation hot water pipe under the conditions of applied at elevated temperature
It is able to quickly develop in market, is widely used in domestic water in industry and civil construction.
Because the PP-R pipe and pipe fitting of current industry production generally use hot-melt adhesive paste mode, once tubing or accessory
It can cause occur dry joint phenomenon, i.e. tubing between tubing and accessory on the premise of surface heating is (as shown in Figure 1) uneven or inadequate
The bad drainage for causing to have minim gap of welding between accessory surface.Because existing welder power is small, hot-melt welds
Area is big, once heating is uneven to will result in tube surfaces overheat or not caused enough the sealing-off (false fusion) of temperature or welding not
It is good, cause the position because of the drainage of the bad generation of welding.
The content of the invention
The present invention provides a kind of melting connection technique of PPR pipe, and the PPR pipe that the technique is processed is without leakage
Water phenomenon.
In order to reach above-mentioned technique effect, technical scheme is as follows:
A kind of melting connection technique of PPR pipe, comprises the following steps:
S1:The docking end face for needing the two sections of PPR pipes docked is heated;
S2:The docking end face of the PPR pipe of two sections of meltings is set fully to dock and be kept for some minutes, until two sections of PPR
Tubing completes abundant docking.
Further, it is to the detailed process that the docking end face of two sections of PPR pipes is heated in the step S1:
Clamp firing equipment with two sections of PPR pipes to be heated, and keep the docking end faces of two sections of PPR pipes fully with
Firing equipment is contacted, and first allows the firing equipment PPR pipe to be heated to two sections to carry out starting melting again after the preheated one-section time adding
Hot two sections of PPR pipes to be heated.
Further, the firing equipment PPR pipe to be heated to two sections is preheated until pair of two sections of PPR pipes
Contact surface occurs just stopping preheating during crimping.
Preferably, the temperature that the firing equipment PPR pipe to be heated to two sections is heated is 300 DEG C -500 DEG C.
Preferably, the retention time that the docking end face of the PPR pipe of two sections of meltings is fully docked is 5-30min.
Further, two sections of PPR pipes to be heated are fixed on hydraulic test, make two sections using hydraulic test
PPR pipe to be heated keeps sufficiently contact to reach the effect fully docked after melting.
Preferably, specification Shi≤dn90 of the PPR pipe.
Compared with prior art, the beneficial effect of technical solution of the present invention is:
Present invention process replaces the tubing of routine and the socket joint of accessory by PPR pipe and the heat-melting butt-joint mode of tubing
Hot melting way, solve PP-R pipe in current industry occur with the big specification Chan Pin≤dn90 specifications of pipe fitting hot-melt adhesive paste it is molten
Connect rear drainage.
