Carbon emission amount in gas, protects environment, makes the brighter future in clear water blue sky.Dispersed supply of heating is all being phased out in each city
Mode, utilizing large power plant or heat supply factory to carry out central heating becomes a kind of development trend of current heat supply, central heating general
And degree is more and more higher.
Using central heating, the area of heat-supply service tenfold of each heat supply factory, Radix Achyranthis Bidentatae increase, and have used conventional heat-supplying mode
Through not reaching the temperature standard of national regulation, therefore when carrying out central heating, it is high that main pipeline more and more have employed high temperature
Pressure hot water heating, heat supply temperature reaches 130 DEG C, and pressure reaches 2.5Mpa.The diameter of pipeline has reached 1200,1400,1600
Mm, the length of main pipeline has also reached more than 10-30Km.
According to urban heating pipeline engineering construction and the requirement of acceptance specification (CJJ28-2014), heat supply pipeline should be by setting
Meter requirement carries out pressure test.During conventional pressure test, many employings are directly welded in pipe ends and are suppressed closure plate or suppress end socket
Mode.This mode is applicable to the pipeline of former medium-small diameter, after pipe diameter reaches more than 1200mm, as used weldering
Connect closure plate and welding end socket can cause situations below: one is that the thickness of closure plate and end socket is by a lot, than pipeline itself for increase
Wall thickness is big, and closure plate must the rigidity of ribbing reinforcement self could be used for suppressing, add the usage amount of material, simultaneously closure plate
Weight is the biggest, it is necessary to uses crane gear omnidistance cooperation in installation process, adds machine cost, along with the increase of thickness of slab,
Welding capacity also increases more, and pipeline welding one road junction such as 1400mm diameter needs specialty weld bond one time.After having tested, also
Needing end socket to excise, while the end socket of excision, also the main material of heat affected area is cut away, after cutting, the mouth of pipe also needs weight
New finished edge.Two be closure plate and end socket after multiple welding, cutting, the material of welding position changes the most greatly, exists the biggest
Hidden danger.Therefore closure plate and end socket can not be reused, and often must change with two to three times.So along with the change of pipe diameter is big,
The practice of conventional pipelines closure is the most less desirable at the cost of the aspects such as material, artificial, duration.
