TPEP anticorrosive steel pipe range of use and laying
Water resources exist uneven distribution in the world scale, so the long distance water transmission line has been established in the world scale, and the phenomenon of northern water resource shortage exists in our country, so the famous south to north water diversion project has been developed
In addition, there are all kinds of water diversion projects: yellow to Jin, yellow to Qing, river to Huai and so on. At the same time, in recent years, the urban-rural water supply integration project that the state focuses on has been implemented all over the country, which puts forward high requirements for our long distance pipelines.
In the continuous practice and exploration, we found that TPEP anticorrosive steel pipe with incomparable advantages to all kinds of products, in the long distance water transmission line has been widely used.
Some advantages of TPEP anticorrosive steel pipe
TPEP anticorrosive steel pipe refers to the steel pipe that can reasonably prevent or alleviate the corrosion caused by chemical or electrode reactions during transportation and use after being cleaned by anticorrosive methods. It has the advantages of small pipe roughness, clean inner cavity and good hydraulic characteristics
Therefore, TPEP anticorrosive steel pipe can be used in mine water supply, underground shotcrete, positive differential pressure exhaust, process sewage waste and power plant backwater transmission pipeline. However, with so many advantages, TPEP anticorrosive steel pipe also needs to pay attention to some matters in daily use.
As the corrosion of ordinary steel pipes is severe under extreme conditions, the service life of steel pipes will be reduced. Therefore, anti-corrosion steel pipes should be produced in time. Since there are many manufacturers of anti-corrosion steel pipes, there are many specifications and specifications of TPEP anti-corrosion steel pipes in the market, so it is necessary to grasp the correct method in the transportation process to prevent the damage caused by unreasonable transportation
TPEP anticorrosive steel pipe laying method
Generally, TPEP anticorrosive steel pipe is laid under the dam, which consists of water inlet, pipe body and outlet section. The pipe body should be set on a good basis, rather than on the fill of the dam body.
The concrete or masonry cushion should be set between the pipe body and the foundation, the expansion joint should be set 11-22 meters apart along the pipeline, and the water stop valve should be set at the joint, so as to properly thicken the anti-leakage structure such as clay core wall or inclined wall
Backfill 1-2 meters of anti-seepage soil material outside the pipeline, and set an intercepting ring at an interval of 11-22 meters outside the pipeline to increase the diameter of water seepage on the surface of the pipeline to prevent water seepage.
Well, that's it for today! Hope you can understand, in order to play the necessary transport and corrosion protection, to ensure the smooth progress of the pipeline system.
