Friend in welding industry to stay longer, must know water pipe, the heavy equipment welding technology is advanced, and the bending strength of drill pipe is very high, and welding more solid. But there are still a lot of friends in this kind of equipment don't know, also don't know how to use it, thus cannot give full play to its function.  First, ground water pipe production efficiency is very high, and the quality is very stable, many people know that the deep hole drilling is very high to the requirement of straightness, if we are not good for the product, it is easy to a problem. We need to explore water pipe discharge is very fast, so that hole forming effect is better.  Second, a lot of people like to use ground water pipe, because the ground water drill pipe sticking, it is not easy to have a lot of environment of slag discharge effect are not very good, then we can use ground water pipe. Ground water pipe is much higher than our artificial effect, and the work of high precision, many cases of human labor is more dangerous, but the use of ground water pipe is very safe.  Third, although the water pipe is very good, USES a lot in life, but we also want to choose a regular ground water pipe sales company. Such products will be more reliable, we will be more at ease to use. Many of the company's technology is not very good, and there is no after-sales service, so that there is something wrong with our equipment is unable to solve.  Fourth, have after-sales service work, find out problems, such can timely solve, for we will not delay the time of our work. But we also want to compare the sales the company's product price, if the price is too high, we will consider other home prices.
