Problems solved by technology
[0005] At present, the existing pipeline production enterprises basically use charcoal fire, boilers or workers to hold flame guns for heating. The temperature is uneven and the local temperature difference is too large, which is not conducive to forming. It not only wastes manpower, material and financial resources, but also has low production efficiency. , the quality is difficult to guarantee, let alone meet the high standard needs of customers
Moreover, the gas collecting pipe is an indispensable equipment in the gathering, transportation and distribution of natural gas. It has the characteristics of high pressure and large quantity. difficulty
