Focusing on the process of the major industrial countries of the world's welded steel pipe consumption and development , they have experienced a variety of structural adjustment process. When the technology level of welded steel pipe production increase, the cost will decrease, and the industry will develop.
To set up a design dimension standard of welded steel pipe provides basis of choosing material for manufacturing welded steel pipe and other pipes. Take the welded steel pipe widely used in the in physical and chemical industry as an example, to produce a welded steel pipe, company should chose the right diameter for the needs of flow velocity and flow rate, and the design dimension standard of welded steel pipe allows the diameter to fits the certain area using the certain kind of welded steel pipe.
This kind of design dimension standard of welded steel pipe is also an important basis for companies to choose the methods and equipment for confirming the scale of welded steel pipe production. No matter what kind of steel pipe a company want to produce, the welded steel pipe or the seamless steel pipe, there are big differences between design, production, circulation domain and so on. So that it is important to set up a design dimension standard of welded steel pipe to ensure the welded steel pipe produced is qualified and safe. What's more, the design dimension standard of welded steel pipe is also a basis for the standard of pipeline or elbow. The design dimension standard of welded steel pipe is a basic standard like the thread standard. To consider from the development level of a country's industry, the standard of welded steel pipe is deeply related to other industries, such as the oil and gas pipes, heat and nuclear pipes, that's the reason we urgently need the dimension stand.
The overseas design dimension standard of welded steel pipe are usually composed of piping, machinery and building industry in association with engineers, welded steel pipe, seamless steel tube panel and pipe fittings manufacturers. They are jointly formulated or approved by professionals from these areas. In order to establish the design dimension standard of welded steel pipe in line with international standards as soon as possible, the relevant departments of the welded steel pipe industry should not only the focus on connotation and further changes of the US and Europe standard, but also should remove the institutional barriers formed by history and continue to emancipate the mind.
