钢管在我们的日常生活中随处可见，它广泛应用在供暖、供水、油气及其它工业液体的输送等方面，为我们的生活和生产带来了极大的便利。
Steel pipes can be seen everywhere in our daily life. It is widely used in heating water supply oil and gas and other industrial liquid transportation which brings great convenience to our life and production.
工业上用钢板或钢带生产直缝钢管只有几种方法，其原则上的不同在于钢管的成形方法上，成形后钢管后续加工过程基本上是相同的。成形方法原则上取决于钢管焊缝的分布 按焊缝的分布将钢管分为两种基本形式：直缝钢管和螺旋缝管。与此相应，焊管生产分为直缝钢管的生产和螺旋缝管的生产。直缝钢管和螺旋缝管应用最广泛的焊接方法是埋弧焊（SAW），其质量好、生产率高、技术成熟、稳定。
There are only several methods for producing straight seam steel pipes with steel plates or steel strips in industry. The difference in principle lies in the forming methods of the steel pipes. The subsequent processing process of the steel pipes after forming is basically the same. In principle the forming method depends on the distribution of the welds of the steel pipes. According to the distribution of the welds the steel pipes are divided into two basic forms: straight seam steel pipes and spiral seam pipes. Correspondingly the production of welded pipes is divided into the production of straight seam steel pipes and the production of spiral seam pipes. The most widely used welding method for straight seam steel pipe and spiral seam pipe is submerged arc welding (SAW) which has good quality high productivity mature and stable technology.

The welding process of straight seam steel pipe is simple the welding cost is low and the production speed is fast. It is relatively common in the market and it is a widely used product. What are its application scopes?
目前，国内外直缝钢管广泛应用下述范围：
At present straight seam steel pipes at home and abroad are widely used in the following areas:
·陆地和海洋输送气、水和石油的干线管道；
Trunk pipelines transporting gas water and oil by land and sea;
·化学工业输送化工原料和产品用管；
Stainless steel pipes for transporting chemical raw materials and products in the chemical industry;
·海洋工业结构用管；
Pipes for marine industry structures;
·锅炉制造用管和特殊用途的结构管。
Tubes for boiler manufacturing and structural tubes for special purposes.
正由于直缝钢管与人类生活、生产活动密不可分，直缝钢管工业的生产技术不仅发展，而且推陈出新，直缝钢管生产在钢铁工业中占有的位置。
Just because the straight seam steel pipe is inseparable from human life and production activities the production technology of the straight seam steel pipe industry not only develops but also brings forth the new and the straight seam steel pipe production occupies a position in the iron and steel industry.
不管是什么行业，都要注重产品品质的发展，这样对于用户是一种负责的表现，这对今后企业的发展有着重要意义。
No matter what industry it is we must pay attention to the development of product quality which is a responsible performance for users which is of great significance to the development of enterprises in the future.
