The 9711 standard for longitudinal seam steel pipes includes GB T 97111-1997、gb/t 9711.2-1999、gb/t 9711.3-2005。GB T 9711 is a quality and technical standard for steel pipes in the oil and gas industry and is divided into three parts: A-grade steel, B-grade steel, and C-grade steel. The GB T 9711 standard has brought China's relevant standards into line with international standards, and has played a positive role in the production, operation and use of steel pipes in the oil and gas industry. The GB T 9711 standard is the higher standard in the current standard for longitudinal seam steel pipes. The testing methods mainly include: yield strength test, cold impact energy test, tensile test, chemical composition analysis test, flexural deformation test. 9711 longitudinal seam steel pipe is mainly used in the petrochemical industry. High-frequency welding and submerged arc welding technology are mostly used. The high-frequency resistance welding process mainly produces small- and medium-diameter thin-walled longitudinal welded pipes, and the double-sided submerged arc welding process only produces medium- and large-diameter thick-walled longitudinal welded pipes.
A better level is the convenience of the party has its own advantages, we all know that for users, when they apply a product, the first thing is to make it very convenient, because its own rest weight is relatively light, so when you apply a product, you can first make it rest weight to a very high level. And it itself has a great improvement in convenience, galvanized shed pipe is also mainly manifested in the installation, because it has a good design on the installation, so in the case of its own application, it can make itself very convenient, for users, there are also provisions in these aspects, and in the case of its own application, it can make it in its own service life, do a good main performance, for its own application of goods, for its own application of the galvanized shed pipe in its own service life, there are also high regulations. Because the L245M longitudinal seam steel pipe has been hot-dip galvanized, so in the case of its own application, it is mainly manifested in its long service life, if it is the application of ordinary metal hoses, it is easy to occur its own corrosion The main performance, if it is the user who applies such goods, it is not easy to occur its own rust The main performance, and the bento is because of its own hot-dip galvanizing treatment, so On the top of its own application, it can also improve its own beauty and generosity, and for such goods, its own beauty and generosity are also regulated.
