怎么鑒別焊管材質(zhì)是什么？ |
怎么鑒別焊管材質(zhì)是什么？土方法有目測，火花鑒別，還可以使用儀器放在焊管上就能檢測出來，或者上質(zhì)監(jiān)局去檢測。
How to identify the material of welded pipe? The soil method is visual measurement, spark identification, can also be used in the instrument placed on the welded pipe can be detected, or the Quality Supervision Bureau to detect.
制造焊管的鋼材一般分為型材，板材，管材和金屬制品四大類，為了方便進行使用和區(qū)分，又可以分為終軌輕軌、大型型鋼、中型型鋼、小型型鋼、鋼材冷彎型鋼，優(yōu)質(zhì)型鋼、線材、中厚鋼板、薄壁焊管、電工用硅鋼片、帶鋼、無縫鋼管鋼材、焊接鋼管、金屬制品等品種。
Welded pipe steel is generally divided into profiles, plates, tubes and metal products, in order to facilitate the use and distinction, but also can be divided into light rail, large-scale section steel, medium-sized section steel, small-sized section steel, steel cold-formed section steel, high-quality section steel, wire, medium-thick steel plate, thin-walled welded pipe, electrical silicon steel sheet, strip steel. Seamless steel pipe, welded steel pipe, metal products and other varieties.
焊管可以通過不同的制造工藝進行區(qū)分，例如軋制方法，一般分為冷軋和熱軋，通過這兩種軋制方法生產(chǎn)出的產(chǎn)品叫做冷軋焊管和熱軋焊管，除此之外其制造工藝還有軋制，鍛造，拉拔，擠壓等工藝。
Welded pipes can be distinguished by different manufacturing processes, such as rolling methods, generally divided into cold rolling and hot rolling, the products produced by these two rolling methods are called cold-rolled welded pipes and hot-rolled welded pipes, in addition to the manufacturing process there are rolling, forging, drawing, extrusion and other processes.
除了上述的區(qū)分方法只在還有就是根據(jù)鋼材的含碳量進行區(qū)分，含碳量在0.04%-2.3%之間的叫做鐵碳合金，為了保證方管的塑性和強度一般含碳量不超過1.7%，1.5%為最佳含碳量，除此之外鋼材中也可以加入鐵，碳，硅，錳等元素。除了上面我們介紹的，還具有很多的區(qū)分方法，這里我們就不做詳細(xì)的介紹了。
In addition to the above distinction method is only based on the carbon content of steel to distinguish between 0.04% and 2.3% carbon content called FERROCARBON alloy, in order to ensure the plasticity and strength of square tube carbon content generally does not exceed 1.7%, 1.5% is the best carbon content, in addition to steel can also be added iron, carbon, silicon, manganese and other elements. In addition to what we've described above, there are many ways to distinguish between them, and we won't go into details here. 標(biāo)簽:
