怎么鉴别焊管材质是什么?


怎么鉴别焊管材质是什么?土方法有目测,火花鉴别,还可以使用仪器放在焊管上就能检测出来,或者上质监局去检测。
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.
制造焊管的钢材一般分为型材,板材,管材和金属制品四大类,为了方便进行使用和区分,又可以分为终轨轻轨、大型型钢、中型型钢、小型型钢、钢材冷弯型钢,优质型钢、线材、中厚钢板、薄壁焊管、电工用硅钢片、带钢、无缝钢管钢材、焊接钢管、金属制品等品种。
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.
焊管可以通过不同的制造工艺进行区分,例如轧制方法,一般分为冷轧和热轧,通过这两种轧制方法生产出的产品叫做冷轧焊管和热轧焊管,除此之外其制造工艺还有轧制,锻造,拉拔,挤压等工艺。
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.
除了上述的区分方法只在还有就是根据钢材的含碳量进行区分,含碳量在0.04%-2.3%之间的叫做铁碳合金,为了保证方管的塑性和强度一般含碳量不超过1.7%,1.5%为最佳含碳量,除此之外钢材中也可以加入铁,碳,硅,锰等元素。除了上面我们介绍的,还具有很多的区分方法,这里我们就不做详细的介绍了。
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. 标签:
