Alloy G-30 (UNS N06030) is a Ni-Cr-Fe corrosion-resistant alloy with alloying additions of molibdenum, tungsten, copper and niobium. Generally resistant to oxidizing environments, it's extremely resistant to phosphoric acid (P2O5) and thus used widely in the production of agrichemical fertilizers. It can be seen as a low-carbon variant of alloy G, with improved weldability (it's less prone to heat-affected zome carbide precipitation and hot-cracking), and ductility.Used in phosphoric acid plants, sulphuric acid service, nitric acid service, pickling operations, petrochemical operations, fertilizer manufacture, pesticide manufacture, gold extraction and nuclear waste processing.
Blanks Figure 8 Blanks Flange is a pipe fitting, which is mainly used for easy maintenance. You can know its specific shape by painting the upper part of the "8" black. It is half a blind plate and half an iron ring. It is often used in pipeline flanges that need to change the process. The main materials are carbon steel, stainless steel, and alloys. It can be selected according to the pipeline pressure level and pipeline medium. It is usually used on pipelines with larger diameters. Usually, one end of the flange is used to occupy the spacing to keep the pipeline unobstructed. When necessary, it is replaced with a blind plate of the same thickness at the other end to cut off the pipeline. Avoid forced expansion of the pipeline due to temporary replacement of other blind plates, affecting the entire system.
