Flange anti-corrosion is needed? Especially stainless steel? Actually also need anti-corrosion stainless steel flange, gold can gather nobody's perfect, no matter what products are approved by not over time in addition, if we usually don't know how to protect and maintain, so will also accelerate the stainless steel flanges rust. That what we should do in order to have the effect of corrosion? What the standard process, and see below for your analysis. What needs to be anti-corrosion, including mechanical these are all the same, even if is produced in accordance with the standard product page is not exceptional also, such as large diameter stainless steel flange will need to use the anti-corrosion measures, need to use oil or galvanizing to be carried out anti-corrosive, all of the flange is no exception. Actually means to prevent corrosion in production, in the actual construction process is after numerous cases or experience, which add steel pipe anticorrosion at production is also in the radiation crosslinked polyethylene heat shrinkable belt the anti-corrosion materials, can produce good flange, but is the main carbon steel on large flange, large flange applicable scope is oil and gas transportation engineering and chemical industry. This kind of big business is not to be careless. Are used for anti-corrosion of flange production technology is mainly manifested in forging, casting, cutting, rolling the four methods, also must perform steps, but the large flange is also divided into several types with various standard neck thread steel pipe flanges, GB/T 9115 - 2010 welded steel pipe flanges, GB/T 9116 - 2010 with neck flat welding steel pipe flanges, GB/T 9117 - 2010 with neck socket weld steel pipe flanges, GB/T 9118 - 2010 butt band neck loose tube steel pipe flanges. General large stainless steel flange cover are buried on the low, easy to corrosion at the time of installation will take heat shrinkable sleeve wrapped, its anticorrosion standards is also carried out in accordance with the national standard.
