Class 150 Flanges
We have gained an expertise in manufacturing and offering a high quality range of Class 150 Flanges that have high degree of dimensional accuracy, corrosion resistance. We have fabricated these ranges that comply with relevant industry standards. Further, these are bolted to each other and are joined to the piping system by welding or threading. We have raised their faces by 1/16 inches and have flat faces. We also provide customization as per the requirement and suitability of the clients. These are highly demanded in food, chemical and pharmaceuticals industries.
