API 6A/6B Flanges
India’s Leading 3000psi 6A/6B Blind Flange, 2000psi 6B Weld Neck Flange, 3000psi 6A Blind Flange, 5000psi 6BX BL Flange, API 6A/6B High Pressure Steel Flange Manufacturer & Supplier in India.
Kanak Steel & Engg Co. is an eminent manufacturing, exporting, supplying, trading and distributing unit of API 6A Flanges / API 6B Flanges, which are used to clean off the ends of piping, valves and stress vessel openings.
They are again and again utilized by manner in their maximum enormous benefit, that is it is able to be used for unanticipated conditions and in very plenty impulsive areas wherein welding is hazardous. Duplex Steel API 6A Flanges are through and big utilized in commercial vessels and on electricity plants, due to their noteworthy benefits. They are to be had in all stress lessons and provide an incredible replacement to attach one-of-a-kind pipe sizes. Available in one-of-a-kind configuration, they’re quite plenty appropriate to attach pipe and tubing parts.
It additionally gives more than a few benefits which includes durability, reliability and near tolerances. The most important feature of flange is to offer a get entry to a pipe line for metering of drinks or gases. Alloy Steel API 6B Flanges is packed collectively among a pair of flanges whilst its miles being established in a pipe line and the whole assembly is known as an orifice flange blending. They are used instead of the usual pipe flanges whilst glide nozzle or orifice plate is being used. It is a skinny plate (normally disk-shaped) with a hole (normally within the middle) this is usually used to distribute the burden of a threaded fastener, which includes a screw or nut.
It is a couple of interlocking discs, created from steel or plastic, typically utilized in vicinity of buttons to lock apparel and for comparable purposes. Different kinds of snaps may be connected to material or leather-based through riveting with a punch and die set unique to the kind of rivet snaps used (putting the punch with a hammer to splay the tail), sewing, or plying with unique snap pliers. Inconel Alloy API 6B Flanges is normally fabricated from steel, and characterized through a helical ridge, called a male thread (outside thread) or simply thread, wrapped round a cylinder.
