K. H. Trading Company

Kolkata, West Bengal

We are dealing as an exclusive Supplier and Manufacturer of MS Flanges. The principle of a flange is to use a mechanical force (exerted by the bolts) to pre-load the gasket sufficiently, so that when internal pressure (end cap force) is applied, there is enough contact stress between the flanges and gasket to maintain a seal. The flange itself needs to be connected to the pipe. This is usually achieved by welding, though threaded and other weldless connections also exist. We can manufacture all the above types of Flange or as per requirement of the buyer. We also manufacture Bulb Cotter Pins and Flat type Cotter Pins as Indian Railway Drawings and as per Buyers Requirement. Range :

• Weldneck

We manufacture a wide range of Bolts And Nuts as per IS :1363-92. A screw, or bolt, is a type of fastener characterized by a helical ridge, known as an external thread or just thread, wrapped around a cylinder. Some screw threads are designed to mate with a complementary thread, known as an internal thread, often in the form of a nut or an object that has the internal thread formed into it. Other screw threads are designed to cut a helical groove in a softer material as the screw is inserted. The most common uses of screws are to hold objects together and to position objects. A nut is a type of hardware fastener with a threaded hole. Nuts are almost always used opposite a mating bolt to fasten a stack of parts together. The two partners are kept together by a combination of their threads' friction, a slight stretch of the bolt, and compression of the parts. In applications where vibration or rotation may work a nut loose, various locking mechanisms may be employed: Adhesives, safety pins or lockwire, nylon inserts, or slightly oval-shaped threads. Fabricated from quality metal, our Bolts And Nuts are well-acclaimed for their superior quality and durability. These Bolts And Nuts are available in different specifications to meet the requirements of the clients. Features :
