• Zirconium flange

    Zirconium flange

    As a rare material, zirconium is regarded as a more precious aerospace material than titanium due to its amazing corrosion resistance, extremely high melting point, ultra-high hardness and strength and other characteristics. It is mainly exacted from zircon sand and widely used i aerospace, military industry, nuclear reaction and atomic energy fields. With the rapid development of electronics, national defense technology, information industry and emerging materials industry, zirconium chemicals are playing an increasingly important role in the high-tech fields at home and abroad, and the demand is growing rapidly.

  • Blind Flanges

    Blind Flanges

    A Blind flange is round plate which has all of the relevant boltholes but no center hole, and because of this feature this flange is used to close off the ends of a piping systems and pressure vessel openings. It also permits easy access to the interior of a line or vessel once it has been sealed and must be reopened.

  • Threaded Flanges

    Threaded Flanges

    Threaded flanges (TH flanges) are widely demanded as pipe flanges i.e called as threaded pipe flanges used in different industrial applications. They are the special type of pipe flanges which can be attached to the pipe without welding. Threaded flanges are threaded in the bore which match an external thread on the pipe. These threads are tapered in order to create a seal between the threaded flange and the pipe as the tapers approach the same diameter. Sometimes a seal weld is also used together with the threaded connection. They are available in various sizes and materials.

  • Lap Joint Flanges

    Lap Joint Flanges

    Lap joint flange is having two components, a stub end, and a loose backing flange. Stub end is butt welded to the pipe and Backing flange freely move over the pipe. The backing flange can be of different material than stub material and normally of the carbon steel to save the cost. Lap flange is used where frequent dismantling is required, and space is constrained.

  • Slip-On flanges

    Slip-On flanges

    Slip-On Pipe Flanges. As made obvious by their name, these pipe flanges slip over the pipe. They’re manufactured with an inside diameter that is slightly bigger than the pipe’s outside diameter. These attachments are connected to the pipe via fillet weld at the top and bottom of the flange.

  • Welding Neck Flanges

    Welding Neck Flanges

    The Welding neck flanges is normally referred to as the high hub flange. It is designed to transfer stresses to the pipe, thereby reducing high stress concentrations at the base of the flange.

  • Socket Weld Flanges

    Socket Weld Flanges

    A Socket Weld Flange is similar to slip-on flanges, however, socket welds have an internal recess on the inside diameter to allow for a smoother flow of the process fluid. The positive of this is that is creates a smooth bore with the proper welding and grinding. The negative of this type of flange is that it can be more expensive than a slip-on due to more intricate machining, and they can be less readily available than slip-ons due to the fact that the bottom half of the inside diameter must be made to the same schedule as the pipe that is being used. (you must specify the schedule needed) These socket weld flanges were initially developed for use on smaller sizes of pipe at higher pressure ratings.
