Forged Ring
A Forged Ring is commonly used in various sectors such as auto, agriculture, power generation, oil field, shipbuilding, aerospace, general industrial equipment etc.
Tube sheets
Threaded Flange
Threaded Flange
A threaded flange look very similar to Slip-On flanges but the main difference is that the threaded flange has been was bored out to match a specific pipe inside diameter. The backside of this center opening is then threaded with the relevant-sized tapered pipe thread. Threaded Flanges can be used in very high pressure services and their major advantage is that they can be assembled without welding
Long Weld Neck Flange
A lap joint flange is very similar to a slip-on flange, with the main difference being that it has a curved radius at the bore and face to house a lap joint stub-end. Lap joint flanges and stub-end assemblies are typically used in situations where frequent dismantling is required for inspection. The lap joint flange itself is not welded or fixed in any way. It is free to spin for proper alignment with whatever it is joining to.
Weld Neck Flange
Weld Neck Flange
A Weld-Neck Flange or Welding-Neck Flange can be differentiated from all other types of flanges by its long tapered hub. In addition, there is also a gentle transition of thickness in the region of the butt weld that joins it to a pipe or to a fitting.
They are best suited for severe service conditions, whether loading conditions are substantially constant or fluctuating between wide limits. It is a flange with the wall thickness of the flange having the same dimensions of the matching pipe, the lighter the pipe the larger the bore, conversely, the heavier the pipe, the smaller the bore.
They are normally used for high pressure, cold or hot temperature.
Spectacle Blind Flange
Spectacle Blind Flange
A spectacle blind is a piping fitting that is used for providing positive isolation.
It consists of a pair of metal discs attached to each other. These metal discs are cut to fit between two pipe flanges and usually sandwiched between two gaskets. One of the metal discs is solid and is used for blinding or isolating the pipe, during maintenance.
The other metal disc has a circular hole to match the pipe internal diameter, as shown in the figure.
The function of this disc is to allow the flow through the pipe during normal operation.
Gear is a very important part of any machine and commonly used in the automotive sector, trucks, off-highways, aerospace, railroads, agriculture, energy, mining and material handling industries.
We manufacture all range of gears as per customer requirements.
Self reinforced nozzle
A Self Reinforced Nozzle is a nozzle neck flange that provides sufficient reinforcing in the nozzle neck without requiring additional area to be provided by excess thickness available in the shell.
Often the term self reinforced refers to a forged nozzle that has a heavy wall, transition, and a thinner end that is attached to piping (or it may have a flange). Such forgings are provided by our company using high quality forged raw material.
We manufacture these nozzles for pressure vessels designed to ANSI, ASME codes.
