Spectacle Blinds and Fig-8 Flanges Spacer & Paddle
● A spectacle blind is a safety device used to isolate a section of line or piece of equipment when the line or equipment needs to be inspected or removed from service.
● It is different from a valve in that the blind is a permanent or long-term isolation device.
● A spectacle blind is machined from a single piece of metal that is cut to match the pipe size.
Self-Reinforced Nozzle
● Self-reinforced nozzles are nozzle necks specifically designed and forged with an extra heavy wall, attached to the thinner end of the piping.
● In operations of heavy pressure, a self-reinforced nozzle head cuts out the burden of reinforcing the nozzle or piping with additional plating or added forgings, making for a more cost-effective yet structurally sound solution.
Ring-Joint Gaskets
● Ring joint gaskets are produced from different solid metal types.
● They are used to withstand high pressures and temperatures and they are employed where corrosive agents are present.
● These gaskets are obtained by mechanically working from forged or laminated metals in one single piece.
● They are employed in the production and refining process of oil and chemical industries.
Stub Ends
● Stub ends are installed in pairs and mated together with two lap joint flanges.
● The surface of the stub end has a phonographic serrated gasket surface which prevents leakage at the joint.
● Using stub ends allows sections of the line to be opened for cleaning, inspection or quick replacement etc, without the need to re-weld.
Tube Sheets
● A tube sheet is usually made from a round flat metal plate or sheet with holes drilled to accept the tubes or pipes in an accurate location and pattern relative to one another.
● Tube sheets are used to support and isolate tubes in heat exchangers and boilers or to support filter elements.
● They can be supplied in fully machined and drilled conditions.
● Tube sheets are manufactured as per the customer’s requirements.
