It is completely different than a valve in that the blind is a permanent or long-term isolation device. A spectacleblind is machined from a single piece of metal that is move match the pipe size, fit between two pipe flanges and needs an additional gasket during installation.

6. STUB ENDS – JAV Forgings & EngineeringPvt. Ltd. is a Stub End manufacturer in Faridabad, Haryana India. Stub ends are installed in pairs and mated along with two lap joint flanges. The surface of the stub end includes a phonographic serrated gasket surface that prevents leakage at the joint  using stubends allows sections of the line to be opened for cleaning, inspection or quick replacement etc, without the need to re-weld.

7. RING JOINT GASKETS – JAV Forgings and Engineering Pvt. Ltd. is a Ring Joint Gaskets manufacturer in Faridabad, Haryana India. Ring JointGaskets are produced from different solid metal types. They are used to stand high pressure and temperatures and they are used where corrosive agents are present. These gaskets are obtained by mechanical working from forged or laminated metals in one single piece. They are used in production and refining process of oil and chemical industries.

8. SELF-REINFORCED NOZZLES – JAV Forgings and EngineeringPvt. Ltd. is a Self-Reinforced Nozzles manufacturer. Self-reinforced nozzles are nozzle necks specifically designed and forged with an extra heavy wall, attached to the thinner end of the piping. Basically, in operations of heavy pressure, a self-reinforced nozzle head cuts out the burden of reinforcing the nozzle or piping with further plating or added forgings, making for a more cost-effective nonetheless structurally sound solution.

Stub Ends are fittings used in place of welded Flanges

JAV Forgings & Engineering Private Limited in Faridabad Haryana India discusses Stub Ends are fittings employed in place of welded flanges wherever rotating back up flanges are desired. They are also referred to as Lap Joints and Vanstone flared Laps. JAV Forgings & Engineering Pvt. Ltd. is India’s leading steel forging manufacturer and supplier of a diverse range of products. Our forging product list includes high quality of Flanges, Tube sheets, Rings and Shafts, Spectacle Blinds, Stub ends, Ring-joint gaskets and Self-reinforced nozzles.

A rotating back up flange seats itself against the back surface of the Stub end. Once bolts are added, the clamping action of the bolts presses the rotating back up flange against the back of the Stub end. The gasket surface of the Stub end then presses against a gasket and another gasket surface provides joints like standard flange joints. The seal is formed by the gasket surface of the stub end alone, the flange only provides the clamping pressure on the joint.

A stub end and a lap joint flange can be used together as an alternative way to make a flanged connection than welding neck flanges.

The two devices to be combined, in this case, are:

• The stub end, which is essentially a piece of pipe, with one end flared outwards and the other prepared to be welded to a pipe of the same bore size (NPS = nominal pipe size), material and wall thickness. The most widely used fabrication tool for stub ends is the flaring machine, which is able to flare the end of the pipe and then cuts it to length.

• A Lap Joint Flange, which is used to actually bolt the two lengths of pipe together.

BENEFITS OF LAP JOINT STUB ENDS

The use of stub ends has these two advantages:

·        Reduces the overall cost of the flanged joint

·        Facilitates the installation of the flange

STUB END TYPES

Stub ends are available in three different types, named “Type A”, “Type B” and “Type C”:

• The first type (A) is manufactured and machined to match standard lap joint backing flange (the two products have to be used in combination). The mating surfaces have an identical profile to permit a smooth loading of the flare face
• Stub ends type B are have to be used with standard slip-on flanges
• Type C stub ends can be used either with lap joint or slip-on flanges and are manufactured from pipes.

SHORT/LONG PATTERN STUB ENDS (ASA/MSS)

Stub ends are available in two different patterns:

• the short pattern, called MSS-A stub ends
• the long pattern, called ASA-A stub ends (or ANSI length stub end)

Short pattern (MSS) and long pattern stub ends (ASA)

STUB END FINISH

Stub ends can be ordered with different ends finishing:

• Beveled Ends
• Squared Ends
• Flanged Ends
• Grooved Ends
• Threaded Ends (Male Only)

Never Mess With The Difference In Cold, Warm, And Hot Forging And Here's The Reasons Why.

While the hot, glowing material is closely associated with the forging method this is not always the case. JAV Forgings & Engineering Private Limited in Faridabad Haryana India discusses the differences between forging at cold, warm, and hot temperatures and how every of these affects the finished product including high quality forgings of Mild Steel, Carbon Steel, Alloy Steel, Stainless Steel, Duplex, Super Duplex, Hastelloy, Monel, Inconel, Die-Steel and Lowtemperature Carbon Steel. JAV Forgings & Engineering Pvt. Ltd. is India’s leading steel forging manufacturer and supplier of a diverse range of products. Our forging product list includes high quality of Flanges,Tube sheets, Rings and Shafts, Spectacle Blinds, Stub ends, Ring-joint gasketsand Self-reinforced nozzles.

By forging at totally different temperatures there are distinctive benefits that can be achieved while forging working. Forging forming of metals according to temperature can be divided into cold deformation (cold forging), warm deformation (warm forging) and thermal deformation (hot forging).

1) Cold forging: refers to blanks processed below the re-crystallization temperature.
Cold forging is of high dimensional accuracy, good surface roughness, good operating conditions and high production efficiency. Therefore cold forging can replace machining sometimes. Cold forging can build metal reinforcement, improve the strength of parts. So it is applicable to aluminum and plastic parts alloy, copper and alloys, low carbon steel, medium carbon steel, low alloy steel which the deformation resistance is small under room temperature. But when cold plasticity, metal deformation resistance is big, with poor plasticity, and contains accumulation of residual internal stress, needs to be continue deformation after intermediate annealing. 

2) Warm forging: forging processed around the re-crystallization temperature.
Warm forging process is to obtain precision forgings. The warm forging can improve the precision quality of forgings, at the same time, do not have the forming force as same as cold forging. Warm forging is applicable to complicated shape of small medium carbon steel precision die forgings.

3) Hot forging: deformation temperature above the re-crystallization temperature.

In the deformation process, softening and work hardening coexist at the same time, but soften can completely overcome the effect of strain hardening, and after deformation, metal will have shaft fine grained organizations such as re-crystallization, this deformation is called thermal deformation. All these processes open die forging, hot die forging, hot rolling, heat shock, hot extrusion, belong to the thermal deformation. This is one of the most widely used types of forging process.
