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 a 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.
A Slip-On flange or SO flange is commonly lower in price than a weld-neck flange and so it is a
popular choices of our customers. However, customers should bear in mind that this initial cost
saving may be diminished by the additional cost of the two fillet welds required for proper installation. Moreover, weld-neck flanges have a higher life expectancy than slip-on flanges under
duress.
The slip-on flange is positioned so the inserted end of the pipe or fitting is set short of the flange
face by the thickness of the pipe wall plus 1/8 of an inch, which thus allows for a fillet weld inside
the SO flange without doing any damage to the flange face.
The back or outside of the slip-on flange or SO flange is also welded with a fillet weld.
A Socket Weld flange is very similar in appearance to a Slip-On flange, but the main difference is
the socket weld flange is bored out match a specific pipe inside-diameter.
The back side of this center opening is then counter bored to form the appropriate size socket to
take the pipe outside diameter. The diameter of the smaller bore is the same as the inner diameter
of the matching pipe.
A restriction is built into the bottom of the bore, which sets as a shoulder for the pipe to rest on.
This eliminates any restriction in flow when using a socket-weld flange.
Socket weld flanges are primarily used to make flanged joints when required in small sizes in
socket welded pipe specifications.

Blind Flange
A Blind flange is round plate which has all of the relevant bolt holes 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. Blind Flanges are commonly used in petrochemical, pipe engineering, public services & water works. We offer a range of blind flanges that are precision- engineered using best quality raw material. Our range is in compliance with set industrial standards and known for accurate size and durability. Further, our blind flanges are available in different specifications to suit the varied requirements of our clients.
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.

Crankshafts
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.
Gears
Gear
CD INDUSTRIES- PRODUCT
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.
