Industrial Fittings

Alloy Steel Fittings

Fittings generally produce change in geometry and its application include

• Change in direction of piping
• Alter piping dimensions
• Terminate piping line
• Brings pipes together (make the branch from main pipe run).
• Reference standard ASME B 16.9
• Use of these fittings are generally not restricted in most of the piping systems

Features:

• Alloy Steel contains substantial quantities of elements other than carbon such as nickel, chromium, silicon, manganese, tungsten, molybdenum, vanadium and limited amounts of other commonly accepted elements such as manganese, sulfur, silicon, and phosphorous.
• Addition of such alloying elements is usually for the purpose to increase hardness, strength or chemical resistance.
• Pipe Fittings made of alloy steel have exceptional performance properties.
• These are generally developed for energy-related applications involving oil and gas drilling and are subjected to stresses in machine parts.
• Robust construction
• Durability
• High strength

3- Insert tubing into a fitting body. Be sure tubing is bottomed on a fitting shoulder.

4- Lubricate threads and assemble nut to fitting body.

5- Tighten nut hand tight. From that point, tighten with a wrench the number of turns indicated in the chart below.

Forged Fittings are manufactured from materials consisting of forgings, bar, SMLS tubular products which shall conform to the requirement for WP SMLS manufacturing materials of ASTM Fitting specifications A 234, A 403, A 420, A 815, B 366 or ASTM forging specifications A 105, A 182, A 350, B 283, B 462, B 564

1. Socket welding

· Reference ASME B 16.11

· Size frequently limited to NPS ≤ 4” in following classes

· Not used in severe cyclic conditions and in services where corrosion is accelerated in the crevices.

· No weld metal can enter Bore

· Easier alignment of smaller lines than Butt weld fittings

· Tacking procedure is not necessary, therefore reducing welding time. No chance of leakage

2. Threaded

· Non-toxic, Environment-friendly and cost-effective as no welding is involved.

· Chances of leakage are comparatively higher, generally not used where leaks cannot be tolerated.

· Reference ASME B 16.11

· Size frequently limited to NPS ≤ 4” in following classes

· Used in services where regular maintenance is required.

· All fittings are threaded both internal(Female) and external(Male) with American National Standard Pipe Threads ASME B1.20.1 (NPT) or British Standard Pipe Threads (BSP)

Duplex Pipe Fittings are the widely chosen fittings, used in critical conditions of industries. Widely demanded in the industries of oil & gas, petrochemical, and many others, these fittings are designed with the assurance of dimensional accuracy, resistance against corrosion and high tolerance capacity. Designed in the options of threaded and socket weld end connections, the pipe fittings have either buttweld, seamless or welded construction. These have the ability to bear a wide range of pressure level with excellent inertness to toxic chemicals. Best suited for highly critical applications where leakage can be hazardous, the pipe fittings are used in boilers, desalination plants and brewing tanks. There are minimum burrs at the edge of the fittings with excellent accuracy in dimensions even in the high-temperature range. Due to their high yield strength, these are widely demanded in the petrochemical industry, nuclear industry, paper & pulp industry and defense sector.
