Carbon steel socket weld fittings are forged components designed for high-pressure piping systems, joined by inserting pipe ends into sockets and welding for strength. ​

Common Standards

These fittings conform to ASME B16.11, available in pressure classes 3000, 6000, and 9000 lbs, with types including elbows, tees, couplings, unions, caps, and reducers. Key grades include ASTM A105 for general use and A234 WPB for welded applications, ensuring compatibility with carbon steel pipes.​

Material Properties

Carbon steel grades like A105 feature carbon content of 0.35% max, manganese 0.6-1.05%, and yield strength around 250 MPa minimum, providing good toughness and weldability.

Stainless steel threadolets are forged branch connection fittings with NPT threaded outlets, welded directly onto run pipes to create reinforced outlets without full tees, ideal for high-pressure piping systems.​

Dimensions

For Class 3000 1/2" threadolet: height (A) 34 mm, width (B) 30 mm, thread engagement (C) 24 mm. A 1" size measures A 38 mm, B 38 mm, C 30 mm; run pipe compatibility from 3/4" to 48" NPS.​

Specifications

Made from ASTM A182 F304/316 per MSS SP-97 standards, pressure classes 3000/6000 LB, sizes 1/8" to 4" branch outlets. Full/reducing configurations ensure self-reinforcing strength up to 10,000 psi.​

Carbon steel olet fittings are self-reinforced branch connections welded onto main pipes for creating outlets, available in types like weldolet (butt-weld branch), sockolet (socket weld), thredolet (threaded), and nipolet (nipple weld).​

Specifications

Made from ASTM A105 or A234 WPB carbon steel per MSS SP-97 standards, sizes cover run pipes from 1/2" to 48" NPS with branch outlets up to 50% of run size. Pressure classes include 3000, 6000, and 9000 LB, with seamless or forged construction.​

Dimensions

For a standard weight weldolet on 3" run with 1" outlet, height measures around 34 mm and width 30 mm. Reducing sizes consolidate; e.g., 6" run accepts up to 3" outlets with specific contours for full penetration welds.​

Carbon steel sockolets are socket weld branch connection fittings made from low-carbon steel (typically ASTM A105), used to create reinforced outlets from larger run pipes to smaller branches in high-pressure small-bore piping systems. They feature a socket end for pipe insertion and fillet welding, providing self-reinforcement per MSS SP-97 standards, complementing prior elbows, U-bends, 3D bends, caps, unions, reducers, and flanges in CS/MS setups.​

Key Features

Classes 3000#/6000#/9000# handle up to 10,000 PSI; sizes feature run pipes up to 48" NPS with branches 1/8"-4". Dimensions include height (A: 19-43mm), groove depth (C: 15-25mm).​

Specifications

Butt weld base to header, socket weld branch; tolerances ensure fit with matching schedule pipes.​

IBR alloy steel elbows meet stringent Indian Boiler Regulations (IBR) for high-pressure steam and boiler applications. Manufacturers like Ace Alloys LLP produce these fittings in grades such as ASTM A234 WP5, WP9, WP11, and WP91 for superior strength in elevated temperatures.​
Material GradesCommon IBR-approved alloy steels include WP1, WP5, WP9, WP11, WP12, WP22, and WP91, offering creep resistance up to 600°C. These elbows feature precise chemistry with chromium, molybdenum, and vanadium for oxidation and corrosion resistance. Ace Alloys LLP certifies them with IBR Form III C and NDT reports.​
SpecificationsAvailable in seamless (up to 24" NB) or welded construction (up to 48" NB), sizes range from 1/2" to 48" NB in SCH 10 to XXS. Angles include 30°, 45°, 60°, 90°, with long radius (1.5D) or short radius (1D) bends per ASME B16.9. Pressure ratings suit 150-2500 LBS classes.

Stainless steel weldolets are forged branch connection fittings designed for butt-welding to the run pipe, providing a contoured, self-reinforcing outlet for smaller branch pipes in high-pressure systems.​

Dimensions

Standard weight weldolets follow MSS SP-97 charts; for a 2" size: height (A) 1-1/2", width (B) 3-1/2", depth (C) 2-9/16", bore (D) 2-1/16", weight ~1.5 lbs. Larger 6" models reach A 2-3/8", B 8-1/2", up to 14 lbs.​

Specifications

Manufactured from ASTM A182 grades like F304/316/ F51 duplex stainless steel, available in STD/XS/SCH160 classes for run pipes up to 60" NPS and branch sizes 1/8"–24". Ensures integral reinforcement exceeding code requirements.​

Applications

Ideal for petrochemical, oil/gas, and power plants needing strong, leak-proof branches on large headers without reducing pipe strength.​

Weldolets are self-reinforced butt-weld branch connection fittings used to create a 90-degree outlet from a larger run pipe to a smaller branch pipe in high-pressure piping systems. They provide integral reinforcement, reducing stress concentrations compared to tees, and are commonly made from stainless steel grades like 304 or 316 for corrosion resistance in industries such as oil & gas and chemicals.​

Key Features

• Forged construction with beveled ends for strong butt welds to the header pipe.

• Available in sizes from 1/2" to 36" for branch outlets, with pressure ratings up to 6000 PSI.​

• Thicker than standard tees, ensuring compliance with ASME B16.9 and MSS SP-97 standards.​

Applications

Ideal for high-temperature/pressure lines where space is limited or tees are impractical, such as pump discharges or process piping. In stainless steel setups, they pair well with reducers, flanges, and ER/CR fittings for seamless B2B supply chains.​

Carbon steel threadolets are forged, threaded branch fittings welded to a main pipe (run) to create outlets, following MSS SP-97 standards for self-reinforced connections in high-pressure systems. ​

Specifications

Made from ASTM A105 carbon steel, available in Class 3000, 6000, or 9000 pressure ratings with NPT threads. Run pipe sizes span 1/2" to 48" NPS, branch outlets from 1/8" to matching run size, in full or reducing configurations.
