ASME B16 standard includes the pipes and fittings material in cast iron, cast bronze, wrought copper and steel. ASME B16.11 (covered by ASME B16), it is used in connecting with equipment in other volumes of ASM B16 series.

Forged steel fittings named by their manufacturing processes forging, which to heat the carbon or alloy steel in a transforming temperature and modes the heated parts into the desired shape. Then use machining process to make a forged steel fittings. 

Forged pipe fittings is in high quality which with higher strength and could bear high pressure. To this fittings you should pay attention to have a uniform wall thickness since they have to be through threading process or machined to socket weld end.

• Elbows: Used to change the direction of fluid flow, available in 45°, 90°, and 180° angles.
• Tees: Allow a pipeline to branch off in different directions.
• Couplings: Connect two pipes to create a seamless flow.
• Unions: Designed for easy disassembly of a pipeline without needing to cut the pipe.
• Caps: Seal the end of a pipeline.
• Reducers: Connect pipes of different diameters to regulate flow and pressure.
• Nipples: Short sections of pipe with threads on both ends used for connecting other fittings.
• Crosses: Combine or split the flow from four directions.
• Outlets (Olets): Branch connections that are integrally reinforced. 

• Superior strength and durability: The forging process refines the metal's grain structure, making the fittings tougher and more reliable.
• Leak-proof connections: Forged fittings are known for their precision engineering, which ensures tight tolerances for a perfect, leak-free fit.
• High-pressure resistance: Their robust construction allows them to withstand high pressure and extreme conditions, making them ideal for demanding applications.
• Cost-effectiveness: While the initial cost may be higher than cast fittings, their longer lifespan and reliability often make them the more economical choice in the long run.
• Corrosion resistance: With proper galvanization or coating, mild steel fittings can resist rust and chemical damage. 

• Oil and gas: Used for transporting oil and natural gas in pipelines and other equipment.
• Power generation: Found in steam and water piping systems in nuclear and conventional power plants.
• Chemical and petrochemical plants: Handle corrosive substances under high pressure.
• Construction: Integral to HVAC and plumbing systems.
• Firefighting: Connect pipes and control water flow in fire protection systems.
• Water treatment: Used for water distribution and wastewater management.

The Threaded Pipe Fitting is a type of forged pipe fitting designed to be screwed onto the ends of pipes or other fittings, creating a secure and leak-proof connection in high-pressure piping systems.

Our threaded pipe fittings are available in various types, such as threaded 90 degree elbows, couplings, nipples, unions, and branch outlets.  These fittings are made from stainless steel, carbon steel, alloy steel, and super duplex stainless steel.  They are available in different pressure ratings, including 2000lbs, 3000lbs, and 6000lbs.  The common threaded types include NPT, BSPT, and BSPP.

A piping system's most important components are forged fittings, known for their strength, durability, and reliability. They are created through a forging process, where metal is heated and shaped under extreme pressure to form the desired fittings. At Nik-San Pipefit Engineering Co., we specialize in providing high-quality forged fittings designed to meet the rigorous demands of various industries.

All of the steel forged fittings that Special Piping Materials supplies are corrosion resistant and designed to operate in high-pressure environments.

We have a wide variety of fittings available, both in stock and bespoke made including:

• 45° elbows
• 90° elbows
• Straight and reducing tees
• Couplings

Forged steel fittings are available in both threaded and socket weld end connections.

Carbon Steel Pipe Nipple?

CS pipe nipple is an iron-carbon alloy with a carbon content of 0.0218% to 2.11%. Contains a small amount of phosphorus, sulfur, silicon, and manganese. carbon steel hex nipples have high hardness levels. Corrosion is susceptible if not protective coating. carbon steel barrel nipple suitable for heavy-duty applications in machinery, industrial applications, and construction. CS nipple material needs regular maintenance to prevent rust. These nipples are made by seamless and welded pipe. Carbon steel threaded nipple used for schedule 40 & schedule 80 conforms to ASTM A106 Grade B. These pipe nipples are generally used to connect pipes in various low-pressure systems. Carbon steel pipe nipples have excellent yield and tensile strength. The maximum working pressure is 1.5 MPa. The operating temperature of this nipple is between -20 degrees C to120 deg C.

Products are packaged to ensure that there is no damage during transit. In case of exports, the standard export packaging is done in wooden cases. All forged fittings are marked with Grade, Lot No, Size, Degree, and our trademark. On special requests, we can also, make custom marking on our products.

At Metro Forge , all fittings and flanges are subject to strict inspection at each stage of the production process, from starting material purchasing to product dispatch. They are visually examined for conformity to ASTM, ASME, MSS, DIN, EN, and JIS codes and standards. Upon request, official certified Inspection Agencies can be called in to witness the material reports, dimensions and quality conformity of products.

The standard specifies the dimensions, tolerances, ratings, materials, chemical composition and tensile properties, heat treatment, notch toughness, manufacturing and marking of quality butt welded pipe fittings for NPS 60 and smaller. Normally for NPS14 and smaller butt weld pipe fittings referred to ASME B16.9.

The allowable internal pressure ratings for straight seamless steel pipe (or welded steel pipe with a joint coefficient of 1.0) of equivalent grades and diameters and wall thicknesses shall be calculated in accordance with the rules established in the applicable section of ASME B31 and in accordance with the fittings designed in this standard specification.

According to MSS SP-75, all fittings made shall be designed to support the field hydrostatic pressure test at a pressure level . This pressure level is equivalent to the pressure level required to form an hoop stress. Based on the Barlow formula, the hoop stress is equal to the specified minimum yield strength for pipe of equivalent grade and wall thickness under the condition of no damage, leakage or failure.
