Product Parameters

Specification Parameters	Details
Nominal Pipe Size	2 inches (According to ASME B36.10M, the outside diameter is approximately 60.3 mm)
Material	The material is usually 304 and 316 stainless steel, in accordance with ASTM A240/A240M standards
Fitting Types	There are several types of elbows, including 90-degree long-radius elbows, which have a radius of about 1.5 times the nominal pipe size, such as 3 inches (76.2 mm). Short-radius elbows have a radius of about 1 times the nominal size, such as 2 inches (50.8 mm). There are also 45-degree elbows. Tees can be equal tees or reducing tees. The connection style can be made into threaded or socket weld type.
Pressure Rating	For 304 stainless steel fittings, it can generally withstand up to 150 psi (10.34 bar) at room temperature (around 20°C). 316 stainless steel fittings handle about 150 psi (10.34 bar) at room temp, same as the 304 ones.But where they really shine is in hot conditions or places with lots of corrosion-they hold up way better there.This makes them a solid pick when pairing with 2 inch stainless steel pipe fittings in tough setups.
Manufacturing Standards	Manufacturing generally complies with ASME B16.9 for factory - made wrought steel butt - welding fittings and ASME B16.11 for forged steel fittings. Welding processes follow AWS D1.6 if applicable.
Thread Standards	Threaded fittings usually conform to ASME B1.20.1, such as NPT threads.

Chemical Composition And Standard

Stainless Steel Type	Compliance Standard	Chemical Composition
304 stainless steel	ASTM A240/A240M	Contains 18-20% chromium and 8-10.5% nickel
316 stainless steel	ASTM A240/A240M	Includes 10-14% nickel, 16-18% chromium, and 2-3% molybdenum – often used for making 2 inch stainless steel pipe fittings

Functions of Stainless Steel Pipe Fittings

Stainless steel pipe fittings play a crucial role in the functioning of pipelines. They help to:

Connect pipes of different shapes and sizes

Change the direction of flow in a pipeline

Reduce or increase the diameter of a pipeline

Seal the end of a pipeline to prevent leakage

Allow for easy maintenance and repair of pipelines

Types of Stainless Steel Pipe Fittings

Elbow fittings – It is used to modify the track of the line of the pipe which is available in 45.90 and 180 degree angles.

Tee fittings – It is used to join three pipes together by forming a T shape. It’s mostly utilized for fluid and gas transportation.

Reducer fittings – It is used to connect pipes of different shapes and diameters for smooth access of the water flow from the bigger pipes to the smaller pipes or the inverse.

Coupling fittings – It is used for better protection from leakage or to avoid the further consequences of fluid leakage

Cross fittings

It is preferred to unite four pipes together and make a cross shape. It is also used in gas distribution.

Union fittings

It is used to smooth the functioning of pipes for better maintenance or repair. It also contains two parts through which simple disconnection can be done.

Nipple fittings

It is used in case the pipes are closed together, it allows us to reconnect two pipes together.

Flange fittings

It is used to attach taps and pipes to other appliances like tanks or pumps generally used in industrial sectors.

Cap fittings

It is used as a lock that prevents water leakage by closing the end of a pipe.

Bend fittings

It is used to make a bend in the pipes for easy access or diversion towards the route.

Uses of Stainless Steel Pipe Fittings

Oil and Gas

Stainless steel fittings are generally used in oil and gas, where pipelines are unprotected from critical climatic conditions and destructive fluids. They oppose deterioration, degradation, and humid temperatures, making them perfect for use.

Chemical Processing

Stainless steel fittings are also used in chemical refineries, where pipelines are unshielded to harsh chemicals and warm temperatures. They are opposed to corrosion and chemical attack, guaranteeing a longer lifespan for the pipeline.

Food and Beverage

Stainless steel fittings are widely used in the food and beverage industry, where pipelines must be clean and uncontaminated. They are easy to clean and maintain and are unaffected by bacterial growth.

Grades and Specifications of Stainless Steel Pipe Fittings

Choosing the right grade of stainless steel for pipe fittings is essential for ensuring durability, resistance to corrosion, and compatibility with the intended application. Each grade offers unique benefits:

304 Stainless Steel: One of the most commonly used grades, 304 stainless steel provides excellent corrosion resistance, making it ideal for general-purpose applications in food and beverage processing, water treatment, and residential plumbing.
316 Stainless Steel: Containing molybdenum, 316 stainless steel offers enhanced corrosion resistance, particularly against chlorides and acidic environments. It is widely used in marine applications, chemical processing, and pharmaceutical industries.
321 & 347 Stainless Steel: These grades are stabilized with titanium (321) or niobium (347), preventing carbide precipitation during high-temperature exposure. They are ideal for applications in heat exchangers, aerospace, and power plants.
317L Stainless Steel: With a higher molybdenum content than 316, 317L stainless steel provides even greater corrosion resistance, especially against sulfuric acid and other harsh chemicals. It is frequently used in chemical processing plants.
310 Stainless Steel: Designed for high-temperature applications, 310 stainless steel maintains strength and oxidation resistance up to 1150°C, making it suitable for furnaces, kilns, and heat-treating equipment.
904L Stainless Steel: A super austenitic stainless steel, 904L is highly resistant to acidic environments and aggressive corrosion. It is commonly used in applications involving sulfuric acid, seawater, and extreme chemical exposure.
