Dimensional Standards of Buttweld Fitting
Types of Buttweld Fitting
Elbow
An elbow is a type of buttweld pipe fitting used to change the direction of flow in a pipeline. The most common types are 90-degree, 45-degree, and 180-degree elbows, which allow for various directional changes. Additionally, male and female elbows are used for specific joint connections. These fittings ensure smooth fluid flow and are commonly used in industries such as oil & gas, petrochemicals, and power plants.

Key Features
- Available in different angles (90°, 45°, 180°) to suit various piping layouts
- Designed for seamless or welded applications
- Manufactured in materials like stainless steel, carbon steel, alloy steel, and duplex steel
- Provides excellent resistance to corrosion and high-pressure environments
- Male and Female Elbows are used for threaded connections in certain applications
Tee
A tee is a buttweld pipe fitting used to combine or split the flow of fluids in a pipeline. It has three openings – one inlet and two outlets at 90° angles to the main line. There are two main types: Equal Tee, where all three outlets have the same diameter, and Reducing Outlet Tee, where one branch outlet has a smaller diameter than the main pipe. These fittings are widely used in plumbing, chemical, oil & gas, and water distribution applications.

Key Features
- Available in Equal and Reducing configurations for different piping needs
- Used for distributing or collecting fluid flow in various applications
- Manufactured in Stainless Steel, Carbon Steel, Alloy Steel, and Duplex Steel
- Complies with ASME B16.9 standards for industrial use
- Available in seamless and welded forms
Cross
A Cross is a buttweld pipe fitting used where four pipes meet at a common junction. It has one inlet and three outlets (or vice versa) positioned at 90° angles to each other. The two main types include Equal Cross, where all four ends have the same diameter, and Reducing Cross, where one or more branch outlets have a smaller diameter than the main line. Cross fittings are widely used in fire sprinkler systems, chemical processing plants, and high-pressure applications.

Key Features
- Used for multi-directional fluid distribution in piping networks
- Available in Equal and Reducing configurations for different applications
- Manufactured using Stainless Steel, Carbon Steel, Alloy Steel, and Duplex Steel
- Complies with ASME B16.9 and MSS SP-75 standards
- Suitable for high-pressure and high-temperature environments
Cap
A Pipe Cap is a buttweld fitting used to close the end of a pipe, stopping the flow of fluids or gases. It protects pipe ends from damage, contaminants, and environmental exposure. Caps are commonly used in plumbing, industrial piping, and high-pressure applications to provide a secure, leak-proof seal.

Key Features
- Seals the end of pipes in both permanent and temporary applications
- Available in various materials like Stainless Steel, Carbon Steel, Alloy Steel, and Duplex Steel
- Designed for high-pressure and high-temperature environments
- Manufactured according to ASME B16.9, MSS SP-75, and DIN standards
- Smooth, rounded shape to reduce stress concentration
Stub End
A stub end is a short pipe fitting used in combination with a lap joint flange to create a flanged connection that allows easy dismantling and rotation. It is commonly used in systems that require frequent disassembly for maintenance or alignment adjustments.
Lap-Joint Stub End is a specific subtype designed to work with a lap joint flange. It provides flexibility in pipe alignment and reduces the stress on bolts, making it ideal for low-pressure and non-critical applications.

Key Features
- Used with a lap joint flange to allow easy pipeline dismantling
- Helps in pipeline alignment adjustments and reduces flange bolt stress
- Available in different materials, including stainless steel, carbon steel, and alloy steel
- Lap-Joint Stub End is ideal for low-pressure and non-critical applications
- Manufactured in different lengths (short & long pattern) as per ASME B16.9
Nipple
A nipple is a short piece of pipe with male threads on both ends, used to connect two fittings or extend a pipeline. It comes in different types, including Swage Nipple and Pipe Nipple, depending on specific use cases.
Swage Nipple is used for reducing pipe diameters, typically in high-pressure applications, while Pipe Nipple is a straight pipe connector used in low to medium-pressure systems.

Sub Types
- Swage Nipple: Used to connect pipes of different diameters, mainly in high-pressure piping systems
- Pipe Nipple: A straight pipe piece with threads on both ends, commonly used for extending pipe connections
Applications of Buttweld Fittings
Buttweld pipe fittings are widely used in various industries due to their high strength, durability, and leak-proof connections. Some of the key applications include:
- Oil & Gas Industry: Used in pipelines for transporting crude oil, natural gas, and petroleum products.
- Petrochemical & Refineries: Essential for processing plants handling chemicals, fuels, and hydrocarbons.
- Power Plants: Applied in thermal, nuclear, and renewable energy sectors for steam and fluid transportation.
- Water Treatment Plants: Used in desalination and purification plants to ensure corrosion-resistant piping.
- Pharmaceutical Industry: Ensures hygienic and contamination-free fluid transportation.
- Food & Beverage Industry: Stainless steel buttweld fittings are preferred for their hygienic and corrosion-resistant properties.
- Shipbuilding & Marine: Used for seawater pipelines, ballast systems, and offshore drilling.
- Construction & Infrastructure: Essential for underground and overhead pipeline networks in cities.
