Olets

Product Overview

Olets Stockist & Supplier in India

Olets are branch connection fittings designed to create outlet connections from a main pipe to a smaller branch pipe. As a reliable Olets Stockist in India and Olets Supplier in India, we supply a wide range of branch outlet fittings for high-pressure, high-temperature, and critical piping systems.

Olets provide a compact and reinforced branch connection compared with conventional fabricated tee arrangements. They are selected based on header pipe size, branch size, wall thickness, material grade, pressure rating, and the type of end connection required.

With an established presence since 1985 and ISO 9001:2015, ISO 14001:2015 and ISO 45001:2018 certifications, Metal-Link supports olet requirements with material traceability, inspection documentation and project-based supply.

Olets Specifications

Product Range

Different Types of Olets

As an experienced Olets Supplier in India, we supply branch connection fittings for process equipment, pressure systems, piping installations, offshore platforms, refineries, and industrial facilities. Our product range includes:

Weldolet

High-Strength Butt-Weld Branch Connection

Weldolets are among the most commonly used olets for reinforced branch connections. They are designed to be welded directly onto the run pipe and provide a smooth transition to the branch pipe.

Key applications include:

• ✓Oil and gas pipelines
• ✓Petrochemical plants
• ✓Refineries
• ✓High-pressure process piping
• ✓Power generation systems

Sockolet

Compact Socket-Weld Branch Fitting

Sockolets are designed for socket-weld branch connections, generally used for smaller pipe sizes. The branch pipe is inserted into the socket and welded around the joint.

They are commonly used in:

• ✓Small-bore piping
• ✓Instrumentation lines
• ✓Chemical plants
• ✓Utility piping
• ✓Process systems

Threadolet

Threaded Branch Outlet

Threadolets provide a threaded outlet connection and are generally selected where welding of the branch pipe is not preferred.

Typical applications include:

• ✓Low-pressure piping
• ✓Utility services
• ✓Instrument connections
• ✓Drain and vent lines
• ✓Temporary or accessible piping systems

Elbolet

Branch Connections on Pipe Elbows

Elbolets are specifically designed to create branch outlets from pipe elbows. Their contoured base matches the curved surface of the elbow, helping achieve a suitable branch connection without using a fabricated fitting arrangement.

Latrolet

Lateral Branch Connection

Latrolets are designed for branch connections at an angle, commonly 45 degrees to the run pipe. They are useful where piping layout or flow requirements make a perpendicular branch connection unsuitable.

Nipolet

Combined Nipple and Outlet Connection

Nipolets combine the function of an outlet fitting with an extended nipple section. They are commonly used for vents, drains, gauges, instruments, and small process connections.

Sweepolet

Smooth Transition Branch Outlet

Sweepolets are designed with a smooth and gradual transition between the run pipe and branch connection. This geometry can help reduce localized stress concentration and is useful in demanding piping systems.

Material Grades

Common Materials for Olets

As an experienced Olets Supplier in India, material selection can be matched with the parent pipe to maintain compatibility in welding, corrosion resistance, thermal expansion, and mechanical performance.

Design Data

Standards and Specifications for Olets

Olets are commonly manufactured and supplied according to applicable piping and branch connection standards.

Selection Criteria for Olets

When selecting an olet for a piping system, several factors should be considered:

Material Data

Manufacturing and Performance Characteristics

Manufacturing Process

Olets are typically manufactured through forging processes to ensure proper material grain structure and mechanical properties. The manufacturing process generally includes:

• ✓Selection of certified raw material matching pipe specifications
• ✓Forging to required shape
• ✓Heat treatment where applicable
• ✓Machining of branch outlet and connection surfaces
• ✓Surface finishing
• ✓Dimensional inspection
• ✓Non-destructive testing where required
• ✓Material testing and documentation
• ✓Final marking and identification

Performance Characteristics

Olets provide several advantages in piping system design and construction:

• ✓Reinforced branch connection without additional welded reinforcement pads
• ✓Compact installation requiring less space than fabricated tee assemblies
• ✓Reduced welding requirements compared with fabricated branch connections
• ✓Consistent mechanical properties through controlled forging processes
• ✓Material compatibility when matched with parent pipe grade
• ✓Suitable for high-pressure service when properly selected and installed

Installation Considerations

Proper installation of olets is important for joint integrity and system performance:

Frequently Asked Questions

What types of olets do you supply?

We supply Weldolet, Sockolet, Threadolet, Elbolet, Latrolet, Nipolet, Coupolet, and Sweepolet in various materials, sizes, and schedules according to MSS SP-97 and project requirements.

What is the difference between a Weldolet and a Sockolet?

A Weldolet is designed for butt-weld branch connections and is typically used for larger pipe sizes in high-pressure systems. A Sockolet is designed for socket-weld connections and is generally used for smaller bore piping where the branch pipe is inserted into the socket and fillet welded around the joint.

When should a Threadolet be used instead of a welded olet?

Threadolets are selected where welding is not preferred or practical, such as in low-pressure utility services, instrument connections, drain and vent lines, or temporary piping installations. They provide a threaded branch connection without requiring welding equipment or procedures.

What materials are olets available in?

Olets can be supplied in carbon steel, alloy steel, stainless steel, duplex steel, nickel alloys, Inconel, Monel, and other materials depending on service requirements. Material selection should match or be compatible with the parent pipe material for proper welding and service performance.

What standards apply to olets?

Olets are commonly manufactured according to MSS SP-97 for integrally reinforced forged branch outlet fittings. They must also comply with applicable piping codes such as ASME B31.1 for power piping and ASME B31.3 for process piping, along with relevant ASTM material specifications and ASME Section II material requirements.

Can you supply material test certificates with olets?

Yes. Olets can be supplied with Material Test Certificates (MTCs), chemical analysis, mechanical test results where applicable, PMI reports, dimensional inspection reports, non-destructive testing documentation, and third-party inspection certificates as required by project specifications.
