What is a Flanged Weldolet?

A Flanged Weldolet is a type of branch outlet fitting used to connect a smaller branch pipe to a larger run pipe, with a flange end connection on the outlet side. The run side is welded directly to the main pipe, while the branch side uses a flange connection, allowing easy assembly, maintenance, or dismantling of connected equipment or pipelines.

Manufactured as a forged component, Forged Flanged Weldolet fittings provide superior strength, fatigue resistance, and pressure-handling capability compared to fabricated alternatives.

Compliance with ASME and ANSI Standards

At Fittinco India Private Limited, all flanged outlet fittings are produced in compliance with international standards such as ANSI B16.11 Flanged Weldolet and ASME B16.11 Flanged Weldolet requirements. These standards define pressure ratings, dimensional tolerances, material specifications, and performance criteria to ensure safety and consistency in high-pressure piping systems.

Our ASME B16.11 Flanged Weldolet products are widely accepted by EPC contractors and inspection agencies worldwide.

Types of Flanged Weldolet Offered

We manufacture and supply a wide range of High Pressure Flanged Weldolet options to suit different design and operational needs:

• Socket Weld Flanged Weldolet for compact, high-strength branch connections
• Raised Face and Flat Face flange configurations
• Standard and custom bore sizes based on client specifications

Each Forged Flanged Weldolet is precision-machined to ensure accurate alignment and optimal load distribution under pressure.

Pressure Ratings Available

Fittinco India Private Limited supplies Flanged Weldolet fittings in multiple pressure classes suitable for severe service conditions:

• Flanged Weldolet 3000 Lb for medium-pressure applications
• Flanged Weldolet 6000 Lb for high-pressure process lines
• Flanged Weldolet 9000 Lb for extreme pressure and temperature environments

The pressure class selection depends on pipe schedule, operating pressure, temperature, and fluid characteristics.

Materials & Grades

To meet diverse industrial requirements, our Flanged Weldolet Manufacturer capabilities include a wide range of material options:

Carbon Steel Flanged Weldolet

• ASTM A105, ASTM A350 LF2
• Ideal for oil & gas and power plant pipelines where strength and cost-efficiency are key.

Stainless Steel Flanged Weldolet

• ASTM A182 F304, F304L, F316, F316L
• Excellent corrosion resistance for chemical, pharmaceutical, and food-grade applications.

Alloy Steel Flanged Weldolet

• ASTM A182 F1, F5, F9, F11, F22
• Designed for high-temperature and high-pressure environments such as refineries and thermal plants.

Each Forged Flanged Weldolet undergoes controlled forging, heat treatment, and machining to achieve the required mechanical properties.

Technical Specifications

Our ASME B16.11 Flanged Weldolet products are manufactured with strict adherence to engineering requirements:

• Manufacturing Process: Hot forging from solid billets
• End Connection: Butt weld on run pipe side, flange on branch side
• Nominal Pipe Size Range: As per customer drawings and standards
• Heat Treatment: Normalized, quenched & tempered as required
• Surface Finish: Black, galvanized, pickled, passivated, or machined finish

These specifications ensure consistent performance under cyclic loads and pressure fluctuations.

Flanged Weldolet Dimensions

Flanged Weldolet Dimensions vary based on branch size, run pipe diameter, pressure class, and flange rating. Dimensional accuracy is critical to ensure proper fit-up, stress distribution, and leak prevention. At Fittinco India Private Limited, every dimension is checked during in-process and final inspection to meet ASME and ANSI tolerances. Custom dimensions and special configurations are also available on request for project-specific requirements.

Weight Details

The weight of a Flanged Weldolet depends on:

• Material grade
• Pressure class (3000 Lb, 6000 Lb, or 9000 Lb)
• Branch and run size
• Flange thickness and rating

Forged construction results in higher weight compared to fabricated outlets, contributing to superior pressure-handling capacity and longer service life. Exact weight details are provided with quotations and dispatch documentation.

Types of Degree and Branch Orientation

Flanged Weldolets are generally designed for straight branch connections at 90 degrees to the run pipe. However, custom designs can be manufactured to accommodate specific branch orientations or angular requirements based on piping layout and stress analysis.

Applications of Flanged Weldolet

Our High Pressure Flanged Weldolet fittings are widely used in:

• Oil & gas transmission pipelines
• Petrochemical and refinery process lines
• Power generation and boiler systems
• Offshore platforms and FPSO units
• Chemical and fertilizer plants
• High-pressure steam and hydraulic systems

The flanged outlet allows easy installation of valves, instruments, or secondary pipelines without extensive modification.
