Threaded Flange Manufacturer & Supplier in Mumbai

Nishra Overseas manufactures and supplies Threaded Flange in Mumbai for piping systems where a detachable flanged connection is required without welding the flange directly to the pipe. A threaded flange has a machined internal thread that engages with the external thread of a compatible pipe, allowing the flange to be installed without a welding operation at the pipe-to-flange joint. This makes threaded flanges useful for selected piping, utility, maintenance, and process applications where threaded connections are specified.

Threaded flanges can be supplied in stainless steel, carbon steel, alloy steel, duplex and other suitable material grades according to the application and purchase specification. Selection depends on nominal pipe size, pressure class, material grade, thread designation, temperature, fluid service, facing arrangement and applicable dimensional standards. Nishra Overseas is an ISO 9001:2015 certified manufacturer, stockist and exporter with more than 25 years of industry experience and supplies industrial products from Mumbai to international markets.

Threaded Flange Manufacturer in Mumbai

As a Threaded Flange Manufacturer in Mumbai, Nishra Overseas supplies threaded flanges according to applicable flange standards, material specifications, and customer requirements. The manufacturing route generally involves suitable forging or flange-forming operations followed by controlled machining to achieve the required outside diameter, thickness, bolt-hole pattern, facing and bore configuration.

The internal thread is a critical feature of the product. Thread machining must provide the required thread form, pitch, depth and dimensional compatibility with the mating pipe. Where specified, thread requirements such as NPT or another approved thread designation are produced according to the applicable project or dimensional standard.

Manufacturing and finishing operations can include:

Material selection and verification
Forging or suitable flange forming
Heat treatment where required by material specification
CNC or precision machining
Bolt-hole drilling
Flange facing
Internal thread machining
Dimensional inspection
Visual and surface inspection
Final documentation and traceability

Material selection is based on service conditions rather than using a single grade for every application. Stainless steel may be selected for corrosion resistance, while carbon or alloy steel grades may be used according to pressure, temperature and mechanical requirements.

Threaded Flange Supplier in Mumbai

Nishra Overseas is a Threaded Flange Supplier in Mumbai serving EPC contractors, fabricators, OEMs, engineering companies, consultants, procurement teams and industrial buyers. Supply can be arranged according to required material, grade, nominal size, pressure class, facing, thread specification, quantity and inspection requirements.

For project procurement, buyers can specify MTC requirements, material traceability, PMI, third-party inspection and other quality documentation where required. Product configuration and delivery are finalized against the purchase order, drawing or project specification rather than assuming a standard configuration for every application.

Threaded Flange Exporter in Mumbai

Nishra Overseas also supports international procurement as a Threaded Flange Exporter in Mumbai. The company states that it exports its industrial product range to more than 50 countries across markets including the USA, Europe, Middle East, Asia and Australia. Export orders can be supported with applicable material certificates, inspection documentation, traceability information and suitable packaging according to project requirements.

Threaded Flange Specifications

Features of Threaded Flange

Threaded flanges are selected when a mechanical flanged connection and threaded pipe interface are required. Important characteristics include:

Internal threaded bore for compatible threaded pipe
No pipe-to-flange welding required
Suitable for selected piping and utility services
Available in multiple material grades
Different pressure classes according to applicable standards
Compatible with bolted flange connections
Precision-machined thread and facing surfaces
Suitable for applications requiring easier flange removal
Available with project-specific inspection documentation
Material traceability can be provided according to order requirements
Suitable for selected maintenance and installation applications
Configuration can be matched to project piping specifications

Threaded flanges should be selected carefully for high-pressure, high-temperature, cyclic or severe-service applications because thread geometry and joint configuration directly influence suitability.

Applications of Threaded Flange

Threaded flanges are used where piping systems require a bolted flange connection while retaining a threaded pipe interface. They can be used for equipment connections, utility lines, selected process piping, maintenance installations and piping systems where welding is restricted or undesirable.

Typical applications include:

Utility and service piping
Instrumentation-related piping
Water and general industrial services
Compressed-air systems
Equipment and valve connections
Process support systems
Plant maintenance installations
Selected low- and moderate-pressure piping services

The appropriate material and pressure class should be verified against the operating fluid, temperature, pressure and applicable piping specification.

Standards & Specifications

ASME B16.5 is a key dimensional and pressure-temperature standard for pipe flanges and flanged fittings within its applicable size range and pressure classes. For threaded flange applications, the flange dimensions, pressure class, facing and other requirements should be confirmed against the applicable edition and purchase specification.

Thread requirements may also reference an applicable pipe-thread standard such as ASME B1.20.1 when a compatible NPT configuration is specified. Material requirements are separately governed by the applicable ASTM material specification, depending on the selected grade.

The applicable standard should always be confirmed from the engineering drawing, piping class, purchase order or project datasheet.

Quality Standards & Testing of Threaded Flange

Quality control focuses on material identity, dimensional accuracy, flange geometry and thread compatibility. Depending on the order requirements, inspection may include:

Raw material verification
Chemical composition analysis
Mechanical testing
Hardness testing where applicable
Dimensional inspection
Bolt-hole and flange-face inspection
Thread inspection
Visual inspection
PMI testing where required
Heat and lot traceability
Third-party inspection where specified
Mill Test Certificate documentation

Nishra Overseas states that it operates with ISO 9001:2015 certification and provides original Mill Test Certificates, PMI testing, third-party inspection acceptance and material traceability through heat and lot marking.

How to Select the Right Threaded Flange

Before purchasing a threaded flange, buyers should confirm:

Material: Match the flange material with the pipe, fluid and corrosion environment.
Grade: Specify the required ASTM or project material grade.
Size: Match the nominal pipe size and flange dimensions.
Pressure: Select the required pressure class based on design conditions.
Temperature: Check material suitability at operating and design temperature.
Thread: Confirm thread type, designation, pitch and compatibility.
Facing: Specify RF, FF or another required facing.
Standard: Confirm the applicable flange and material standards.
Inspection: Define MTC, PMI or third-party inspection requirements.
Quantity: Provide project quantity and delivery schedule.

These details help prevent thread mismatch, dimensional incompatibility and incorrect material selection.
