Product Description

Companion Flanges

All the Companion Flanges are manufactured on CNC Machines.
We manufacture a total 350 variety of Companion flanges suitable for gear box (GB 40, GB 60, GB 75,,GB 1150, ZF, EATON, 9 Speed), center joint kit& differential (input,output& Thru shaft)
The flanges are tested on various pre-defined parameter to maintain accuracy.
The flanges are coated with with special coat to increase their life& also improve their aesthetics

Versatile Applications and Compatibility

Our companion flanges are designed for extensive usage within oil & gas, chemical, petrochemical, water supply, and power industries. Suitable for both pipes and tubing connections, they support raised face, flat face, or RTJ connection standards, ensuring flexibility for numerous system requirements. The ability to customize dimensions and threading means every client receives an exact-fit solution.

Durable Materials and Tested Performance

Manufactured from high-grade forged carbon steel, mild steel, or stainless steel, the flanges undergo annealing or normalization for select grades. Each flange is hydrotested up to its rated pressure, ensuring strength and safety. Surface treatments like galvanizing or anti-rust coating enhance corrosion resistance, granting a service life of up to 10 years.

Custom Packaging and Reliable Supply

To preserve quality, companion flanges are supplied in durable wooden cases or carton boxes as per customer needs. With ready stock available up to 12 inches and fast customization capacity, clients benefit from prompt and reliable order fulfillment, no matter the project size.

FAQ's of Companion Flanges:

Q: How are the inner and outer diameters of companion flanges determined?

A: The inner diameter is strictly specified by the client according to their piping requirements, while the outer diameter is matched to the appropriate flange size standard to ensure compatibility with the connected pipe and gasket.

Q: What pressure ratings can these flanges accommodate, and how is safety verified?

A: Companion flanges are designed for pressure ratings PN6, PN10, PN16, and PN25, as per design. Each flange undergoes hydrotesting up to its rated pressure, which confirms its integrity and leak-proof performance under actual operating conditions.

Q: How does the customization process work for these flanges?

A: Clients may supply detailed drawings or specifications, including dimensions, bolt pattern, thread type, and connection standard. Based on this information, the flanges are custom-manufactured and marked with size, material, and heat number to meet precise needs.

Q: What corrosion protection and material options are available?

A: Flanges are available in forged carbon steel, mild steel, or stainless steel, and are treated with processes such as galvanizing or anti-rust coatings to ensure corrosion resistance in harsh industrial environments.

Q: Where can companion flanges be used, and what industries benefit most from them?

A: These flanges serve in hydraulic, pneumatic, waterworks, gas lines, oil lines, and more. They are particularly beneficial in sectors like oil & gas, chemical, petrochemical, water supply, and power generation where robust, reliable pipe connections are critical.

Q: What are the packaging options for shipping flanges?

A: To ensure product integrity during transit, flanges are packaged in sturdy wooden cases or carton boxes as per customer or project requirements, minimizing the risk of damage.
