Manufacturing Process

Industry Applications

Offshore Drilling Systems

Custom flanges maintain leak-proof joints under wave shock, pressure cycling, and equipment tilt.

Aerospace Testing Rigs

Low-tolerance flanges support secure closure across high-frequency vibration and rapid thermal shifts.

Cryogenic Pipelines

Special flange geometries seal low-temperature flows without stress cracking or contraction gaps.

Nuclear Cooling Loops

Units meet specialty codes and material specs required for radioactive fluid isolation.

Semiconductor Fabrication Plants

Electropolished flanges with ultra-flat faces support inert gas and high-purity fluid flow. 

Defense Hardware Assemblies

Custom profiles align with non-standard enclosures, maintaining bolt load under impact or shock.

Specialty & Custom Flanges

Engineered Around Specs

Application-Matched Profiles

Each flange matches the assembly design, covering unique face dimensions, hole patterns, or special sealing faces.

Controlled Material Selection

We machine flanges from alloys specified for corrosion, vacuum integrity, or strength-to-weight needs.

Dimensional Precision Delivery

Custom flanges meet strict tolerances with CAD-backed programs and calibrated inspection tools.

Having Doubts? Our FAQ

Check all our Frequently Asked Questions

Can I send part drawings or spec sheets for custom flange production?

Yes, we accept 2D or 3D files in STEP, IGES, or PDF formats. Our team reviews design limits, tolerances, and material callouts before sharing manufacturing feasibility. We also assist in adjusting specs to match production-ready formats. 

What is the typical range of sizes and ratings Frigate supports for special flanges?

We handle flanges from DN15 up to DN2000, covering PN, Class, and non-standard pressure ratings. This includes ring-type, weld-neck, or compact options not found in standard catalogs. We validate fitment across multiple gasket and bolting patterns. 

Can I request a flange based on performance environment, not just dimensions?

Yes, we help define flange geometry and surface prep based on thermal, vacuum, or corrosive conditions. That includes choosing neck length, face finish, and special coatings. Every build links back to real operating loads and connection behavior. 

How does Frigate control repeatability for custom flanges in multi-unit orders?

We lock all flange parameters through part-specific CAD files and NC programs. Tooling paths stay unchanged across batches unless revision approval is shared. Final inspection follows the original approved dimensions using calibrated fixtures. 

Can you support flanges that need to match existing overseas equipment specs?

We can reverse-match flanges using legacy drawings, sample parts, or equipment interface data. International bolt patterns and special thread combinations can be recreated. Our team has handled specs originating from EU, US, and East Asian sources.
