A customized titanium flange is a high-precision connecting component engineered from titanium alloys such as Grade 2, Grade 5 (Ti-6Al-4V), and Grade 7, manufactured to your exact drawings, dimensions, and performance requirements. These flanges are roughly 45% lighter than stainless steel and are available in an OD range of 100 – 250mm (or totally bespoke), with a polished surface finish and a density of only 4.51 g/cm3. We provide precisely machined titanium flanges that give dependable sealing integrity for the most demanding applications in non-standard sizes, unusual pressure ratings and special face combinations.

· Exceptional corrosion resistance — the self-regenerating titanium oxide film resists saltwater, wet chlorine gas, hydrochloric and sulfuric acids
· High strength-to-weight ratio — up to 45% lighter than stainless steel with comparable or superior tensile strength
· Shock absorption — low modulus of elasticity reduces stress in high-vibration environments
· Zero-leakage sealing — surface finish controlled to Ra 0.8–1.6μm for reliable gasket contact
· Long service life — decades of performance in aggressive chemical and offshore environments

Offshore Oil & Gas and Desalination: Titanium flanges are utilised in subsea manifolds, heat exchangers and SWRO high pressure pump lines where chloride heavy saltwater would kill normal steel flanges within months.
Chemical Processing (Chlor-Alkali) Joining electrolytic cells and pipe systems carrying wet chlorine and hypochlorites, titanium provides decades of service life and greatly decreases MRO downtime costs.
Aerospace and Marine Defense: Hydraulic systems and propulsion units require weight-optimized customized titanium flange with complex geometries that fit within tight airframes and resist galvanic corrosion during continuous saltwater exposure.

Finding a titanium flange that suits your plumbing system is seldom an easy task. Off-the-shelf parts just can’t address non-standard diameters, severe pressure classes and unusual shapes.
That is where we come in. Baoji Huacan New Metal Materials Co., Ltd. is located in Baoji, China's "Titanium Valley," with 10+ years of titanium machining experience and 40+ high-precision CNC machines on the shop floor.
We provide properly fitting flanges according to your CAD designs or technical criteria without compromising sealing performance and without extra weight.

Production begins with certified titanium ingots, which are remelted in a vacuum arc remelting (VAR) process to achieve chemical uniformity and low impurity levels.
The forging is done on a 4000 tonne hydraulic press that imparts a fine grain structure to the flange, improved fatigue resistance and exceptional dimensional integrity. Every year we produce more than 3,000 tonnes.
After forging, each flange goes through multi-axis CNC precision machining. Our 40+ CNC lathes and machining centers produce tight-tolerance features, including bolt hole patterns, sealing faces, and complex geometries based directly on your submitted drawings.

BJHC applies a multi-stage inspection process across every production batch.
Raw materials are verified by spectrometer for chemical composition before entering production. Dimensional inspections are performed in process at each step of the machining process to ensure tight tolerances are maintained.
Finished flanges are checked using CMM, callipers and surface roughness gauges. Ultrasonic testing may reveal interior cavities or fractures. Mechanical properties — tensile strength, yield strength, and hardness — are tested against ASTM, AMS, and DIN standards before shipment.
