Our online quoting platform and broad range of capabilities make it easy to source custom parts for both prototyping and production
Special bolt-circle patterns, hole spacing, flange faces (RF, FF, RTJ, blind, slip-on, weld-neck etc.) — for non-standard pipes / special equipment or retrofit projects.
As a professional CNC machining supplier, BeatPro factory's custom precision flanges with hub/neck, extended flanges, long-weld-neck flanges, large-diameter flanges or special face finishes — for pumps, compressors, tanks, vessels, offshore plant, chemical, marine and power applications etc.
Machined mating surfaces — to accurately control flatness, concentricity and surface finish for leak-free sealing, the stud can always transfer reliable mechanical tightening load as well as service life.
Materials, flange type and machining are per industrial-grade standards and practices.
| Material / Alloy | Common Use Cases | Treatment / Finish Options |
| Carbon Steel, Alloy Steel (such as 42CrMo / 4140) | High-profile, high-strength pipe, pressure systems, lifting equipment | Heat treatment, nitriding / phosphating, mechanical machining surface finish |
| Stainless Steel (e.g. 304, 316) | Aggressive media, marine / seawater, aggressive chemical, water & wastewater, hygiene-sensitive systems | Passivation / polishing / standard finishing |
| Duplex / Special Alloys or Exotic Alloys (available on request) | High-temperature, corrosive or specialized environments | Custom CNC machining + surface treatment, according to customer's requirements |
We'll begin with a forged or billet blank if necessary, and perform the necessary CNC milling/turning/drilling/boring to achieve accurate bolt-circle dimensions, flange face flatness, hole alignment and any special features. Quality control check includes dimensions, bolt-hole circle accuracy, face flat and surface material finish and traceability.
BestPro high quality Custom Precision Flanges are ideal for:
These systems are used in high pressure lines in petrochemical, chemical plants, power generation and industrial processing plants
Pump service, compressors, tanks where special mounting or flange configuration is needed
Withstands corrosion common in marine / seawater / wastewater systems. These are heavy duty flanges.
Upgrade, Repair & Retrofit for when standard flange size or pattern does not fit
True customization — flange sizes, bolt pattern, face type, materials to your drawing / requirements
Material options — carbon / alloy, stainless, high performance / specialty alloys
Machining quality — machined or forged, precise surface finishing and geometry control
QC & traceability — material certificate, dimensional report, inspection record available
Heavy duty industrial usage, since pressure, corrosion, temperature and sealing reliability are considerations
