3. Manufacturing Process Explained

Raw Material Selection: Uses high-purity bronze alloys with ductile iron reinforcement for increased durability. All batches undergo spectrographic analysis (per ASTM B62).
Precision Casting: Molds are created for exact flange shape, then molten alloy is poured for minimal inclusions and porosity.
CNC Machining: State-of-the-art computer numerical control (CNC) machines ensure thread and surface accuracy (±0.05mm tolerance).
Surface Treatment: Corrosion-resistant coating applied; meets ISO 9227 salt spray test for up to 1520+ hours.
Inspection & Testing: 100% hydrostatic pressure and thread integrity testing per API 598, dimensions confirmed by coordinate measuring machines (CMM).

4. Application Scenarios & Technical Advantages

Chemical Processing Plants: Excellent anti-corrosive property for aggressive fluid transport.
Water Supply & Sewage: Ideal for potable water piping as bronze is lead-free and conforms to EN1982:2008.
Petrochemicals: Robust threaded seal prevents leaks even in high-pressure environments.
HVAC and Building Services: Floor fitting design ensures strong, stable anchorage—reducing vibration-transmitted fatigue.
Mining & Metallurgy: Reinforced construction withstands heavy loads and abrasive media.

A recent 2023 reliability study indicates that bronze-threaded pipe fittings have a 33% lower failure rate compared to grey iron in municipal water networks (Ref: ASCE Journal).
