Product Description

FLANGE

This industrial flange delivers high-strength rigid connection, reliable gasket-assisted sealing and flexible on-site assembly. 
It meets strict zero-leakage requirements and has passed CE certification. It fits water, oil, steam and chemical pipeline systems, with a long-stable service life. Moreover, we supply WCB/SS304/SS316L material options and multiple face & connection types to match your requirements.

Product Description

1. Ultra-low Leakage Rate & Long Service Life
Stable tight-connection performance guarantees minimal leakage under rated working pressure. Manufactured strictly in accordance with standard Q/Zs78.2, this threaded flange features precisely machined inner thread. Well-matched inner cavity structure effectively prevents seepage of water, oil, gas and various chemical media.
Superior Anti-Corrosion Sealing Matching 
Fabricated from AISI 304 stainless steel, the flange body delivers good resistance against acid, alkali and rust erosion. It maintains stable sealing under continuous medium impact, avoiding pipeline backflow, liquid overflow and unexpected pressure loss within fluid systems.
Long-Term Industrial Wear Resistance 
The integrated one-piece machined structure resists wear and dirt accumulation. It keeps stable connection performance after long-time pressure cycle aging test, without deformation, thread slipping or loose joints, achieving far longer service life than ordinary carbon-steel fittings.
Optimized for Diverse Industrial Pipelines 
Standard inner thread and bolt-hole layout enables fast alignment and reliable connection with mating pipes and valves. Smooth inner flow channel lowers flow resistance. It adapts to outdoor, chemical, hydraulic and plumbing conditions, cutting later-stage maintenance and replacement costs.

_{2.Ultra-low Leakage & Stable Sealing}
Integral one-piece forged structure eliminates welding seams for reliable sealing under high-pressure working conditions. Standard inner bore supports instrument sampling and pressure-tapping service. Proper flange-gasket mating effectively prevents seepage of oil, gas and chemical media, securing stable operation of instrument piping systems.
Superior Anti-corrosion & Anti-scouring Capacity 
Manufactured from AISI 304 / 316 stainless steel and qualified by salt-spray test. It delivers outstanding resistance to acid, alkali and fluid erosion. Maintains stable connection under long-term medium impact and avoids unexpected system pressure loss.
Excellent Durability for Harsh Conditions 
Solid forged body withstands frequent pressure fluctuation without deformation or cracking. Precision-machined smooth surface resists dirt accumulation and abrasion. Compared with conventional welded branch connections, this nipo-flange provides improved structural reliability for long-un service.
Professional for Industrial Instrument Pipelines 
Standard flange bolt holes enable fast installation. The top tapered port adapts well to pressure gauges and transmitters. Smooth inner bore reduces flow resistance. Widely applied in chemical, petroleum, power and pharmaceutical instrument piping to lower later-stage maintenance expenses.
Core Advantages 
This forged nipo-flange features high pressure resistance, excellent corrosion performance and dependable sealing. Adopting universal standard dimensions, it solves common leakage and durability risks of welded branch joints, serving as critical component for process-instrument piping.
