Explore our flagship ANSI/ASME, EN, DIN, and specialized threaded flange solutions engineered for zero-leak performance in civil, commercial, and industrial applications.
Navigating modern commercial plumbing and heavy-duty industrial fluid conveyance through advanced forging, precision threading, and anti-corrosion metallurgy.
In the high-stakes sectors of modern civil engineering, mega-structure commercial plumbing, and heavy process manufacturing, fluid containment systems depend heavily on specialized joining components. Among these critical connections, the Threaded Urinal Flange serves as an indispensable bridge between sanitary fixtures and soil-waste piping networks. Concurrently, industrial threaded flanges, weld neck flanges, socket weld flanges, and blind flanges maintain the structural integrity of high-pressure utility lines, petrochemical pipelines, and HVAC infrastructures.
A threaded urinal flange—often specified in cast bronze, heavy-wall forged brass, or corrosion-resistant stainless steel—is engineered to secure wall-hung or floor-mounted urinal fixtures while providing a gas-tight, liquid-tight seal against sewer gas leaks, liquid pooling, and structural wall degradation. Unlike conventional plastic strainers or lightweight cast iron collars, premium metal threaded urinal flanges incorporate precision National Pipe Taper (NPT) or British Standard Pipe Taper (BSPT) internal threads, enabling seamless mechanical engagement with waste lines, neoprene gaskets, and closet wax rings.
At Shanxi Yuxin Casting & Forging Co., Ltd. (YUXIN), founded in 1992 in Dingxiang, Shanxi—widely recognized as China's premier "Hometown of Forging"—we synthesize over three decades of metallurgical mastery to manufacture high-integrity flange solutions. Whether supplying ASME B16.5 high-pressure industrial flanges or precision-machined commercial threaded urinal flanges, YUXIN adheres strictly to rigorous international standards including ASME, ANSI, EN 1092-1, DIN, JIS, and specialized plumbing codes (UPC/IAPMO, CSA B125.1).
In commercial sanitation networks (airports, sports arenas, shopping malls, high-rise office towers), premature urinal flange failure results in catastrophic sub-floor water damage, foul sewer gas odor leaks, and severe structural maintenance costs. Premium threaded urinal flanges solve this through two critical engineering parameters:
Understanding regional sourcing trends, regulatory compliance shifts, and the critical role of China's forging clusters in global supply chains.
Driven by strict ADA compliance, UPC (Uniform Plumbing Code) requirements, and green building standards (LEED v4), North American buyers demand certified lead-free brass (AB1953) and stainless steel threaded urinal flanges alongside ASME B16.5 Class 150/300 forged steel pipe flanges for industrial installations.
European markets emphasize PED 2014/68/EU compliance, EN 1092-1 standard conformity, and EN 10204 3.1 material certification. Environmental directives mandate zero-leak sanitary waste connections and ultra-durable industrial flanges capable of enduring aggressive media.
Rapid mega-infrastructure growth, airport expansions, and luxury hospitality projects demand high-capacity, heavy-duty brass and bronze threaded urinal flanges resistant to high ambient temperatures and saline water flushing systems, as well as NACE sour-service industrial flanges.
Rapid urbanization, transit hub construction, and industrial manufacturing plants rely heavily on Dingxiang Shanxi forging clusters for high-volume OEM stock supply, offering unbeatable cost-to-performance ratios without sacrificing mechanical integrity.
Over 33 years of direct forging experience, audited quality management, and complete in-house manufacturing control in Dingxiang, Shanxi.
Shanxi Yuxin Casting & Forging Co., Ltd. was established in 1992 in the Zhuangli Enclave Industrial Zone of Dingxiang County, Shanxi—the historic center of China's precision forging industry. Unlike trading companies or third-party resellers, YUXIN operates a fully integrated, state-of-the-art manufacturing facility spanning 10,000 tons of annual flange capacity and 2,000 tons of specialized forged components.
From initial billet cutting, electric induction heating, hot die forging, and controlled heat treatment (normalizing, annealing, tempering, solution treating) to precision multi-axis CNC machining, tapping, and surface coating—every single component is executed inside our owned facilities. This single-site production control guarantees 100% heat number traceability from raw ingot to final delivered package.
Audited quality management system certified by TÜV CERT, operating in full compliance with AD 2000-Merkblatt W0 / TRD 100 and the European Pressure Equipment Directive (PED 2014/68/EU).
Every shipment is accompanied by Mill Test Certificates documenting chemical heat analysis, mechanical tensile/yield strength, impact values (-40°C testing), UT/MT non-destructive examination, and hardness logs.
Full engineering capability to produce non-standard flanges, custom threaded urinal rings, stub ends, tube sheets, and specialized rings up to 3,000 mm diameter directly from customer CAD/PDF drawings.

Where YUXIN threaded urinal flanges and industrial forged components deliver zero-maintenance operation worldwide.
In high-traffic international airport terminals and modern commercial skyscrapers, wall-hung urinals experience constant heavy use. YUXIN brass threaded urinal flanges ensure high physical strength against cantilevered force, preventing waste line cracking, sub-floor water damage, and costly building downtime.
Municipal sanitation facilities utilize our heavy-duty bronze and stainless steel threaded urinal flanges due to their exceptional immunity to aggressive uric acid salt buildup, harsh sanitizing chemical cleansers, and biological hydrogen sulfide corrosion.
For upstream wellhead manifolds and refinery process piping, YUXIN supplies ASME B16.5 Weld Neck and RTJ Blind Flanges forged from ASTM A105 and A182 F316L, engineered to withstand extreme pressures up to 2500 Class and sour NACE gas service.
Shipbuilding contractors and crane manufacturers rely on YUXIN CNC-drilled tube sheets, expansion joint flanges, and forged rings designed for heat exchangers and hydraulic power packs operating under intense salt-spray marine environments.
Pioneering smart IoT sensors, anti-microbial surface treatments, and sustainable zero-carbon metallurgy.
Future iterations of commercial threaded urinal flanges are integrating micro-encapsulated moisture sensor channels directly into flange collar grooves, enabling smart building management systems (BMS) to detect microscopic seal weepage long before physical ceiling leaks occur.
YUXIN is developing ultra-thin hydrophobic and anti-bacterial PVD nanocoatings for internal flange threads. These advanced coatings prevent uric acid crystallization, scale deposition, and bacterial biofilm growth inside critical sanitary drain paths.
By shifting to closed-loop electric induction forging furnaces, 100% scrap metal recycling, and automated waste heat recovery systems in our Shanxi plant, YUXIN reduces carbon intensity per ton of forged steel by up to 35%, assisting global EPC partners in meeting net-zero building targets.
