SS pipe fittings are engineered for demanding industrial systems, providing reliable, corrosion-resistant connections in piping networks.
Stainless steel pipe fittings is a general term for various types of pipe connection components made of stainless steel, which are used to realize the function of piping systems by connecting, diverting, steering or blocking, and are characterized by easy installation, stable performance and durability.Each pipe fitting meets international codes (ASME, ASTM, DIN, JIS) for quality and compatibility,combining corrosion resistance with strength to allow high flow rates and long service life, widely used in piping systems that require high strength and corrosion resistance.
Stainless steel pipe fittings are components used to connect, control and change the direction of pipelines, made of corrosion-resistant stainless steel materials, widely used in piping systems that require high strength and corrosion resistance. Based on the function and shape, stainless steel fittings can be categorized into various types:
Type: Elbow, Tees, Crosses, Bends,Coupling, Elbow Reducer, Elbows Reducer, Unions, Bushings, Lateral Y Braches, Sockets, Nipples Caps,Plugs, Flanges, etc.
Size Range: ½″ through 48″ (DN15 – DN1200), or custom dimensions on request.
Wall Thickness: Sch. 5S/10S/40S/80S/160S or Schedule XXH; metric equivalents PN10–PN100.
Pressure Class: Up to ANSI Class 1500 (or PN 100) depending on material and size.
End Connections: Butt-weld (butt weld ends prepared to ASME B16.25), socket-weld, NPT threaded, or flanged (slip-on, weld-neck, blind, lap-joint as needed).
Surface Finish: Mill (rough) finish, pickled & passivated, or polished (up to 0.4 μm Ra) for sanitary applications.
Process: Push, Press, Forge, Cast, etc.
304/ 304L: General-purpose austenitic stainless; good formability and moderate corrosion resistance for many applications.
316/ 316L: Austenitic stainless with molybdenum for enhanced corrosion resistance, especially to chlorides and chemicals.Common in marine, chemical, and high-hygiene services.
Duplex 2205 (UNS S32205): Dual-phase SS with very high strength and superior resistance to pitting and stress-cracking; far exceeds 316 performance in chloride environments.
Super Duplex 2507: Higher alloy content for extreme chloride or sour service.
Other alloys: 904L (high-nickel for acids), 321/347 (stabilized for high-temp), 310S (for very high temperatures), etc.
ASME/ANSI B16.9: Wrought butt-weld fittings (elbows, tees, reducers).Covers dimensions and tolerances for ½”–48″ (DN15–DN1200).
ASME/ANSI B16.11: Forged socket-weld and threaded fittings (ANSI Class 2000 and lower).
ASTM A403/A312: Specification for austenitic stainless steel butt-weld fittings and pipes.
MSS SP-43 / SP-75: Standard practices for welded fittings (O.D. Butt-Welding) and wall thicknesses.
DIN/EN 10253: European standard for stainless butt-welded fittings.
ISO 5251: International standard for stainless steel butt-weld fittings.
JIS B2311/B2312: Japanese standards for stainless pipe fittings.
Excellent Corrosion Resistance
Stainless steel fittings resist rust, acid, alkali and chloride corrosion, extending the life of the piping system.
High Strength and Durability
High mechanical strength, suitable for high-pressure and high-temperature environments, ensuring stable system operation.
Hygiene and Safety
Non-porous and antimicrobial, meeting the strict hygiene standards of the food and pharmaceutical industries.
Multifunctional Connection
Supports multiple needs such as diversion (tee), diversion (elbow), diameter change (reducing pipe).
Flexible Installation
Quick-fit joints and compression fittings (such as DN40 compression pipe) simplify the construction process
Easy Installation and Maintenance
Standardized design, easy installation, low maintenance cost and reduced downtime.
In modern industrial and construction projects, the reliability and durability of piping systems is critical. Stainless steel pipe fittings are the preferred choice in the chemical, food processing, construction and energy industries due to their superior corrosion resistance, strength and hygienic.
