Stainless steel threaded pipe fittings

Stainless steel threaded pipe fittings are a type of metal connecting parts used to connect different pipe sections in pipelines or pipe systems. Their main bodies are made of stainless steel and have internal or external threads (such as NPT (American Standard conical thread) or BSP (British standard thread), and can be installed without welding through rotary connection. It has the advantages of corrosion resistance, stable structure and easy disassembly and assembly, and is widely used in the connection of pipelines or pipe systems in the petroleum, chemical, food processing and water treatment industries.

Classification of stainless steel threaded pipe fittings products

Threaded elbows: Mainly used to change the direction of pipes. Common types include 45° and 90° elbows, which can be directly bent from stainless steel pipes or made through forging and other processing methods.
Three-way: It is used to achieve branch diversion or convergence.
Reducer: It is used to connect pipelines of different diameters. Common types include concentric reducers and eccentric reducers.
Joint: It is used for straight-through connection and detachable operation, mainly a short pipe used to connect two fittings, valves or other pipe components.
Pipe cap: Used for pipe blocking.
Adapter: Connects interfaces of different specifications or standards, such as NPT-BSP, etc.

Material and specification standards

CENTRAL STEEL produces various types of stainless steel threaded pipe fittings, providing customers with better products and higher quality.

Common materials: AISI 304 and the more corrosion-resistant 316(or 316L), the latter containing molybdenum and having stronger resistance to pitting corrosion.

Manufacturing standard:

Forged thread/socket welds: ASTM A182 + ASME B16.11.
Threaded fittings (castings) : ASA B16.3 (dimension) + ASA B2.1 (thread).
The dimensions of plugs and elbows are often defined in accordance with MSS SP-114 /ASME B16.9.
Thread types: NPT (American Standard Taper Thread), BSP (British Standard Thread), ISO 7-1, etc.

Pressure rating: Common 150 lb (low pressure), 3000/6000 class (high pressure industrial application).

Performance and Advantages

Corrosion resistance: The stainless steel anti-oxidation protective layer is repairable and rust-proof, suitable for Marine, chemical, food and other environments.
High strength and high-temperature resistance: Suitable for high-pressure (up to several thousand psi) and high-temperature environments.
Strong hygiene: Smooth surface without pores, easy to clean, meeting food-grade and pharmaceutical standards.
Easy installation: No welding required, can be threaded or disassembled, and maintenance is quick.
Diversified interfaces: Supports different thread standards and diameters, with high adaptability.

Application scenarios

Oil and gas industry: Used for transporting corrosive media, gases and liquids.
Chemical equipment: Applied to corrosion-resistant and high-pressure conveying pipelines.
Food, beverages and pharmaceuticals: Due to its strong hygiene, it is often used in CIP systems and clean environments.
Water treatment and seawater systems: Remarkable resistance to chloride corrosion.
HVAC (Heating, Ventilation and Air Conditioning) system: The preferred material for cold and hot water and refrigerant pipelines.

Summary

Stainless steel threaded pipe fittings are widely used in the oil and gas, chemical, food and other industries due to their strong corrosion resistance, high temperature/high pressure resistance, solid structure, convenient installation and hygiene advantages.
