Stainless Steel Pipe Fittings

Sun Steel Co., Ltd. supplies high-quality fittings made of stainless steel designed for durability, precision, and leak-proof performance. The range includes 316 stainless steel pipe fittings, known for their superior corrosion resistance and versatility in demanding environments.

Our extensive range of products follows the same leak-proof philosophy as our welded pipes and includes elbows, tees, caps, and flanges, among others. 

Overview of Stainless Steel Pipe Fittings

We provide a comprehensive selection of fittings engineered for seamless integration into industrial piping systems:

• Elbows: Designed to change fluid direction at standard angles, typically 45° and 90° to minimize turbulence.

• Stainless Steel Pipe Tee Fittings: T-shaped connectors are used to split or merge flows. They are available in equal and reduced sizes.

• Reducers: They are specifically engineered to ensure a smooth transition between pipes of different diameters and prevent flow disruptions.

• Couplings: These are typically short sections of pipe used to connect two pipes together for optimal strength and mechanical stability.

• Caps: These caps seal pipe ends and prevent fluid leakage.

• Flanges: Connecting threaded pipes, valves, pumps, and any other suitable equipment is possible thanks to a choice of slip-on, weld neck, and blind steel flanges.

• Unions: Facilitate quick access, disconnection, and reassembly. 

• Nipples: Stainless steel fittings that consist of short lengths of pipe and have male threads on each end. They are commonly used to connect two fittings together.

• Bushings: These are used to connect two pipes of different sizes. Commonly used to reduce a larger fitting to a smaller pipe in a secure, leak-proof manner.

• Plugs: Close pipe ends to contain high-pressure flows securely.

• 316 Stainless Steel Pipe Fittings: Designed for corrosion resistance, they withstand harsh chemicals and extreme conditions.

Butt Welding Pipe Fittings

The butt welding pipe fittings use a conventional method to connect fittings through butt welding. We offer seamless and seamed pipe fitting options, both made from the same furnace billet, for high consistency and compatibility with the base pipe material.

They are widely used in oil refineries, chemical plants, power generation facilities, and offshore drilling rigs. Unlike threaded or socket-weld fittings, butt-welded joints offer better flow efficiency, reduced turbulence, and higher mechanical strength.

Threaded Pipe Fittings

These are steel pipe fittings that provide secure, leak-proof connections by joining internally and externally threaded pipes without welding. They are commonly used in low to medium-pressure systems, where quick installation and disassembly are essential for maintenance and system modifications.

You can use threaded elbows to change the flow direction in stainless steel fittings  (typically at 45° or 90° angles), tees to split the flow, and nipples to create hybrid structures 

They are widely used in plumbing, HVAC, fire protection, and industrial processing systems that require fast, tool-assisted assembly with minimal downtime.

Stainless Steel Connections and Connectors

The use of the correct pipe connector will prevent leaks, reduce turbulent fluid flow, and minimize wasted piping length. All of these are essential when creating a robust, efficient system that can serve the needs of the engineering and manufacturing teams.

316 Stainless Steel Pipe Fitting

Using 316 stainless steel is considered the best practice in high-pressure water treatment plants, the oil and gas industry, and construction. Additionally, stainless fittings are recommended as the standard in the chemical processing industry due to their high corrosion resistance. Bushes, flanges, and elbows are all common examples of this fitting stainless steel category.

304 Stainless Steel Pipe Fitting

As a stainless steel pipe fitting supplier, we provide 304 stainless steel fittings known for their corrosion resistance, strength, and weldability. Ideal for food processing, water treatment, and chemical industries, these stainless steel water pipe fittings withstand moisture, acids, and oxidation while maintaining structural integrity. 

Applications of Stainless Steel Pipe Fittings

Our range of options include 31254, 904/L, 347/H, 317/L, 310S, 309, 316Ti, 321/H, 304/L, 304H, 316/L, 316H. While sharing some similarities, different materials and types perform best in specific environments. Here are the key industries that rely on these fitting types.

• Water Treatment and Filtration: Reliable stainless steel pipe and fittings suppliers provide corrosion-resistant connections that prevent contamination.

• Oil and Gas Industry: Stainless fittings minimize corrosion and preserve the purity of transported oil and gas.

• Chemical Processing Plants: Corrosion-resistant fitting can withstand high-pressure acid transport, ensuring system integrity.

• Construction and Infrastructure Projects:  A durable, non-corrosive fitting can support high fluid loads without mechanical failure.

• Pharmaceutical Manufacturing: These prevent contamination and maintain the purity of medical solutions.
