Sun Steel Co., Ltd. provides premium quality stainless fittings that cater to a wide range of needs and dimensions. One of our specialties is 316 stainless steel pipe fittings that are renowned for their durability and versatility.

Our extensive range of fittings follows the same leak-proof philosophy as our welded pipes and includes stainless steel elbows, tees, caps and flanges, among others. The superior resistance of stainless steel fittings is particularly beneficial in the chemical, water, and oil and gas sectors.

Overview of Stainless Steel Pipe Fittings

We offer a variety of fittings to meet various needs across industries, including:

  • Stainless Steel Elbows: This type is designed to change the flow of a fluid in any piping system at a predetermined angle. The most common angles are 45 degrees and 90 degrees.

  • Stainless Steel Tees: Using T-shaped fittings enables engineers to effectively split or combine flows within a larger processing system. They come in equal and reducing sizes, allowing to connect different types of pipes seamlessly.

  • Stainless Steel Reducers: They are specifically engineered to connect pipes that have different diameters so that the transition of the flow is smooth and doesn’t cause turbulence.

  • Stainless Steel Couplings: These types of stainless steel fittings are typically short sections of pipe that engineers use to connect two pipes together for optimal strength and mechanical rigidity.

  • Stainless Steel Caps: Using this variety of stainless steel fitting allows the engineer to securely seal the end of a pipe and prevent any fluid from exiting.

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

  • Stainless Steel Unions: These fittings allow for the easy disconnection of various types and sizes of pipes. This is beneficial for maintenance, replacement, and ad hoc inspections.

  • Stainless Steel 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 while preventing leaks and mechanical strain.

  • Stainless Steel Bushings: These are used to connect two pipes of different sizes. A common use is to reduce a larger fitting to a smaller pipe in a secure, leak-proof manner.

  • Stainless Steel Plugs: Stainless pieces used to close the end of a pipe and stop high-pressure flows.

  • 316 Stainless Steel Pipe Fittings: A class of fitting that is highly resistant to corrosion — designed for use in safety-critical environments with potent chemical solutions and other fluids.

Threaded Pipe Fittings

These are steel pipe fittings that are used to join threaded steel pipe without leaks or undue mechanical stress. They connect to pipes using either external or internal threads.

You can use threaded elbows to change the direction of the flow in stainless steel fittings, tees can split the flow, and nipples can create hybrid structures by joining two fittings together.

Threaded connections are essential for use in systems that require fast assembly and disassembly for maintenance and upgrades with minimal downtime.

Stainless Steel Connections and Connectors

Our pipe connector range is used and trusted by engineers around the world who require a wide array of fittings for the seamless connection of various pipes.

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 Fittings

Using 316 stainless steel pipe fittings 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 the high degree of corrosion resistance. Bushes, flanges, and elbows are all common examples of this category of fittings.

Applications of Stainless Steel Pipe Fittings

Water Treatment and Filtration Systems

Using stainless steel connections is best practice in all treatment and filtration systems because they do not taint the water. This is essential when the water is intended for human or animal consumption.

Oil and Gas Industry

Using stainless connections reduces the amount of corrosion within the system, maintaining the purity of the oil and gas in the process.

Chemical Processing Plants

A corrosion-resistant connector pipe fitting is the suitable choice when joining pipes that transport high-concentration acid solutions under high pressure and constant flow rates.

Construction and Infrastructure Projects

Robust fittings that won’t corrode chemically and then fail mechanically as a result will be able to support much stronger fluid loads.

Pharmaceutical Manufacturing

A connector pipe fitting that doesn’t corrode and release particulates is essential for maintaining the purity of a medical solution.
