Common Types We Can Manufacture

We can manufacture according to ASME B16.11, MSS SP-83, and MSS SP-97 standards, or provide customized products for you.

Threaded 90-deg Elbow

Threaded 90-degree Elbow changes the direction of flow in a threaded pipe system at a 90-degree angle, commonly used to connect two pipes perpendicularly.

Threaded 45-deg Elbow

Threaded 45-degree Elbow alters the direction of flow at a 45-degree angle, providing a smoother change in direction than a 90-degree elbow, thus minimizing friction and pressure loss.

Threaded Cross

Threaded Cross connects four pipes at a single point, featuring one inlet and three outlets (or vice versa), arranged in a cross shape to facilitate multiple pipeline connections.

Threaded Tee

Threaded Tee connects three pipes at a 90-degree angle, allowing for redirection of flow from one main line to two branch lines, or vice versa.

Threaded Street Elbows

Threaded Street Elbow features a male thread on one end and a female thread on the other, enabling direction change in a piping system while accommodating different pipe sizes or fittings.

Threaded Coupling

Threaded Coupling connects two pipes of the same diameter in a straight line with female threads on both ends, ensuring a secure and tight connection without the need for welding.

Threaded Half -Coupling

Threaded Half-Coupling has female threads on one end, used to connect a single pipe to a larger piping system, often in tight spaces where a full coupling is not feasible.

Threaded Cap

Threaded Cap seals the end of a threaded pipe, stopping the flow of fluid or gas or serving as a temporary closure during maintenance.

Threaded Square Head Plug

Threaded Square Head Plug with a square head and male threads closes the end of a threaded pipe or fitting, providing easy installation and removal using a wrench.

Threaded Hex Head Plug

Threaded Hex Head Plug features a hexagonal head and male threads, designed to seal pipe ends and provide a convenient gripping surface for tools.

Threaded Round Head Plug

Threaded Round Head Plug with a round head and male threads, is used to close pipe ends in low-pressure applications, allowing for manual installation or removal.

Threaded Hex Head Bushing

Threaded Hex Head Bushing has male threads on the outside and female threads on the inside, used to connect pipes of different diameters, with the hexagonal shape facilitating easy tightening or loosening.

Threaded Flush Bushing

Threaded Flush Bushing has a flush profile with male threads on the outside, designed to reduce the size of a pipe opening and provide a smooth, unobtrusive connection.

Threadolet

Threadolet has internal threads that connect to a branch pipe via threading at a 90-degree angle to the main pipe.

Application of Threaded Fittings

SSM manufactures threaded fittings , which are used across various industries and applications to connect, redirect, or control the flow of fluids or gases in piping systems.

Plumbing Systems: Threaded fittings are commonly used in residential and commercial plumbing to connect pipes, faucets, and fixtures, allowing for easy installation and maintenance.
Oil and Gas Industry: In this sector, threaded fittings are utilized for connecting and redirecting pipelines, as well as in wellhead equipment and processing facilities, where they help manage high-pressure fluids.
Chemical Processing: Threaded fittings are used in chemical plants to handle various chemicals and fluids, providing reliable connections in processing and storage systems.
Water Treatment: These fittings are employed in water treatment plants for connecting pipes and valves in filtration, purification, and distribution systems.

Advantages of Threaded Fittings

Our threaded fittings are popular not only because of these advantages,

Ease of Installation: Easy to assemble and disassemble without the need for special tools or welding, making them ideal for quick repairs or modifications.
Cost-Effective: Generally cheaper than welded fittings because they do not require welding or skilled labor.
Reusability: Can be easily removed and reused, which is cost-efficient for temporary or frequently changed systems.
No Welding Needed: Suitable for environments where welding is impractical or not allowed, such as in explosive atmospheres or when dealing with specific chemicals.

Disadvantages of Threaded Fittings

SSM reminds you that while threaded fittings offer many advantages in specific applications, they also have some drawbacks. When selecting our fittings, please consider the following issues:

Leakage Risk: More prone to leaks compared to welded or flanged connections, especially under high pressure or in vibrating conditions.
Limited Pressure and Temperature Range: Generally not suitable for very high-pressure or high-temperature applications.
Corrosion at Threads: Threads can be susceptible to corrosion over time, especially in harsh environments.
Size Limitation: Typically limited to small-diameter pipes, not suitable for larger pipeline systems.
Alignment Issues: Proper alignment is necessary for a tight, leak-free seal, and repeated assembly/disassembly can cause thread wear.

The Materials of Threaded Fittings We Can Provide

SSM’s threaded fittings are manufactured from controllable raw materials with strict quality control. We commonly supply fittings made from the following materials:

Carbon Steel Threaded Fittings

SSM commonly provides carbon steel threaded fittings, which are commonly used for various applications due to their strength and cost-effectiveness. They are typically used in applications where high strength and good wear resistance are required.

Stainless Steel Threaded Fittings

SSM commonly provides stainless steel fittings including ASTM A182 F304 and F316, which are known for their corrosion resistance, making them ideal for applications in harsh environments.

Alloy Steel Threaded Fittings

SSM commonly provides alloy steel socket welding fittings, such as ASTM A182 F11 and ASTM A182 F22, which are designed to handle high pressures and temperatures, often found in industrial applications.

Nickel Alloys Threaded Fittings

SSM commonly provides nickel alloy threaded fittings such as Inconel 600, 625, 718, Hastelloy C-276, and Monel 400/K500. which are known for their exceptional resistance to extreme temperatures and corrosive environments.
