Welcome to Solitaire Fittings, your trusted Carbon Steel Fitting Supplier. We offer a wide range of Carbon Steel Fittings that are strong, durable, and perfect for many types of industries. Whether you need CS Fittings for plumbing, oil and gas, or power plants, we have the right solutions for you.
What Are Carbon Steel Fittings?
Carbon Steel Fittings are parts used to connect pipes together in a system. They help control the direction, flow, and pressure of liquids or gases. These fittings are made from carbon steel, which is a mix of iron and carbon. Carbon steel is well-known for being tough and long-lasting.
There are different types of CS Fittings, including:
- Carbon Steel Pipe Fittings
- Carbon Steel Buttweld Fittings
- Carbon Steel Forged Fittings
- CS Seamless Butt Weld Fittings
- Carbon Steel Welded Pipe Fittings
- CS Butt Weld Pipe Fittings
At Solitaire Fittings, we manufacture and supply all these types of carbon steel fittings with top quality and precision.
Advantages of Using Carbon Steel Fittings
Still wondering why you should go for Carbon Steel Buttweld Fittings or Carbon Steel Welded Pipe Fittings? Here are the key benefits:
- High Strength: Carbon steel is incredibly tough, making it suitable for heavy-duty applications.
- Cost-Effective: Compared to stainless steel, carbon steel fittings are more affordable while offering great performance.
- Easy to Install: With proper tools and guidance, these fittings are easy to connect, weld, and maintain.
- Excellent Temperature and Pressure Resistance: They can handle extreme conditions without failing, which is why they’re widely used in critical systems.
Types of Carbon Steel Fittings We Offer
➤ Carbon Steel Buttweld Fittings
These fittings are welded directly onto the pipe. They are great for high-pressure systems and give a smooth flow inside the pipe. Our range includes:
- Elbows (90°, 45°)
- Tees (Equal & Reducing)
- Reducers (Concentric & Eccentric)
- Caps
- Crosses
We offer CS Butt Weld Pipe Fittings in different sizes and schedules (pipe thickness levels) to fit your project.
➤ Carbon Steel Forged Fittings
Forged fittings are made by shaping the metal under high pressure. They are very strong and used in high-pressure and high-temperature systems.
Types of Carbon Steel Forged Fittings include:
- Socket Weld Fittings
- Threaded Fittings
- Couplings
- Unions
- Bushings
- Plugs
➤ CS Seamless Butt Weld Fittings
These fittings are made without any seams or joints, which gives them extra strength and leak-proof performance. They are used where safety is the top priority.
➤ Carbon Steel Welded Pipe Fittings
These fittings are made by welding steel plates or coils. They are cost-effective and perfect for lower-pressure systems.
Applications of Carbon Steel Fittings
Carbon Steel Fittings are used across many industries because of their strength and versatility. Here are some common applications:
- Oil & Gas Pipelines – Safe and reliable flow of oil and natural gas
- Power Plants – Handles high pressure and heat without damage
- Water Supply Systems – Used in both residential and industrial plumbing
- Chemical Industry – Withstands harsh chemicals and extreme environments
