Long Bend
In a long bend, the centreline radius is 1.5 times the nominal size of the pipe or you can say 1.5 times the diameter of the pipe. Normally long radius elbows are used in piping as pressure loss is less as compared to short radius elbows. It required more space than a short radius elbow.
What are different types of pipe fittings?
here are variety fittings type to choose when comes to system customize. They are 90D elbow, 45D elbow, straight coupling, 3 piece union, 3 way tee, end cap, end plug, hex nipple and etc.
3 Way tee comes in T-shape and it has one inlet and two outlets. It used to combine the flow from two inlets to one outlet. Reducer is the component which helps to reduce the flow size from larger to smaller. Hex bush is another component to help in enlarges the flow from smaller to larger size.
How do you join a threaded pipe?
The connection can be threaded or socket weld end. NPT thread is the most common connection in installation as the tapered thread help make better seals. The female and male both threads compress and wedge themselves together. While BSP parallel thread is available too for certain straight regular connection such as full coupling, hex nipple and hex plug. Male threaded pipe end is needed if the threaded fittings are used for system installation.
Alternatively, welding is the simpler way to join both fitting and pipe together. The plain end pipe will insert into a recessed area of fittings before start welding. Standard fitting have the same connection for all end connection.

Superb quality product! The CS Seamless Long Bend (Schedule 40) was easy to weld and perfectly matched our piping dimensions. Withstood pressure and thermal expansion without any issue. Definitely a reliable and long-lasting fitting.
Very well-made butt welded long bends. The seamless finish gives a clean interior surface which helps reduce turbulence in fluid flow. Ideal for long-run piping networks. Packaging and delivery were good too.
We installed these CS Long Bends during a plant expansion project. The weld alignment was precise, and the bends maintained their shape even after stress testing. Excellent dimensional accuracy and strong construction.
Very strong and well-finished bends. The seamless design gives a smooth flow path with minimal pressure drop. Schedule 40 thickness provides solid strength. Only feedback — better surface finishing would make it perfect.
Outstanding quality long bends! The CS Seamless Butt Welded bends were dimensionally perfect, with smooth curvature and excellent weld-end preparation. We used them in a high-pressure steam line — zero leakage even after hydrotesting. Great product.
