What are the differences between 1D, 1.5D and 2.5D elbows?

Intuitively, short-radius elbows are much shorter than long-radius elbows, and their bend radius is very abrupt. Long-radius elbows are the most commonly used and are generally the default. Long-radius elbows are used in high-pressure or high-flow applications. For solids transport pipelines with stringent resistance requirements, larger-radius elbows are used. Applications of Short Radius

How to choose the right stainless steel tee product

There are many connection methods for stainless steel tees, such as: clamping, welding, groove, ring pressing, etc. Different connection methods can also achieve firm connection in connection, and resolutely prevent the problem of loose pipes and water leakage. Among them, the double clamping connection method has outstanding advantages, the cost of pipe fittings is relatively low, no open flame is required for installation and use, the safety of the construction site is maintained, the pipe fittings are firmly connected and sealed, and the connection technology is mature and relatively stable.
