For example, what are the meanings of the various parameters of the elbows DN50R1.5 and PN16, for example, what are the meanings of the elbows DN50R1.5 and PN16?

Some pipe fittings novices are not very clear about the way the elbow is expressed. Here is a sort of finishing, I hope to help everyone.


DN model nominal pass, r1.5 watch bending ratio, which is 1.5 times the nominal diameter, PN gauge pressure rating is 1.6Mpa.

The specification of the steel pipe is DN*3.5 or Ф*3.0. DN model nominal diameter, Ф-type outer diameter (usually used for seamless steel pipe), suffix digital table steel wall thickness.

If there is no material requirement, the default Q235 material or 20# steel.
