When entering new questions, KudoZ askers are given an opportunity* to classify the difficulty of their questions as 'easy' or 'pro'. If you feel a question marked 'easy' should actually be marked 'pro', and if you have earned more than 20 KudoZ points, you can click the "Vote PRO" button to recommend that change.
How to tell the difference between "easy" and "pro" questions:
An easy question is one that any bilingual person would be able to answer correctly. (Or in the case of monolingual questions, an easy question is one that any native speaker of the language would be able to answer correctly.)
A pro question is anything else... in other words, any question that requires knowledge or skills that are specialized (even slightly).
Another way to think of the difficulty levels is this: an easy question is one that deals with everyday conversation. A pro question is anything else.
When deciding between easy and pro, err on the side of pro. Most questions will be pro.
* Note: non-member askers are not given the option of entering 'pro' questions; the only way for their questions to be classified as 'pro' is for a ProZ.com member or members to re-classify it.

Mitre Elbows:
• These are usually used for low pressure, low temperature non critical services having 14” inches and above. They are economical as compared to elbows in higher sizes and hence preferred.
• Mitre bends are usually fabricated at site out of pipe by cutting and re-welding spools as shown in Fig. 7. The Figure is for 5 piece 4 weld mitres. The change in direction at every weld is 22 1/2 °. We may also have 4-piece 3-weld mitre where change in direction at every weld would be 30°. Usually 5 piece 4 weld mitres are preferred in order to have smooth flow.
A Miter bend is a bend which is made by cutting pipe ends at an angle and joining the pipe ends. A true miter bend is a 90 degree bend made by cutting two pipes at 45 degrees and joining them by welding
