Question #2:
The correct terminology is "Long Radius Elbow" and "Short Radius Elbow"
The difference between the two relates to the distance from the center point of the arc to the centerline of the fitting.
"Long Radius Elbows" have a radius of 1.5 times the nominal pipe size (example: a 6" Long radius Ell has a radius of 9").
"Short Radius Elbows" have a radius of 1 times the nominal pipe size (example: a 6" short radius Ell has a radius of 6")
OD: 1/8" - 24"
WT: SCH20 SCH30 SCH 40 SCH80 SCH160
Executive standards: ASME B36.10M---1996, GB8163---1999 GB8162---1999 GB3087---1999, JIS, DIN
Despite of the above standards, we can also supply seamless steel pipes with standard
Of API 5L---2000, DIN, JIS and so on,
Application:
Seamless steel pipes for low and medium pressure boiler, high pressure boiler, ship-building, liquid service, petroleum cracking, chemical fertilizer equipment, Drawing-oil-equipment and structure purposes.

In addition to the above, the material inside the pipe is of primary importance for selecting its wetted materials from the perspective of corrosion resistance. It would be no good, for example, to place dilute sulphuric acid in unlined mild steel pipes.
