45° pipe elbow

The produced movable elbow is a metal pipe joint with ball bearing, with its specification being 1～4 and its rated working pressure being 14～140MPa( 2000psi～20000psi) It is feasible to provide various models of movable elbows used under ordinary temperature, low temperature and sulfurous gas as well as the maintenance packages. The movable elbows have 2 types: long radius elbow and short radius elbow. The major radius movable elbow has smooth drift diameter, which can minimize the resistance generated when liquid passes The resistance to erosion and corrosion of fluid for the wall thickness at the turning position of long radius elbow is better than that of short radius elbow. However, long radius elbow is also used in consideration of the limit of field installation space or lower pressure. ◆ The blank bend of movable elbow is molded on the numerical control machine, which has even wall thickness and long service life. The wall thicknesses difference at the positions of inside and outside circular arcs reaches FMC standard, and its appearance quality can match with the imported blank ◆ The movable elbow has 3-ball groove design, so that it can effectively bear overload and radial load, it is stable at the time of bearing pressure and the vibration in pipeline is smaller at the time of bearing various loads ◆ All the specifications of movable elbows are the same as the like products produced by FMC Company, and their coupling dimensions completely comply with American standards, so that they may replace the like products of FMC Company used for well cementing and fracturing equipments.
