High Pressure Oil Wellhead Equipment Active Elbow Long Radius / Short Radius

High Pressure active elbow of long radius & short radius according to API 16C

Introduction:

Bend is a kind of metal pipe joints with ball bearing,is in the United states FMC conpany transfer of technology digestion,absorption and production of technical innovation on the base of series products,its specifications are 1"~4",the rated work pressure of 25~140Mpa (3629 psi ~ 20000 psi), can provide the normal temperature,low temperature and sulfurous gas under the condition of using various types of elbow and repair kits.

Design features:

SJ activity elbow on the machine tool by alloy steel forgings simmer bengding forming,uniform wall thickness,long service life.Appearance quality can be comparable with imported billet;the group control of heat treatment,heat treatment production to extend the service life of the elbow body,three fairway design activities elbow,effectively withstand overload and radial load,make smooth when under pressure,under variable load,small vibration in the pipeline.Connection size completely by Amercian standards,can replace the similar foreign products,Sealers adopt synthetic rubber and metal bearing ring,pressure relief hole is designed at the same time,in the seal leakage automatically reduced pressure to prevent the cavity pressure build-up in the fairway,use security is greatly increased.By the nonyl fast reliable connection.
Development,meeting the needs of oilfield,09 year 3"-105Mpa new type structure of long radius elbow activities(see purchase details,after the model plus Y)increases the vulnerable to crosion areas on the design of wall thickness and strength,and improve the ability of resistance to crosion and prolong service life.
