installation diameter
1.Installation Technologies of Preburied Prestressed Anchor Bolts of Wide Diameter Pin Roll Hinge Supports
2.There are basically three components in experimental installation of a high voltage supplier, a capillary tube with a pipette or needle of small diameter and a metal collecting screen.
3.During installation the min ambient temperature shall be above 0℃ and the bending radius of cable shall not less than 6 times of its external diameter.
4.On a loop conduit experimental installation,the pressure drop of watercut crude oil(WCCO) of Daqing 1st oil production factory with flow improver(FI) DODE added flown through a perforated tube 62 mm in diameter and 900 mm long,a pumping unit tube valve(TV) 55 mm in diameter,and a pumping unit pillar fill valve(PFV) 30 mm in diameter succesively is measured at 45℃.
5.The needie roller bearings are compact in radial structure.When their inside diameter and loading capacity are identical with that of other kinds of bearings,the outside diam-eter of tfem is smallest .So they are acceptable especially for the supprting structures which radial installation dimension is the first value.The bearings can sustain the radial loads only.
