1)Installation of Horizontal Closure(Right-handed Door)
Put the closure axis horizontally. When face to the QOC lip, the drive wrench is at left, the tumble is at horizontal direction. Butt joint the barrel sub and vessel according to the weld standards, and make the inner diameter consistent.
2) Installation of Vertical Closure
Put the closure axis perpendicularly to the horizontal on the barrel which is butted joint with vessel. When the operator face to the vessel, the upright of the closure is in the back, and the drive wrench is in the front. Butt joint the barrel sub and vessel according to the weld standards, and make the inner diameter consistent.
Disassemble of QOC LidWhen installation or maintenance needs to disassemble the QOC lip, please obey the following programs:
Note:The QOC lip should be disassembled before welding the closure and the pressure vessel.
Control of Welding Deformation
1)Please make the weld line space well-distributed and consistent when the QOC and fit up with the barrel. The maximum and minimum space can’t be more than 0.5mm. The variable quantity of welding line counterparts should meet the GB150 standard.
2)The distribution of weld spots should be well-distributed and symmetric when weld the QOC and barrel.
3)When weld, adopt the symmetric method, and use low current, multi-layer welding, and control the energy of weld line to prevent from welding deformation.
When finish the weld of QOC and barrel, please take stress relief heat treatment to the weld line according to dock wall thickness, material, GB150 and other related standards.
Shield Program of Coating
1)When coat, the marked area in the following figure can’t be coated.
2)Before coating, the lock ring, security screws, tightening mechanism and sealing should be removed(They needn’t to be coat because of the stainless steel material).
3)The pin, bearing and all the thread holes should be protect from the sand
Reinstallation of QOC Lid
