Abstract Along with the science and technology development, the automated technology utilization is more and more widespread, already permeated the production life the majority of processes.

The fast attachment marine riser series product, is United offshore construction Co. CONHW to hit the well work necessary special-purpose product for the sea oil field. Has analyzed this company new product (after *SR-30, SR-24, SR-20, *SR-16, the SR-13 3/8 series) the production craft, the treating processes and the production efficiency, design a set primarily to include the guide rail, the driving gear, the chain drive, the reduction gear, the electric motor, the shaft coupling, the axis, the bearing, the key, the circlip by V installment and roll spare part and so on drive wheel installments,And completes the correlation selection and the corresponding mechanics examination, with realizes two to need the butt weld the marine riser automatically to, and in the synchro completes the further welding after the spot welding.

Key words Water-secluding pipe; auto to zero; “V” model equipment.

前言

隔水管系统也称做水下器具。它是移动式海上钻井装置不可缺少的复杂的器具，它的完善与否直接关系到深海钻井的成败。

应该认为，从海上钻井装置到下列海底井口的全部隔水导管件统称为隔水管系统。通常的隔水管系统的部件有活节联接器、球节、伸缩节、张力器、分流器、运动补偿器、水下防喷设备、水下井口设备、水下井口设备、挠性隔水管和防喷器连接器等。
