Abstract: The invention consists of a cylindrical hollow stuffing box (1) for accommodating geometrical differences between rotating, passing drill pipes (B) and pipe connectors (B' ') the diameter of which exceeds that of the drill pipe. The stuffing box (1) consists of an outer housing (2), an upper ceramic disc (3) with an upper set of sipes (4), a lower ceramic disc (5) with a lower set of sipes (6), an outer packer (7) and an inner packer (8) surrounded by an annulus (9). The inner packer (8) seals against the drill pipe (B) such that the packer (8) during operation rotates together with the passing drill pipe (B). The discs (3,5) are fastened to top and bottom of the housing (2) and have an opening, the diameter of which exceeds the diameter of the pipe connectors (B' '). The packer unit with the integrated sipes (4,6) will also be rotated by the drill string during operation, as the sipes (4,6) abut the discs (3,5). When the pipe connector (B' ') is to pass down through the stuffing box (1), then firstly the upper sipes (4) and then the packer (8) will be forced out into the annulus (9), and as soon as the pipe connector (B' ') has passed the upper sipes (4) these will be forced back by the pressure in the annulus (9) whereafter the lower sipes (6) are correspondingly activated.

Abstract: The invention relates to a method for production of a cylindrical acid proof, seamless pressure vessel having hemispherical top and bottom by powder moulding in an HIP (Hot Isostatic Pressing) process. Sheet metal moulds are produced constituting an internal shell (1), lower part of an external shell (3), upper part of an external shell (4) with filling spout (5) with corresponding top and bottom. Distance pins (2) decide the wall thickness and are mounted outward from the internal shell which is led down into the lower part of external shell (3) whereafter shell part (4) with filling spout (5) closes the volume be-tween the internal and external shells which is then filled with powder through the filling spout (5). The pressure vessel is placed in an HIP-process container for vacuuming, sealing, supply of high-pressure inert gas such as argon, at high temperature such as 1000 °C, for processing together with the distance pins (2) to a compact and homogenous material.

Abstract: The invention relates to a method of using new flushing ports (IA7 IB) when cleaning a piston accumulator (7). Dirty hydraulic oil is returned out via the main port (2) and a return passage (9) until a cleanness grade has been reached. Clean hydraulic oil is forced into the piston accumulator (7) via the axial bores (3A, B) of the flushing ports (IA, B) and further in sloping bores (3C, D), bringing the hydraulic oil into the volume (8) in an upward, tangential direction below the piston (5), into a flushing circulation. By reducing the gas pressure on the gas side (4) of the piston (5) in relation to flushing pressure input from a valve (6), a volume (8) is created on the oil side between the piston (5) and the end bottom (3). The return passage (9) is closed and the piston (5) is brought into its upper position, so that an internal cylinder wall (10) is cleaned. Upon pressure build-up, the return passage (9) is opened, and the piston (5) returns to its end position on the oil side while the supply of clean hydraulic oil is maintained, and the operation is repeated until a cleanness grade has been achieved.
