The PARVEEN Forged Knuckle Joint, when made up in a string of wireline tools, provide strong flexible joint to permit angular movement of the string in a deviated hole. The Forged Knuckle Joint consists of only two parts – a pin section and a box section. The socket of the pin section is formed around the ball of the box section to form an integral unit. If desired, a hole can be drilled lengthwise in the knuckle joint to permit passage of conductors. A 40,000 lb pull test load is applied on each knuckle joint, to ensure integrity of the ball joint connection under repeated usage.
