More Information
Summary:An apparatus for marking a piping tube of a semiconductor manufacture line is provided to conveniently indicate an inserted length of a tube being inserted into at a connection section of the piping tube by using a pen holder. A body(10) is provided with a fitting hole(11) into which a piping tube is inserted with a certain depth from an upper surface. A shaft is rotatably inserted in a pen holder(20) with a certain depth from one side of the fitting hole to the upper surface of the body. A marking pen(40) horizontally passes through the pen holder and then is inserting-fixed into a head of an upper section of the pen holder. The fitting hole is numerously formed on the body with different diameters. A check hole for visibly checking a lower section of the fitting hole is horizontally formed on an outer circumference of the body.
