A header or other pipe under pressure which is blanked at its terminal end by a closure plate is extended without the need of a shutdown or the construction of bypass piping. In a series of steps in the method disclosed, alternate bolts in the ring of bolts holding the closure plate to the annular flange of the existing pipe are variously repositioned or replaced to accommodate the construction of the extension while maintaining an adequate seal to prevent the escape of the pressurized fluid in the pipe. A structure which is installed as a product of this method and an apparatus used in this installation are also disclosed.

Method for installation of an extended header

A header or other pipe under pressure which is blanked at its terminal end by a closure plate is extended without the need of a shutdown or the construction of bypass piping. In a series of steps in the method disclosed, alternate bolts in the ring of bolts holding the closure plate to the annular flange of the existing pipe are variously repositioned or replaced to accomodate the construction of the extension while maintaining an adequate seal to prevent the escape of the pressurized fluid in the pipe. A structure which is installed as a product of this method and an apparatus used in this installation are also disclosed.

Apparatus for extending a header

A cylindrical drum having a lining spaced apart from the shell of the drum is rotatably mounted on a frame movable on rails along the coke side of a coke oven battery. A fume shield is fixed to the frame and covers openings in the shell and lining through which hot coke passes, when pushed from a coke oven chamber. A hood is fixed to the structure supporting a coke guide and has a movable portion that coacts with the rotatable shell when coke gravitates into the shell. The drum is rotatable to several operative positions.

One-spot cylindrical coke quenching car and quenching method

A generally cylindrical drum of heat stress and corrosion resistant construction, and having an opening therein, is rotatably mounted on a frame movable on rails along the coke side of the coke oven battery. A movable cover is fixed to the shell and covers the opening in the shell through which hot coke passes, when pushed from a coke oven chamber. A hood is fixed to the structure supporting a coke guide and has a movable portion that coacts with the rotatable shell when coke gravitates into the shell. The drum is rotatable to several positions. Means are included to quench the hot coke and to extract the particulate laden steam which is generated by the quenching operation. Additional means are included to remove noxious gases and particulate matter which emanates from the hot coke.

One-spot rotary coke quenching car

Associated with a coke quenching car, preferably a one-spot car, is a coke guide that carries a distributor trough. The distributor trough is pivotably mounted so that when the coke guide is racked out to transfer coke into the quenching car, the distributor is positioned to transfer the coke further out into the car and to better distribute the coke in the car.
