ETHYLENE PYROLYSIS (cracking) COILS

Duraloy also has a long history of manufacturing high quality ethylene pyrolysis and other process coils. Depending on the application, Duraloy has manufactured coils in alloys such as MO-RE-10MA®, MO-RE-40MA®, Supertherm®, HK-40 and CY-40 alloys. The coils, which are made up of a variety of centrifugal tubes and static castings welded to form a coil, are fully fabricated and tested in our Scottdale, PA facility.

Reformer Tubes

Duraloy reformer tubes are centrifugally cast in Scottdale, PA. These tubes are cast in our high temperature alloys, such as MO-RE 10, TMA 6300 and TMA 6301. Our patented alloy TMA 6301 was developed with Oak Ridge National Laboratory to increase stress-to-rupture properties with no increase in cost. Our proprietary alloys increase the life expectancy of your reformer tubes.

Manifolds

Duraloy has extensive experience in the manufacturing of manifolds, collectors and headers. Duraloy manufactures, assembles and inspects these fabrications in Scottdale, PA from cast and wrought components.

TUBE SHEETS

This tube sheet is to be used in the convection section of a polypropylene furnace. The large flange across the bottom will be drilled with bolt holes and bolted to a structural member on the floor of the furnace then have tubes threaded through the holes and laid across the top of the support. The tube sheet insures that the tubes will maintain even spacing in service allowing the heat from the furnace to circulate evenly around the tubes.

This tube sheet is to be used in the convection section of an ethylene furnace. The large flanges on both sides will be used to secure the casting into the walls of the furnace. The user will then have tubes threaded through the holes and laid across the top of the support. This tube sheet is made in HK-40 alloy.
