Dorsey To Build

Bulk Resin Containers

For Union Carbide

An order to build 500 seam weld- ed all-aluminum bulk resin con- tainers for the Chemicals and Plas- tics Division of Union Carbide

Corporation, has been awarded to

Dorsey Trailers, Elba, Ala., it was announced by George L. Collier, president. The contract figure was given as in excess of two-million dollars.

Especially designed for hauling resin pellets, the 30-foot by 8-foot by 8-foot boxes will be of exterior post construction to provide smooth interior surfaces. Specifi- cations call for baffles in all cor- ners to prevent trapping bulk ma- terials. Another set of baffles, be- tween two 8-inch diameter dis- charge chutes on one end, facilitate unloading by tilting. Net usable cargo volume will be 1,630 cubic feet.

The roof of each container will have a 20-inch loading hatch and an 8-inch inspection port. All clo- sures will be subjected to air and soap testing to assure water tight- ness to protect cargo from con- tamination.

Union Carbide uses containers extensively in transporting resins from its plants by sea, rail and truck. Dorsey, a subsidiary of The

Dorsey Corporation, will build the containers at its manufacturing facilities in Elba.

Building an LNG tanker?

Which metal is best for your tanks: 9% nickel steel, stainless steel or Invar alloy?

All three nickel alloys are excellent for tanks carrying LNG and other cryogenic liquids. Your choice depends on the de- sign you select for your ship. 9% nickel steel.

The best choice for self-supporting tanks. 9% nickel steel provides a high strength-to-weight ratio and retains excellent toughness and ductility down to — 320°F. Has a low coefficient of expansion and provides excellent weld- ability.

Kvaerner-Moss decided 9% nickel steel and a self-supporting, spherical- tank concept were best for its new 87,600m3 tankers soon to be built in

Norway.

Sell-supporting spherical-design tank utilizing 9% nickel steel.

Type 304 stainless steel.

Used for large-capacity, membrane-type tanks.

Extremely tough and highly ductile at all cryogenic temperatures, Type 304 stainless steel has excellent formability and easy fab- ricability.

One type of stainless steel membrane con- sists of thin sheets corrugated in two direc- tions at right angles.

Gazocean of France selected Type 304 stainless steel and the membrane waffle de- 16 Maritime Reporter/Engineering News
