Product Description Additional comments Stowage Finished steel products Cold-rolled steel coil Steel forged or rolled into coil and packaged. Weights of this product vary up to a maximum of 40 tons. 1 Cold-rolled steel is a finished product that is unwound for immediate use. Hot and cold rolled steel coil is a product that is stowed at the bottom of the cargo hold with the ‘eye’ pointing in a fore and aft direction. Rows of steel coils should be stowed at least 4 to 6 inches (10 to 15 cm) apart to ensure the sides of coils are not damaged during loading, transit or discharge. Hot rolled steel coil Semi-finished steel forged and rolled into coil. Weights of this product can vary up to a maximum of 40 tons. Hot-rolled steel is normally unwound and processed into cold-rolled steel. American Club: Transport Guidance for Steel Cargoes 31 Steel wire rods (coiled) Long, thin steel rods produced by either hot or cold rolling. Coiled wire rods can be damaged through compression, e.g. due to high stowage or compression against tank top and vessel sides or bulkheads. Coiled steel wire rods are normally stowed in athwartships rows with the axis fore and aft. Coils should be stowed upright so that each coil rests against an adjacent coil. The coils in successive tiers should be stowed so that each coil overlaps the coil below. Steel plate Elongated, thick flat cold rolled steel plate generally of up to 2 inches (5 cm) in thickness. Steel plate is of multipurpose use for a variety of steel based products and structures. Steel plate is usually stowed with the longer axis stowed fore and aft but is sometimes stowed athwartships when bundled. Steel/cast iron pipe (large diameter) Large diameter steel or cast iron pipe whereby ends may be, for example, threaded, beveled, swaged or flanged. The ends of large diameter pipes are prone to damage (e.g. swaged ends). Pipe ends may be shipped with protective coverings or inserts to prevent handling damage. Steel and cast iron pipe should be stowed fore and aft. The shipper/ manufacturers should be consulted as to the maximum allowable tiers for stacking large diameter pipes. Steel pipe (small diameter) Finished steel product. Ends may be beveled, swaged or flanged and may have protective covering. Small diameter pipes in single unit or bundled in groups. Ends of pipes are susceptible to damage. Small diameter steel pipe is usually packed in bundles and should be stowed in a fore and aft direction. Steel piling and column Long, finished cold rolled molded steel sheet products. Primarily used for construction purposes. Steel pilings and column are usually packed in bundles and should be stowed in a fore and aft direction. 1 A ton is a unit of measurement equaling 2,000 pounds. In non-U.S. measurements, a ton equals 2,240 pounds. A tonne, also known as a metric ton, is a unit of mass equaling 1,000 kilograms. tải về 1.97 Mb. Chia sẻ với bạn bè của bạn:
