Grade 70 Chain

Multi buoy mooring system
Multi buoy mooring system (MBM), a facility of traditional buoy mooring systems, through which ships are typically moored by a combination of anchor and stern mooring buoys, and fixed to a fixed heading. Also known as conventional buoy mooring.
Single point mooring system
Single Point Mooring (SPM) is a facility that fixes a ship to a single buoy or structure through the bow and swings freely with prevailing winds and currents. Three types of single point mooring systems are commonly used: catenary anchor leg mooring, single anchor leg mooring, and turret mooring.
Single Point Mooring (SPM) is a type of floating buoy/dock anchored at sea, allowing for the loading and unloading of liquid cargo such as ships' petroleum products. SPM is mainly used in areas without dedicated facilities for loading and unloading liquid cargo. These single point mooring (SPM) facilities are located a few kilometers away from coastal facilities, connected through submarine and subsea oil pipelines, and can even handle ultra large capacity ships such as VLCC.
Single point mooring (SPM) serves as a connection between onshore facilities and ships, used for loading or unloading liquid and gas cargo.
Some of the main benefits of using SPM are:
*Handling ultra large vessels.
*No need for ships to arrive at the port, saving fuel and time.
*Ships with high draft can be easily moored.
*High quality goods are easy to handle.

Grade 70 chain, also known as grade 70 transport chain, is manufactured in heat-treated carbon steel. The grade 70 chain is an improvement over high test chain and meets stringent Department of Transportation (DOT) regulations. Load ratings of grade 70 chain are approximately 20% higher than grade 43. Grade 70 chain is most popular in the cargo industry as trailer tie downs,

Grade 70 Chain
 
Grade 70 chain, also known as grade 70 transport chain, is manufactured in heat-treated carbon steel. The grade 70 chain is an improvement over high test chain and meets stringent Department of Transportation (DOT) regulations. Load ratings of grade 70 chain are approximately 20% higher than grade 43. Grade 70 chain is most popular in the cargo industry as trailer tie downs, but it’s also used for logging, towing, and other jobs. It is noteworthy that the grade 70 chain should never be used for overhead lifting. The grade 70 transport chain generally features a gold chromate finish, which makes it easily identifiable. Besides, it is usually embossed with 7, 70, or 700.
 
In addition to standard chain, we are able to provide non-standard chains. Please call our sales team at +86-23-67868920 or send email to let us know what are you looking for, we’ll be happy to help.
