J8/J8/J8/J8/j9/4/4 blocks are mainly used to transport low-temperature media pipes. If special materials are not used for protection outside, 13785583922 of the cold data will be lost during the transportation, the transportation fails, so the low-temperature transmission pipeline should use special materials for cold storage. Generally, 13785583922 of the cold storage pipe is wrapped in pine block, and the support Pipe tray of the cold storage
