SIGHT GLASS STRUCTURE ON THE PIPE

摘要

PURPOSE: A sight glass structure formed in a pipe is provided to facilitate the handling of a sight glass, since a small sight glass can be always installed despite the large diameter of a pipe. CONSTITUTION: A sight glass structure formed in a pipe comprises a through-hole(31), a connection pipe(40), and a sight glass assembly(50). The through-hole is formed on one side of a pipe. The connection pipe is extended to connect to the through-hole. The sight glass assembly is combined with the end of the connection pipe. The operator can confirm the inside of the pipe through the sight glass assembly.
