Expansion joints Di pipe external protection and bred through the treatment to obtain a spherical graphite cast iron effectively improve the mechanical properties, in particular to improve the ductility and toughness, but also to obtain high strength than carbon steel.
Expansion joints to check before the installation of its type, size and piping configuration must meet the design requirements.
The expansion joints of the band should be noted that the inner sleeve of the Di Pipe Standard Lining and Coating to a direction consistent with the medium flow direction, a hinge-type hinge expansion joints and displacement plane of rotation of the rotational plane should be the same.
