Information

RIGID VACUUM INSULATED PIPE

Each section of rigid VIP is constructed of a rigid inner and outer pipe. Generally, there are three connection types between pipes. When VIP need be connected to equipment, storage tank and so on, the connection joint can be customized according to customer requirements.
