The direct connection + aerogel design is the latest research result.

The direct connection type full length insulation tubing is a structure in which the inner tube is connected by direct connection. It can greatly reduce the heat loss at the short section. Aerogels have been applied to the thermal insulation pipes of national defense industry, aircraft, metallurgy, chemical industry and other fields. Combined with the characteristics of aerogels, our company has developed a new aerogel thermal insulation oil casing.

The aerogel heat insulation oil casing has the advantages of more stable heat insulation performance and more than 1.5 times of service life compared with the vacuum heat insulation oil casing. The matching use of heat insulation bushing and new type heat insulation coupling can greatly improve the efficiency of the pipe string in the operation process and reduce the casing damage caused by high temperature.
