API Std 650 open-top tanks envelope seals

Considering the large workload of allocation and transportion for our steel materials, we have built special shipping department, and make it independent form transportation department. The transportation department is in charge of transporting steel materials from our mill and warehouse to the port, and our shipping department is in charge of the shipping matters. So that our whole shipping efficiency is improved, and shorten time for customers to receive goods.

The lip seal of floating roof storage tank, API Std 650 open-top tanks relies on the sliding contact between elastic lip and tank wall. This kind of seal has strong applicability, but the requirements of manufacturing technology and material selection are high, and the determination of elastic seal also exists. The secondary seal of floating roof storage tank, API Std 650 open-top tanks is to add a seal on the basis of primary seal. It is proved by experiments that the secondary seal can reduce the liquid consumption by more than 50%, and has a more significant effect in safety.
