摘要

"Double sealing system in a composite ascending column that has a set of metal coating method to prevent leakage of internal fluid Pope to the outside of the column, and,Metal composite interface of a composite ascending column ".The present invention discloses sealing systems for composite columns are upward redundant sets of metal coatings and methods of preventing leakage of fluid inside the LaThe outside of the ascending column composite.An elastomeric seal is formed between a tip provided at the end of an elastomeric interface metal composite (MCI) of the set of coating and a layer of elastomeric shear pro.Life on the set of coating.The elastomeric seal and a mechanical seal between the MCI and a transition ring that holds the coating on the MCI provide a dual sealing system for the composite to prevent ascending columnThe inner fluid leakage.In the case of the integrity of the mechanical seal or the integrity of the coating to be compromised, the elastomeric seal prevents fluid leakage to the outside of the ascending column composite.
