Carbon Steel A105 Gr B Shoulder Plugs for Heat Exchanger
Carbon Steel A105 Gr B Shoulder plugs are made for plug type header boxes in air cooled heat exchangers or fin fan air coolers. A shoulder plug and gasket are located opposite each tube which allows access for inspection and cleaning of individual tubes. Spare plugs and gaskets may be needed to replace originals during routine maintenance or used to plug leaking tubes.
Carbon Steel A105 Gr B Shoulder Plugs are installed in upstream offshore/onshore oil production and initial processing installations.
