Severe Service Access Fitting Assemblies

Cosasco has developed a line of patented internal corrosion monitoring access fittings. By using an insert made of Hastelloy® C276, the seal seat areas and threads are protected from corrosion damage. Hastelloy® C276 is a strong passive film forming material. Consequently, as a cathode in a galvanic cell, it tends to pass very little current. This tendency and the large anode-to-cathode area ratio eliminates galvanic corrosion.

Socketweld Access Fitting Assembly Model 53

The model 53 Socketweld fitting is designed to be socket welded directly to a 2” socket end. Possible configurations include welding to an industry standard “Sockolet” fitting, which is then welded to a pipe or vessel, or welding to a 2” schedule 160 Socketweld “Tee”.
