A hammer-lug union is assembled from a male and female component which are welded to pipework. The male and female components are fastened together with a threaded wing nut. The nut has three lugs which are designed to allow tightening with a hammer.
The design of the union allows for quick assembly and dis-assembly of pipework, which is often necessary for mobile rigs in harsh environments.
RBV Energy supply hammer-lug unions for a range of sizes and applications.
