What Is a Hammer Union?
A hammer union is a quick connection fitting for high pressure flowline service. It normally includes a male sub, female sub, wing nut and seal ring. During operation, the crew aligns the two subs and tightens the wing nut with a hammer. Then the rigid ACME thread and sealing structure create a strong pressure connection.
Field crews often need to install, remove and reposition pressure lines during cementing, fracturing, acidizing, well testing, drilling fluid circulation and workover operations. A hammer union gives them a practical way to complete these connections without complex tools. Because of this, Weco type hammer unions remain common parts in pressure pumping packages, treating iron systems, manifold assemblies and temporary flowline layouts.
SGPE hammer unions follow common international oilfield connection practices. English system dimensions help customers match many equivalent products used in the global petroleum market. When the figure number, size, pressure rating and sealing structure match correctly, SGPE seal rings can interchange with SPM or FMC equivalent products.
