Integral Pup Joints are straight tubes with union connections on both ends, widely used for transporting high pressure flow in fracturing manifold, cementing manifold, maintenance manifold and test manifold.
Ecostain Integral Pup Joints are forged from premium alloy steel, handled by advanced metal melting and heat treatment technology. Based on the analysis on weight and resistance to erosion,Ecostain has improved wall thickness and inner diameter to extend service life.
Ecostain swivel joints are forged from premium alloy steel, handled with advanced metal melting and heat treatment technology to ensure strength and hardness. Based on analysis of weight, resistance to abrasion and blasting, Ecostain developed optimum wall thickness for swivel joints, introduced advanced equipment and machining technology to ensure the uniformity of wall thickness, the longest service life and highest safety factor with the weight unchanged. Special seal design and seal material significantly increase sealing capability and service life.
