Swivel Joints are used in flow line. These products are made from high strength alloy steel by forging and the heat treatment is carried out on it, thus its long service life and service strength are guaranteed under the rated working pressure. They are designed for the critical service conditions that exist in fracturing, cementing, acidizing and well testing. Both ends of the swivel joint can be connected by the LP inner thread connection and also can be connected by union so they could be installed in various kinds of pipelines.
