Designed to protect the thread steel tubing ends and prevent water, dust, corrosive agents, UV rays and other elements to reach the thread area. Our thread protectors are the necessary counterpart of casing, tubing,drill pipe to protect the thread and connection from measurably impacting in transportation and loading and unloading. Our thread protectors are used for casing,tubing,drill pipe with size from 2-3/8 to 13-3/8, round thread, buttress thread and NC, with different colors as required by our clients. Thread protectors used to our casing pipe orders
