Certified Cast Steel Thread Protector Certified Cast Steel Thread Protectors (CCSTP) with lifting bails offer the ultimate in thread protection, including certified lifting capacities to ensure safe handling of tubular products during manufacture, shipping or at the rig site. The CCSTP is manufactured from steel castings with heavy-duty bails suitable for picking up and laying down a drill collar with the catline. Each lifting bail is proof tested to 300 percent of the maximum anticipated load and is capable of picking up one drill collar within the recommended diameter for the type and size of connection on the CCSTP. Threads and shoulders are precision machined. Features and Benefits:
Each CCSTP has been load tested and inspected prior to sale. Due to the rough nature in which drill collars are handled, Smith Services recommends frequent inspection to ensure the bail is not cracked and that proper make-up to the connection is possible. Note: Cast Steel Thread Protectors should only be used to pick up or lay down one drill collar at a time. http://www.siismithservices.com/b_products/product_page.asp?ID=590
