7-Inch Buttress Plastic Thread Protector — Casing Connection Fit
Description
This 7-inch buttress plastic thread protector enquiry concerns coverage of the selected casing connection during transportation and storage. Provide the full connection designation and pin or box end with the drawing so engagement and clearances can be reviewed.
The 7-inch size label does not define every mating dimension. Confirm the thread geometry, required engagement and end-face clearance against the actual casing connection before approving a protector sample.
Plastic and metal-plastic composite protectors have separate constructions. Specify the plastic resin grade and cap geometry for this item; steel reinforcement requires a separate construction specification.
Inspect protectors for cracked walls, thread damage, distortion and contamination before reuse. Follow the agreed handling and storage procedure for the actual resin and protector design.
Choose the protector by connection fit, thread coverage and handling requirements. Price comparisons do not establish equivalent protection or interchangeability between different constructions.
The featured size is 7 inches with a buttress connection to be confirmed by drawing. Other size and connection references, including STC, LTC, NC and REG, are separate enquiries and are not interchangeable options for this protector. Specify the exact 7-inch connection and pin/box configuration.
