Blast Joints are heavy-duty tubular made to protect production tubing. They guard against erosion, abrasion, and wear in fast-moving well environments. Commonly installed across perforated intervals, they provide enhanced wall thickness and surface protection. This helps to extend tubing service life and keep the well safe. Blast joints are widely used in oil and gas production wells where sand, debris, or turbulent flow is present.
