The mechanical steel tubing produced at Hannibal Tubular Products conforms to ASTM A-513 specifications. Tolerance for size, straightness, twist, wall thickness, and length are in accordance with those published by the American Society for Testing and Materials (ASTM).

Flash-in tubing is standard and the most commonly requested. If close inside diameter tolerances are required, then Hannibal also has the ability to flash-remove or flash-roll as required by the customer.
