Such bends must meet the design requirements of 102.4.5 and 104.2.1 of ASME B31.1 (incorporated by reference; see § 56.01-2). This does not prohibit the use of bends designed as creased or corrugated. If doubt exists as to the wall thickness being adequate, Class I piping having diameters exceeding 4 inches must be nondestructively examined by the use of ultrasonics or other acceptable method. The nondestructive method must be employed where the design temperature exceeds 750 °F.","path":["Title 46—Shipping","CHAPTER I—COAST GUARD, DEPARTMENT OF HOMELAND SECURITY","SUBCHAPTER F—MARINE ENGINEERING","PART 56—PIPING SYSTEMS AND APPURTENANCES","Subpart 56.80—Bending and Forming"],"source_url":"https://www.ecfr.gov/api/versioner/v1/full/2026-08-25/title-46.xml","current_through":"2026-08-25","vintage":"","retrieved_at":"2026-08-27T02:26:22Z","sha256":"2d43d73ea2381501e0d7ec057636c31d04eb484b73f09197c5560371fea10e6f","source_id":"us-cfr","stale":true,"prev":"us/46-cfr-56.75-30","next":"us/46-cfr-56.80-10"},"notice":"GroundRules: Original legal text.
