Ma
20、terials and Manufacture4.1 General:4.1.1 All materials of the riser kit shall meet the perfor-mance requirements of this specification and applicable refer-enced specifications. Specific materials referenced in thissection are common materials used in these types of products.Alternate materials prov
21、en to provide equal or better perfor-mance shall be acceptable.4.1.2 All burrs on metal components which could damagethe polyethylene piping during assembly shall either be re-moved or suitably covered with a protective device such as anID plastic sleeve, to preclude any damage to the polyethylenega
22、s piping.4.2 Riser Casings:4.2.1 Rigid riser casings shall be constructed of Specifica-tion A 53 or A 513 or equivalent metallic materials with aminimum nominal 0.065 in. (1.65 mm) wall thickness withinthe allowable tolerance ranges of the applicable metallic pipingspecification.4.2.2 Flexible riser
