It consists of, at a mi
17、nimum, a risercasing and a riser adapter. These components may be eitherintegrally combined or include provisions for attachment toone another at the point of installation.3.3.3 mechanical fitting, na device for making a connec-tion between piping components that employs physical force todevelop a l
18、eak-tight seal, produce alignment, and provideresistance to pullout caused by axial loads.3.3.4 riser adapter, na type of mechanical fitting used tojoin polyethylene pipe to a metallic piping connection (typi-cally a pipe thread). Riser adapters are sometimes referred to asservice head adapters.3.3.

It may be either rigid, flexible, or acombination of both.3.3.6 qualified installation instructions, na written proce-dure for making a plastic mechanical joint
20、that has beendemonstrated will meet the requirements set forth in the UnitedStates CFR, Title 49, Part 192.283(b), and this standard.4. Materials 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
21、specifications. Specific materials referenced in thissection are common materials used in these types of products.Alternate materials proven 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
22、 either be re-moved or suitably covered with a protective device such as anID plastic sleeve, to preclude any damage to the polyethylenegas piping.4.2 Riser Casings:4.2.1 Rigid riser casings shall be constructed of Specifica-tion A53/A53M or A513 or equivalent metallic materials witha minimum nomina
23、l 0.065 in. (1.65 mm) wall thickness withinthe allowable tolerance ranges of the applicable metallic pipingspecification.4.2.2 Flexible riser casings shall be constructed of plasticcoated flexible metallic tubing providing a crush strength of notless than 1000 lbs. when tested in accordance with UL
