United States13.3 Definitions:3.3.1 anodeless riser, na type of mechanical fitting whichis designed to transport gas from underground polyethylenepiping to above-ground
16、 metallic piping. When properlyinstalled, polyethylene pipe is the gas carrier in the belowground portion of an anodeless riser and is protected by ametallic riser casing when it extends above ground level.3.3.2 field-assembled anodeless riser kit, nA kit contain-ing all of the elements required to
17、assemble an anodeless riserat the point of installation with the exception of the gas-carrying polyethylene pipe. It consists of, at a minimum, a risercasing and a riser adapter. These components may be eitherintegrally combined or include provisions for attachment toone another at the point of inst
18、allation.3.3.3 mechanical fitting, na device for making a connec-tion between piping components that employs physical force todevelop a leak-tight seal, produce alignment, and provideresistance to pullout caused by axial loads.3.3.4 riser adapter, na type of mechanical fitting used tojoin polyethyle
19、ne pipe to a metallic piping connection (typi-cally a pipe thread). Riser adapters are sometimes referred to asservice head adapters.3.3.5 riser casing, nthe metallic, non-gas carrying portionof an anodeless riser that serves as a protective conduit for thepolyethylene pipe. It may be either rigid,
20、flexible, or acombination of both.3.3.6 qualified installation instructions, na written proce-dure for making a plastic mechanical joint 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.
21、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 proven to provide equal or be
22、tter 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 polyethylenegas piping.4.2 Riser Casing
23、s:4.2.1 Rigid riser casings shall be constructed of Specifica-tion A53/A53M or A513 or equivalent metallic materials witha minimum nominal 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 cons
24、tructed of plasticcoated flexible metallic tubing providing a crush strength of notless than 1000 lbs. when tested in accordance with UL 360,section 11.1. The flexible tubing shall also be capable ofwithstanding a tensile pull of 300 lbs. force without breaking orunwinding when tested in accordance
25、with UL 360, section10.5.4.3 Moisture Seal:4.3.1 The riser casing shall include a bushing or seal at thepoint where the PE pipe will enter the casing. This seal shallprotect the PE pipe from being damaged by the casing endduring field assembly and resist the entry of moisture into thecasing interior

Separation ofthe casing material from the riser adapter shall constitutefai
31、lure of this test. In designs where the riser casing isconstructed of a minimum of schedule 40 steel pipe and theconnection to the riser adapter is made using a standard ASMEB1.20.1 pipe thread, the design shall be considered to meet therequirements of this section and no testing is required.8.
