Standard Specification for Lap-Joint Type Flange Adapters for Polyethylene Pressure Pipe in Nominal Pipe Sizes <fraction><num>3</num><den>4</den></fraction > in. to 65 in. 标称管道尺寸为3</num><den>4</den></fraction>英寸的聚乙烯压力管用搭接式法兰接头的标准规范 到65英寸
发布日期: 2021-11-01
1.1 本规范涵盖了适用于将聚乙烯管道连接到其他法兰管道和部件(如阀门和法兰管件)的法兰适配器(FA)的聚乙烯材料和尺寸。本标准描述了外径受控聚乙烯(PE)管法兰适配器(FA),直径范围为 3. / 4. 在里面通过65英寸。(12毫米至1600毫米)。法兰适配器可以通过各种方法制造,包括注射成型、压缩成型和从坯料或厚壁聚乙烯管加工。 1.2 法兰接头(FA)是搭接法兰组件的主要部件,几十年来广泛用于低压到高压聚乙烯管道系统,用于所有类型的加压流量(气体和液体)应用。法兰适配器的物理形状由管状颈部组成,该颈部与其轮毂为一体。颈部拟与管道对接或熔接- 线当承受支承环及其适当扭转的螺栓螺柱和螺母的分布载荷时,轮毂表面旨在影响密封。 注1: 带滑动螺栓环的聚乙烯管法兰适配器用于相互栓接或栓接至具有(主要)150级螺栓孔模式的金属法兰,如金属法兰标准ASME B16.5、ASME B16.47和AWWA C207中所示。 1.3 以英寸-磅为单位的数值应视为标准值。括号中给出的值是到国际单位制的数学转换,仅供参考,不被视为标准值。 1.4 垫圈的使用和垫圈的选择通常是法兰适配器组件的一个组成部分。有关HDPE法兰接头的更多信息,请参阅塑料管协会技术说明TN-38。 1.5 本标准并非旨在解决与其使用相关的所有安全问题(如有)。 本标准的用户有责任在使用前制定适当的安全、健康和环境实践,并确定监管限制的适用性。 1.6 本国际标准是根据世界贸易组织技术性贸易壁垒(TBT)委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。
1.1 This specification covers the polyethylene material and dimensions applicable to flange adapters (FAs) used to connect polyethylene pipes to other flanged pipe and components such as valves and flanged fittings. This standard describes outside diameter controlled polyethylene (PE) pipe flange adapters (FAs) in diameters ranging from 3 / 4 in. through 65 in. (12 mm through 1600 mm). The flange adapters may be manufactured by various methods including injection molding, compression molding, and machining from billet or thick-wall polyethylene pipe. 1.2 The flange adapter (FA) is the principal component of the lap-joint flanged assembly widely used for several decades in low-pressure to high-pressure polyethylene pipe systems for all types of pressurized flow (gas and liquid) applications. The flange adapter’s physical shape consists of the pipe-like Neck which is monolithic with its Hub. The Neck is intended to be butt-fused or fusion coupled to the pipe-line; while the Hub face is intended to affect the seal when subjected to the distributed load from the back up ring with its properly torqued bolt-studs and nuts. Note 1: Polyethylene pipe flange adapters with slip on bolt rings are intended for use being bolted to each other or to be bolted to metal flanges having (primarily) Class 150 bolt hole patterns such as those presented in metal flange standards ASME B16.5, ASME B16.47 and AWWA C207. 1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. 1.4 The use of gaskets and gasket selection are often an integral component of the flange adapter assembly. See the Plastic Pipe Institute Technical Note TN-38 for more information regarding HDPE flanged joints. 1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
