警告-买方有责任指定产品规格等级（PSL）， 耐腐蚀合金（CRA）组、类别、等级、交付条件和除本文规定的要求外的任何其他要求，以确保产品适用于预期的使用环境。在对含H2S的环境制定具体要求时，应考虑ISO 15156系列；见附录G。应考虑可能导致氢脆的其他变量。除含H2S的环境外，还有其他氢源，ISO 15156系列并未涉及这些环境。本文件规定了耐腐蚀无缝合金的交货技术条件 套管、油管、联轴节库存和附件材料（包括联轴节库存）用管状产品 两种产品规格等级的配件材料: -PSL-1是本文件的基础；-PSL-2，它为既耐腐蚀又耐腐蚀的产品提供了附加要求 以及附录G和附录B中规定的环境和鉴定方法的抗裂性 ISO 15156系列。 根据制造商的选择，可以提供PSL-2产品代替PSL-1。购买本文件时可获得的所有当前修订均包含在购买本文件中。

WARNING — It is the purchaser's responsibility to specify the product specification level (PSL), corrosion-resistant alloy (CRA) group, category, grade, delivery conditions and any other requirement in addition to those specified herewith to ensure that the product is adequate for the intended service environment. The ISO 15156 series should be considered when making specific requirements for H2S-containing environment; see Annex G. Other variables which can contribute to hydrogen embrittlement should be considered. There are other sources of hydrogen besides H2S containing environments, which are not addressed by the ISO 15156 series.This document specifies the technical delivery conditions for corrosion-resistant alloy seamless tubular products for casing, tubing, coupling stock and accessory material (including coupling stock and accessory material from bar) for two product specification levels: — PSL-1, which is the basis of this document;— PSL-2, which provides additional requirements for a product that is intended to be both corrosion and cracking resistant for the environments and qualification method specified in Annex G and in the ISO 15156 series. At the option of the manufacturer, PSL-2 products can be provided in lieu of PSL-1.All current amendments available at time of purchase are included with the purchase of this document.
