GB/T 34019-2017Ultra-high pressure vessels (English PDF)

Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009.

Introduction

This standard is the National Boiler and Pressure Vessel Standardization Technical Committee (hereinafter referred to as "Commission") is responsible for the development and centralized pressure vessel technology One of the technical standards to regulate the technical requirements for the design, manufacture, inspection and acceptance of EHV vessels built or used in China.

The technical terms of this standard include the procedures to be followed in the construction of UHV containers (ie design, manufacture, inspection and acceptance) begging. As this standard is not necessary, it is impossible to cover all the technical details of the construction of ultra-high pressure vessels in the scope of application. Therefore, Regulations under the premise of the basic safety requirements, should not be banned in this standard does not specifically mentioned the technical content. This standard can not be used as The technical manuals for the construction of UHP containers can not replace the training, engineering experience and project evaluation.

Any ambiguity and consequent misconceptions arising from the publicity or interpretation of the standard by other agencies without the written authorization or approval of the Commission The Commission will not be responsible for any consequences.

Inquiries regarding standard technical terms should be submitted in writing to the Commission Secretariat and be obliged to provide such information as may be required. versus Questions that are not directly related to, or can not be understood by, standard clauses will be considered as technical advice and the committee reserves the right to refuse an answer. See attached Record A.

1 Scope

1.1 This standard specifies the non-welded single-layer ultra-high pressure vessel (hereinafter referred to as container) material, design, manufacture, inspection and acceptance of Claim.

1.2 This standard applies to containers that meet the following conditions at the same time.
