TSO8277:1988 "Shipbuilding Pipework Information Transfer" specifies the information, which is an important technical basis standard for computer-aided piping production design and manufacturing. Computer-aided design and manufacturing of ship piping has been widely adopted in my country's shipbuilding industry. Therefore, this standard is formulated on the basis of equivalent adoption of ISO8277:1988. It will play a positive role in unifying the technical language of computer-aided design and manufacturing of ship piping in my country's shipbuilding industry and strengthening scientific and technological exchanges at home and abroad. This standard is proposed by China Shipbuilding Industry Corporation. This standard is sponsored by the Comprehensive Technical and Economic Research Institute of China Shipbuilding Industry Corporation. The drafting unit of this standard is: China Shipbuilding Industry Corporation No. 10 Research Institute. This standard is mainly composed of: Chen Ether Group.

ISO Foreword
ISO (International Organization for Standardization) is an international organization composed of international standard organizations (ISO member bodies). The formulation of international standards is carried out by ISO technical committees. Each member group has the right to participate in this committee if it is interested in the subject of a technical committee. International organizations with governmental and non-governmental relations with ISO may also participate in this work. The draft international standards adopted by the technical committees shall be sent to the member bodies for approval before being approved as international standards by the ISO Council. According to the ISO standard formulation procedure, the draft national standard shall become an international standard only if at least 5% of the member bodies vote in favor. The international standard ISO 8277 was formulated by ISO/TC:8 Technical Committee on Shipbuilding and Superstructures. Users should note that all international standards are subject to frequent review and revision. Unless otherwise specified, other international standards referenced in this standard refer to the latest versions.

Shipping Piping System Information Transfer
Eqv1s8277:1988
This standard specifies the minimum data required to be transferred from the technical department to the production department during the pre-processing and assembly of the piping system in the shipbuilding industry.
This standard does not include the data generation, presentation method and file composition. 2 Pipeline system information
There are three types of piping system information that need to be transferred from design to manufacturing, namely: standard parts information, non-standard parts information and management information, see Table 1.
