JB/T 6013-2000 This standard is a revision of JB/T 6013-1992 "Low-pressure Metal Oil Pipes and Joints for Diesel Engines". This standard specifies the structural type, technical requirements, test methods, inspection rules and marking, packaging, transportation and storage of low-pressure metal oil pipes and joints for diesel engines. This standard applies to diesel engine low-pressure oil pipe components with a cylinder diameter within 200mm. Its basic pressure is 2.5MPa, and its basic diameter is in the range of 3~25mm. This standard was first released as GB 3540~3541-83 in March 1983, and was revised for the first time as JB/T 6013-92 in May 1992.

Foreword
This standard is a revision of JB/T6013-92 "Low-pressure Metal Oil Pipes and Joints for Diesel Engines". During the revision, only editorial changes were made to the original standard, and the main technical content remained unchanged. This standard will replace JB/T
601392
from the date of implementation. This standard is proposed and centralized by the National Internal Combustion Engine Standardization Technical Committee. This standard was drafted by: Shanghai Internal Combustion Engine Research Institute. The main drafters of this standard: Qu Junming and Chen Linshan. This standard was first published in March 1983 and revised for the first time in May 1992. 1Scope
