The above standards shall be implemented from October 1, 2000. State Administration of Petroleum and Chemical Industry
March 31, 2000
This standard is based on the requirements of the former China National Petroleum Corporation document 198 CNPC Technology Supervision, No. 33 "Notice on the 1998 National Standard Industry Standard Formulation and Revision Project Plan for the Petroleum and Natural Gas Industry", edited by the Engineering Department of Shengli Petroleum Administration Bureau, not The Oil Engineering Technology Research Institute participated in the preparation of this standard. During the preparation of this standard, the members of the preparation team followed the relevant national policies and conducted extensive research. On the basis of summarizing the design and construction experience of cement mortar lining of steel pipelines in oil engineering construction in the past, they used the American Petroleum Institute standard APIRPIOF "Recommended Practice for the Installation, Installation and Connection of Cement Mortar Lining of Steel Pipelines (3rd Edition, September 1994)" in a non-equivalent manner to produce a draft for soliciting opinions. They also widely solicited opinions from relevant natural gas industry design and construction units in various ways, repeatedly revised the main issues, and finally the draft was submitted by the Oil Engineering Construction Professional Standardization Committee. The committee will work with relevant departments to review this standard. It is divided into 8 chapters, with the main contents of general principles, design, construction, safety and environmental protection, quality inspection, repair, installation, transportation and stacking, and delivery documents, etc. In Appendix A of this standard, the amount of cement and sand used in the application of cement mortar lining is calculated.
