Foreword
This code was revised based on "Standard for Inspection and Evaluation of Thermal Insulating
Work of Industrial Equipment and Pipeline" GB 50185-93 by the China Petroleum & Chemical
Engineering Survey and Design Association and National Administrative Center of Standardization of
Chemical Construction in conjunction with the departments concerned according to the requirements
of "Notice on Printing the Development and Revision Plan of Engineering Construction Standards
and Codes in 2006" issued by the former Ministry of Construction.
During the process of revising this code, the code development team revised, examined and
finalized based this code on extensively soliciting for opinions by wide investigation and study,
earnestly summarizing the practical experiences and making reference to the relevant international
standards and foreign advanced standards.
This code comprises nine chapters and five appendixes, which mainly covers. general provisions,
terms, basic requirement, material, attachment installation, construction quality acceptance of heat
insulating layer, construction quality acceptance of dampproof course, construction quality acceptance
check of protective course, and acceptance of project, etc ..
There have been some significant changes in this code in the following technical aspects.
Provision on term of"inspection lot" was added.
2 Provisions on the quality acceptance of "inspection lot" were added and requirements on the
measured values at the random inspection points of allowable deviation among the inspection lot were
increased.
3 Chapter 4 "material" was added, and the contents on the site sampling and inspection of all
kinds of materials were adjusted appropriately.
4 Chapter of "attachment installation" was added.
5 Provisions on quality acceptance of the heat insulating layers of "embedded layering method",
"smear method", "metallic reflective insulating structure" and "pipe-in-pipe" were added.
6 Section of "protective course made of felt, foil and cloth" was deleted and section of "nonmetallic
protective course" was added .
Provisions printed in bold type in this code are compulsory and must be enforced strictly.
The Ministry of Housing and Urban-Rural Development of the People 's Republic of China is in
charge of the administration of this code and the explanation of the compulsory provisions, the Branch
on Chemical Industry of China Association for Engineering Construction Standardization is in charge
of the current management of this code, and the National Administrative Center of Standardization of
Chemical Construction is responsible for the explanation of specific technical contents . During the
process of implementing th is code, the relevant opinions and advice, whenever necessary, can be
posted or passed on to National Administrative Center of Standardization of Chemical Construction
(Address. Room 1-1-1107, No. 28, Benevolence Hotel, Huai' an East Road, Qiaodong District,
Shijiazhuang City, Hebei Province, 050020, China) for reference during future update.
