Foreword

GB/T 26978 "on-site assembly of vertical cylindrical flat steel LNG storage tank design and construction" is divided into the following five sections.

--- Part 1. General;

--- Part 2. metal member;

--- Part 3. Concrete components;

--- Part 4. heat insulating member;

--- Part 5. Testing, drying, replacement and cooling.

This section GB/T 26978-2011 Part 3.

This section drafted in accordance with GB/T 1.1-2009 given rules.

The partial modification using EN14620-3:2006 "on-site assembly of steel vertical cylindrical flat operating temperature is between 0 °C ~ -165 °C of Refrigerated liquefied gas storage tank design and construction - Part 3. Concrete components "(in English).

The main differences are as follows.

Retains the LNG-related content, delete and LPG, ethylene, ethane and similar hydrocarbons and liquid ammonia, liquid Oxygen, liquid nitrogen and liquid argon storage and other related content.

Added "Appendix NA (informative), which gives a list of the technical differences and the reasons for reference.
