Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009.

This standard is the revision of CJ/T 163-2002 "diversion type positive displacement water heaters and semi-positive displacement water heaters (U-tube bundle)", this Compared with CJ/T 163-2002, the main technical changes are as follows.

--- Updated "reference standard" version;

--- Complement the "check hole" standard;

--- Supplemented the smooth U-shaped, nodal U-tube bundle definition;

--- Complement the smooth tube, knot tube diversion type volumetric water heater definition;

--- Supplemented the smooth tube, knot tube semi-volume water heater definition;

--- Complement the knuckle surface U-tube water heater model mark;

--- Complement the knot surface U-tube water heater corresponding thermal parameters;

--- Remove the U-shaped heat transfer tubes with seamless steel pipe provisions;

--- Unified shell-side, the pressure of the design process;

--- Complement the semi-volume water heaters manhole settings and manufacturing requirements;

--- Complement the knot section U-tube bundle structure and processing requirements.
