GB/T 21435-2008Phase change heater (English PDF)

Foreword

Appendix A of this standard is an informative annex, Annex B normative appendix.

The standard proposed by the Ningxia Hui Autonomous Region Quality and Technical Supervision.

Introduction

Although China's oil and gas industry has been a complete furnace standard system, but due to the phase change furnace works and manufacturing, Installation, use requirements, both with the traditional pressure or atmospheric heating furnace a clear distinction between the existing furnace technical standards and regulations, norms imperfect fit Phase change furnace.

The standard in a practical and feasible principle, phase change furnace design and manufacture the technical requirements. Given there is no phase change heat Practice safe use of oven management, the special circumstances of the specification, installation and maintenance of the standard from the perspective of the phase change of the furnace operation and management of mention A basic requirement.

This standard specifies the minimum security requirements change furnace, furnace for phase change performance and environmental performance raised the basic requirements.

1 Scope

This standard specifies the phase change furnace terminology, definitions, parameters, series and model preparation methods, as well as the design, manufacture, testing, inspection, security Full terms of the basic requirements for secure attachment and performance.

This standard applies to the manner of phase change heat the oil industry with indirect heating furnace, namely vacuum phase transition furnace, furnace micro-pressure phase transition And the phase transition pressure furnace, hereinafter referred to as the furnace.
