Aimed at some problems in management of steel bottle of liquefied petroleum gas,based on the technology of the wireless signal communication,a full solution,the comprehensive administrative system of steel bottle of liquefied gas based on Mobitex technology,is proposed.

This paper introduces the design goal of the permanent identificatio n and informatization management system for liquefied gas cylinder, discusses th e feasibility and operability of this system, analyses its compatibility extensi on and security, and puts forward the topological structure of informatization m anagement system network for liquefied gas cylinder.

Technical discussion on periodic survey and evaluation of LPG cylinders;

The burn technique testing in LPG cylinder inspection was simply introduced,The economical benefit was analyzed,and the structure and type of burn furnace was disussed.

The reasons for excessive filling and yield expansion deformation of liquid-phase LPG cylinder which may occur in operation of centralized gas supply are analyzed, and the improvement suggestions are put forward.
