III. Transmission Pipeline of Cryogenic Liquid

DN150 Cryogenic Rigid Pipe

DN50 Cryogenic Flexible Pipe

Overview:

Cryogenic liquid transmission pipeline of high vacuum multi-layer insulation manufactured by

our company has unique technology, advanced craft, excellent function, low evaporation loss

rate, aesthetic modeling and convenient installation. Its shell is polished, aesthetic and practical.

It is also used in many industries and areas.

Production Materials:

Inner and outer tubes are made of 0Cr18Ni9 seamless stainless steel.

Product Feature:

Structural innovation: automatic centering rigid support is used for inner and outer tubes so that

cold loss brought about by short circuit of inner and outer tubes due to pipe deflection or

unreasonable support is prevented.

Excellent insulation: between pipe sections are seamless corrugated compensator structures.

Interlayer is made of insulation materials of high reflectivity and excellent insulation

performance.

Long service life: outer tube has adjustable vacuum valve so that degree of sealed vacuum is

high. The vacuum can also be pumped repeatedly. However, some defects like low vacuum

degree, short service life and high evaporation loss in “one-off vacuum” of traditional product

are removed.

High safe reliability: adjustable vacuum valve can fasten or loosen itself. It can also

decompress itself when overpressure brought about by damaged vacuum interlayer occurs.

High technological content: an optional special vacuum pressure sensor for measuring

vacuum is offered if there is a need from user.

IV. Cryogenic Electronic Product

4.1 Monitoring Management System for Liquid Nitrogen Biological Container

Monitoring management system for liquid nitrogen biological container is a system

integration product that was studied and developed for five years by our company with

creatively advanced data collection technology, communication technology, automatic control

technology, and embedded software technology.

The system is mainly made up of remote terminal unit (RTU) of intelligent monitoring of

biological container and data service center (DSC). Intelligent monitoring terminal unit has the

following functions: real-time collection of temperature of low and high position; real-time

monitoring of liquid height; calculation of liquid nitrogen loss; automatic switch of liquid inlet

electromagnetic valve according to liquid level and temperature; internal local area network is

used to connect tank body computer with server of monitoring center; DTU sends warning

message to the cell phone of watch keeper including low-and-high-position overheating

warning and sensor failure warning; powerful MIS management system for objects in

cryopreservation; and so on

Data monitoring center analyzes and stores data provided by RTU and these data are

investigated by management staff. Monitoring terminal unit can check conveniently the state of

every network monitoring terminal by connection of local area network and monitoring center

on a computer in the monitoring center without reaching any biological storage container.

Monitoring center computer is also in charge of storing and managing all objects stored or to be

stored in the liquid nitrogen tank. Monitoring center software is mainly made up of eight major

modules including operation model selection, data monitoring, alarming, and object

information management.
