An automatic device for metal hose welding was designed based on the common latitudinal seam welder,according to the structure of high-pressure metal hose.

This paper describes the application of the safety systems engineering method to solve the pipeline stress of the tanks' exit and entrance and the application of metal hose on the tank of the No.

materlal and paraineter of metal hose,the performance of the metal hose was improved,it meeted the requirement of connecting lance in Pangang converter.

In order to simulate the acceleration pulse in impact tests, the design method of the acceleration pulse generator by the multi-segment tubes with different thicknesses based on the theory of metal tubes press expansion was researched.

There had existed corrosion and leakage problems for the flexible metal tubes at the satellite platforms in Chengdao Oilfield for many years.

Improving the flexible metal tube used in the system of supply and return steam line for hot press,that is to avoid the leak of the steam,and then to raise the product quality and increase the production profits.

The stator of the motor composes of a metal tube with twelve arrises and PZT pieces stuck to the metal tube.

Corrosion of underground metal tubes and reinforcing steel bars in the building not only resultin heavy economic losses,but also bring out environmental pollution,and give rise to hidden accident.

The dissertation choosed thefuze inductive setting as the research object, especially the study of metal tube, and bringforward some solving ways.

The preparation of metal micro-tubes via electroless plating using spider silk as templates was investigated.
