High-pressure metal hose and preparation method thereof

Abstract

The invention discloses a high-pressure metal hose and a preparation method thereof. The metal hose comprises a net-body part and connectors arranged at two ends of the net-body part, wherein the net-body parts comprises a metal corrugated pipe, a connecting pipe, a ring and a steel wire net sleeve; and the metal corrugated pipe is prepared from the following components in parts by weight: 21-39 parts of iron, 12-25 parts of nickel, 11-22 parts of chromium, 4-11 parts of tin bronze, 5-11 parts of titanium, 3-8 parts of silicon nitride, 1-5 parts of aluminum oxide and 1-4 parts of tin oxide. The metal hose disclosed by the invention has the following advantages: (1) the high-pressure-resistance performance is excellent, and the water attack and the pressure of a conveying medium can be effectively resisted; and (2) through addition of a reasonable amount of carbon, the own anti-corrosion performance of the metal hose is improved, and the possibility of fatigue failure of the metal hose is lowered.

Description

technical field

[0001] The invention belongs to the field of metal materials, and relates to a metal connecting pipe, in particular to a high-pressure-resistant metal hose and a preparation method thereof. Background technique

[0002] The metal hose is a pipe fitting that transports various fluids with bellows as the core component. Its main function is shock absorption and noise elimination. It has good flexibility, light weight, corrosion resistance, fatigue resistance, high and low temperature resistance, shock absorption and noise reduction. , strong sealing, long service life and other advantages, widely used in aerospace, locomotive ships, metallurgy and petrochemical, urban water supply, medical and health, textile electronics, energy construction and other fields. In recent years, the market demand for high-end metal hose products has grown at a rate of more than 50% per year, and imported metal hose products have also increased at a rate of 30% per year. Therefore,...
