What is Corrugated Metal?

Corrugated metal hose (English name Corrugated metal hose) is one of a series of metal hose products. Corrugated metal hose (hose for short) is a high-quality flexible pipe in modern industrial pipelines. It has good softness, resistance Fatigue and high pressure, good temperature resistance, corrosion resistance, strong sealing and many other characteristics, much longer life than other hoses (rubber hose, plastic hose). It is widely used in aviation, aerospace, petroleum, chemical, steel, electric power, papermaking, construction, rubber, textile printing and dyeing, medicine, food, transportation and other industries. With the development of modern industry, the demand for high-quality, high-performance corrugated metal hoses will increase.

Corrugated metal hose

Definition For ring-shaped or spiral corrugated pipes with a slenderness ratio greater than or equal to 3 for outer armored metal wires or machine-made woven nets, they are called metal hoses. In European and American countries, it is customary to call its flexible tube (Corrugated Hose) or flexible hose (Corrugated metal hose).

Application of corrugated metal hose

In China's metal hose industry, the main applications of domestic metal hose products are as follows: the product structure is single, the equipment is simple, and the quality is unstable.

1. Military hose industry

The military stainless steel metal hose market is divided into two categories: skycraft hoses and ground equipment metal hoses. Due to the constraints of the shaped products, the stainless steel metal hoses for the sky have not been replaced by new products, and they are still mainly seamless hoses. Military equipment hoses for ground equipment have a tendency to be replaced by civilian stainless steel metal hoses due to the low risk of use. The structure of the two hoses is not much adjusted.

2.Main industries of civil hoses

(1) In the steel and metallurgy industry, stainless steel metal hoses are gradually transitioning from product performance competition to performance-price ratio competition, and the product structure is basically finalized. The application of stainless steel metal hoses in this industry has been widely recognized.

(2) The situation in the petrochemical industry is relatively complicated. On the one hand, the market demand for large-diameter high-pressure hoses and central drainage hoses for storage tanks is growing, and domestic new product development in this field is far from being in place. On the other hand, there are some products that have been replaced by hoses in some occasions, such as non-metallic pipes (light weight and suitable pressure resistance) appearing in the market of pipelines for terminals. As the petrochemical industry is currently a large market for domestic hoses, each company is fiercely competitive in this field, and new product development costs invested in this field are also large.

3.Special hose industry

This industry mainly refers to the marine hose series. Due to its high equipment requirements and huge investment scale (about 500 million yuan), China currently does not have the ability to develop and develop it on its own, mostly relying on imports, although the market is huge.
