[Qinghai Wulan County Qinghua Group] Mining Metal Hose Case Study

Shanghai Songjiang Vibration Absorber Co.,Ltd.’s official website presents: [Qinghai Wulan County Qinghua Group] Mining Metal Hose Information. Songjiang Group manufactures various types of mining metal hose products. Below is a detailed introduction to the mining metal hose used by Qinghai Wulan County Qinghua Group.

1. Introduction to Qinghai Wulan County Qinghua Group:

Qinghai Qinghua Coal Chemical Co., Ltd. is located in Chahanuo, Wulan County, Haixi Prefecture, covering a total area of 259 hectares, with a total investment of about 2.5 billion yuan. The Phase I project of 1 million tons/year coal coking project in Wulan is a landmark project in the Qaidam Circular Economy Pilot Zone. It achieved the construction miracle of starting and completing construction in the same year in high-altitude areas, becoming the world’s highest-altitude, domestically leading, and environmentally advanced coal chemical enterprise.

Qinghai Qinghua Coal Chemical Co., Ltd. recycles and utilizes by-products such as coal tar, ammonium sulfate, and crude benzene, achieving resource recycling and factory-cycle production. The entire industrial park adopts closed-loop water circulation and zero discharge. The Wulan Coal Chemical Circular Economy Industrial Park has now completed the 3 million tons/year clean coal washing plant project, administrative and living facilities in the park, and railway special line projects. The clean coal washing plant project has filled the gap of Qinghai Province’s lack of large-scale modern heavy coal washing plants. The Phase II project of 1.1 million tons/year coal coking and 5×15 MW coke oven gas cogeneration project is under construction.

2. Introduction to Qinghai Wulan County Qinghua Group Mining Metal Hose:

Name: General Metal Hose

Definition: The general metal hose is one of the products in the bellows series and is an important connecting component in engineering technology. It is composed of a bellows flexible tube, wire braiding, and fittings. Its main characteristics are easy installation, versatility, and good sealing.

Applications:

The general metal hose is used as a compensating element, sealing element, connecting element, and damping element in various gas and liquid pipeline systems, as well as length, temperature, position, and angle compensation systems. It is widely used in aerospace, petrochemical, mining electronics, mechanical shipbuilding, medical health, light textile electronics, energy construction, and other fields.

3.Installation and Use Precautions:

1. Standard: Standard “General Technical Conditions for Corrugated Metal Hoses” (GB/T14525-93)

2. The bellows of the metal hose are made of chromium-nickel austenitic stainless steel. Pay attention to prevent pitting corrosion from nitrogen ions and corrosion damage from strong sulfuric acid.

3. After the user conducts a hydraulic test on the equipment and pipeline system equipped with the metal hose, attention should be paid to prevent rust block impact and deposition of chloride ion sediment, causing corrosion and mechanical damage.

4. During installation, prevent splashing during welding and mechanical damage to the metal hose to prevent leakage.

5. Sealed pipeline systems should strictly follow safety operation procedures to prevent soft hose detachment or bursting caused by improper

operation or other factors leading to overpressure.

6. Please carefully digest the installation methods and examples of metal hoses, and strictly follow the correct schematic installation and use.
