Installation of the hose station

Differences in color codes, differences in interface types, especially the interfaces for factory air and nitrogen

For your question, you may refer to the relevant provisions on \"Installation\" in Section 2 and on \"System pressure selection and pipe end connection\" in Section 3 of \"HG/T 20570.13-95 Installation of public material stations\". The key points to note are summarized for your reference. 2.0.1 Materials to be provided at the common material station 2.0.1.1 A common material station usually requires steam, water, compressed air, and nitrogen. The steam, water, compressed air, and nitrogen supplied at the common material station must be separated from those used in the actual production process; in other words, the common material station must have dedicated pipelines for these substances, so that it can continue to function properly even when the plant is shut down. 2.0.2 Location of common material stations: The locations of these stations are determined based on areas with a radius of approximately 15 meters; the location and number of such stations are chosen so that they can serve the entire facility. The locations specified for the utility material stations in the following items represent the usual installation sites; if process requirements dictate a specific location, the stations should be installed according to those requirements. 2.0.3.1 Typically, a utility material station consists of four types of material systems, namely water, steam, compressed air, and nitrogen; the order in which they are arranged is usually steam, water, compressed air, and nitrogen. This arrangement is done to facilitate construction and safe operation. 2.0.3.2 Installation height of the common material station: The installation height of the quick connector at the pipe end of the common material station is usually 0.8–1.2 m. 3.0.1 Selection of pressure for the utility material system: Generally, the pressure in the material systems within utility material stations is as follows: Water – 0.2 to 0.4 MPa (gauge); Steam – 0.2 to 0.4 MPa (gauge); Compressed air – 0.3 to 0.6 MPa (gauge); Nitrogen – 0.3 to 0.6 MPa (gauge). 3.0.2 Pipe end connection methods: For the connections between hard pipes and flexible pipes in various systems of utility material stations, quick connectors are generally used; for rubber pipes, pyramid-shaped pipe connectors can be employed. 3.0.3 The sizes of the isolation valves for various media at the common material station range from DN15 to DN50, depending on the characteristics of the installation. The model specifications of the valve and pipe connections for various media at the common material stations can be intentionally made different, while the order in which the media are arranged at each common station must remain consistent; this helps to prevent accidents from worsening due to the incorrect connection of media in emergency situations.

Additional note: The service radius for each hose station is 15m; hose stations should also be installed on the tower.

The setup for the hose station is a radius of 15m; for details, please refer to the HG-T 20570.13-95 standard

Our hose stations usually have compressed air, water, and low-pressure steam. This needs to be set according to the characteristics of each company.
