Installation of large air separation plant

The installation of large air separation plant is an important link between the design and manufacture of ASU and the start of production, The quality of the installation work of Dear Air Separation ensures the operational index and safety of the whole set of air separation equipment in the future. In recent years, domestic and foreign manufacturers have encountered due to the quality of the installation of substandard ASU users and equipment manufacturers caused significant economic losses on both sides of the situation. Large air separation plant must be installed and constructed in strict accordance with relevant national standards and industry standards. Requirements for the installation company:

1. should have the appropriate level of pressure piping installation qualification, bear the pressure vessel, pressure piping site manufacturing and installation of the installation unit must have the corresponding categories of the State Bureau of Quality Supervision, Inspection and Quarantine approved varieties of pressure vessels, pressure piping manufacturing, installation license;
2. the installation unit should have a sound quality assurance system. And can effectively implement, should have installed medium and large air separation equipment performance;
3. installation units must have experienced project managers, quality engineers, welding inspectors, each profession should be equipped with a certain number of professional engineers to guide the installation work, the number of argon arc welders and licensed projects should be able to meet the requirements;
4. installation team should have the appropriate qualification certificate welders and nondestructive testing personnel. Prohibit welding without a certificate or cross-level irregularities, the number, level and certification of nondestructive testing personnel should be able to meet the needs of the regulations;
5. the installation unit should have a variety of equipment to meet the needs of the installation, including equipment for surface cleaning and quantitative analysis instruments, should establish the installation quality system and pay for its implementation:
6. should have to meet the minimum requirements of the site welding wind, rain, frost protection measures, work equipment, equipment can meet the needs of the installation.

Rigorous design review is an important step in the installation of air separation plants.
