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.

The molecular sieve used in oxygen generators is the zeolite molecular sieve. It is a crystalline silica and aluminate polyhydric compound. Molecular sieves have a uniform pore size and their main function is to sieve molecules. There are three main types of molecular sieves: A, X and Y. The 13X molecular sieve is the only adsorbent currently used in liquid air separation plants. Any molecules that can be adsorbed on 3A, 4A and 5A molecular sieves can be adsorbed by 13X molecular sieves. It is c...

Pressure test before valve installation 1. In the warranty period, those with the certification and the sealing surface is intact can no longer conduct the strength test alone, but only the air tightness test can be taken before installation. 2. Within the warranty period, it has the certificate, and its sealing surface has defects such as corrosion and damage. After treatment, it must carry out the air tightness test. 3. Outside the warranty period, those with certification and intact sealing surface shall be subject to air tightness test before installation. 4. For valves that need to be degreased and disassembled on site, air tightness test shall be conducted separately before installation. 5. The safety valve shall be sent to the local quality inspection department of the project for verification before the end of installation and commissioning.
