LPG tanks introduction and notes
Subject spherical LPG tank is a spherical shell, which is the storage of materials and material to withstand the operating pressure and static pressure of the liquid column member, according to a certain size by a number of pre-pressed into a ball panel assembly groups welded. Spherical bearings are tank structural member for supporting the body weight and the weight of the storage material can be divided into column bearings and ball bearings into two categories. Using the most common is the tangent of the equator column support. Tank structure is not complicated, but it's difficult to produce tanks and tank installation than other types. The design and use of the tank to ensure safe and reliable.
Rational design tank structure must consider various factors: the nature of the loading material, the design temperature and pressure, materials, manufacturing technology and equipment, installation methods, welding and inspection requirements, easy to operate and reliable, and so the natural environment influences such as . To do meet the technical requirements, we have sufficient strength and stability, and the structure as simple as possible, so that pressing, Group installation, welding and inspection, operation, monitoring and maintenance easily measured.
Note 1, the safe operation of LPG tanks mm_ + 0 liquefied gas storage tank in order to prevent excessive temperature, overpressure, should control the use of pressure and temperature. Ultra mild overpressure reasons liquefied gas storage tanks are the following: (1) To prevent operational errors operational errors, it should be listed on the key operating device, clearly marked with text or indicate the direction of opening and closing valves on the card , opening and closing state, and precautions. Measures (2) to prevent excessive filling of liquefied gas filling overdose include: strict accordance with the prescribed amount of storage filling and found super equipment, should seek immediate loading will exceed the amount withdrawn; filling all the instruments used must be regularly inspected, level Total to regularly wash; there as residue in the container, should be recognized in its filling volume, its weight can not be ignored; when the ambient temperature rises, should be spray cooling. 2, liquefied gas storage tank maintenance
