The term \u201cPressure vessel\u201d is refers to a closed containers designed to store fluid at a pressure greater than 15 psi or 1 atm. This pressure can be imposed by the internal pressure caused by the fluid or the external pressure created by the direct or indirect heating of the vessel. Pressure gradient is a serious parameters in designing a pressure vessel. \u00a0In fact, the more pressure difference in the pressure vessel, the more possibility of explosion and destruction.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

The term \u201cPressure vessel\u201d is refers to a closed containers designed to store fluid at a pressure greater than 15 psi or 1 atm. This pressure can be imposed by the internal pressure caused by the fluid or the external pressure created by the direct or indirect heating of the vessel. Pressure gradient is a serious parameters in designing this product. \u00a0In fact, the more pressure difference in this product, the more possibility of explosion and destruction. Considering the mentioned concerns, the design, construction and commissioning of these vessels are performed under legal supervision by official engineering associations. Maximum allowable pressure and temperature are two major parameters which distinguish the vessels from each other. HAVAYAR industrial group is one of the pioneering companies in employing universal standards for designing and manufacturing of pressure vessels. The mentioned procedure results in safety and operational assurance of this product.<\/p>

Types of pressure vessels<\/h2>

Pressure vessels can be clustered from different points of view as follows:<\/p>

  1. Layout: horizontal or vertical<\/li>
  2. Type of stored fluid: gas or liquid<\/li>
  3. Wall thickness: thin wall or thick wall<\/li>
  4. Tank geometry: spherical, cylindrical or conical<\/li><\/ol>

    Pressure vessels geometry<\/h2>

    Pressure vessels may theoretically exist in any shape, but cylindrical vessels are the most common type which are designed and manufactured by HAVAYAR industrial group. These tanks are made of a cylinder with two caps at the front and the end which is a typical design in pressure vessel industry. The geometric shape of the two caps is often in the form of a convex lens of Elliptical 2:1 type or torispherical.<\/p>

    Application of pressure vessels<\/h2>

    Pressure vessels are widely used in various industries. this product which are commonly manufactured in HAVAYAR have different applications which can be listed as: compressed air receivers, dryer towers, and nitrogen and oxygen generator adsorption towers. \u00a0It should be noted that the mentioned this product is commonly employed in the oil, gas and petrochemical industries.<\/p>

    Design and construction of pressure vessels<\/h2>

    These vessels can be designed and produced based on different standards, but the most referenced standard in our country is the ASME standard (ASME Boiler and Pressure Vessel Code), which is abbreviated BPVC for short.<\/p>

    The construction procedure of the mentioned vessels include rolling steel sheets by rolling machine and welding them to the pre-constructed heads. During the construction, welding procedure is very vital as the temperature rise in welding point can change the properties of the material and lead to an irreparable obstacles unless procedures to be prepared and considered before welding. These needs lead to the production of this product welding procedure so called called WPS, which is the abbreviation of Welding Procedure Specification. The tests performed on pressure vessels mainly include one or more of the following tests:<\/p>
