Gas Grades and the Importance of Purity<\/strong><\/p>\r\n

One of the most important criteria for selecting a gas is its purity level. Gases are produced in various grades to meet the needs of general industries, sensitive production lines, and research centers. The higher the gas purity, the lower the level of impurities present. Selecting the appropriate grade is very important and can directly affect the accuracy of results and the quality of the final product.<\/p>\r\n

For example, in the TIG welding process for aluminum, grade 3.5 is sufficient, but for GC analysis in a pharmaceutical laboratory, grade 5.0 is required. If you are unsure about selecting the right grade, consult our experts.<\/p>\r\n\r\n

Selection Guide by Industry<\/strong><\/p>\r\n

Keep in mind that choosing the wrong gas \u2014 both in terms of process quality and safety \u2014 will be costly. To avoid unnecessary expenses, find your industry to see which gas and grade is suitable for you.<\/p>\r\n

How Gas Supply and Delivery Works<\/strong><\/p>\r\n

\u26aa Nationwide Coverage and Delivery Across Iran<\/strong>\r\nAll specialty, industrial, and laboratory gases are loaded in high-pressure cylinders or cylinder pallets (bundles), in full compliance with safety protocols, and shipped to all of Tehran and every province in the country.<\/p>\r\n

\u26aa Flexible Supply Options<\/strong><\/p>\r\n

Periodic and Contract Supply (for organizations):<\/strong> For factories, hospitals, medical centers, and laboratories that require continuous, uninterrupted gas injection into their lines, regular scheduled supply contracts are established to prevent any stoppage in production processes.<\/p>\r\n

One-Time and Partial Order Placement:<\/strong> For temporary projects, small workshops, or irregular orders, the ordering process is completed by phone or through the website's online forms as quickly as possible.<\/p>\r\n

Collaboration on Tenders and Large-Scale Projects:<\/strong> To meet the needs of companies participating in government and private tenders, all technical documentation, laboratory gas analysis, standard certificates, and official pro forma invoices (in compliance with tax regulations) will be provided.<\/p>\r\n

Organizational Supply and Government Tenders<\/strong>\r\nFor organizational contracts, government tenders, and bulk orders, the Bonyan Gas sales team provides technical documentation, standard certificates, and official invoices.<\/p>\r\n
