Such as glass-lined reactor pressure vessel tanks leak test after hydrostatic testing and jacketed vessels were qualified hydrostatic test. For pressure vessels enamel pot 400L, air tightness test pressure is generally 1.0 times the design pressure, the vacuum vessel enamel tank tightness test pressure should be 0.1MPa. The test gas should be dry and clean air, nitrogen or inert gas. Gas temperature of not less than 5 ℃. During the test, slow step to the required test pressure after packing enamel reaction tank 100L, simultaneously with the foaming agent (such as smear soapy water, etc.) and check for leaks. After the tightness test is completed, the need for glass-lined faces were resistant to high voltage test retest. Glass-lined reactors and other glass-lined equipment is enamel containing high silica (glass-lined), spraying the inner surface of the reaction tank tank steel container, and then burned at high temperatures (the enameling process), makes glass-lined securely Adherence to become a composite steel container products on the inner surface of metal. Therefore, it is the stability of the dual advantages of metal and glass strength, is a very good corrosion-resistant equipment. At present, more and more being used in the pharmaceutical, chemical, food and other industries. Enamel lid, Cheng Ming Chemical (certified), enamel pot by Chemical Equipment Co., Ltd. Shandong Cheng Ming. Chemical Equipment Co., Ltd. Shandong Cheng Ming (www.cmchemical.net) is an industry leader in Shandong Zibo, chemical equipment, over the years, the company implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs.
