PRODUCT DETELS
Torispherical dished head ends made from stainless steel (SS304 or SS316) are commonly used in oil and gas tanks, boilers, and pressure vessels. Here's some information about these components:
Stainless Steel: Stainless steel is a corrosion-resistant alloy that contains a high percentage of chromium. SS304 (also known as 304 stainless steel) and SS316 (also known as 316 stainless steel) are popular grades of stainless steel used in various industries. Both grades offer excellent corrosion resistance, high strength, and good mechanical properties.
Torispherical Dished Head Ends: Torispherical dished head ends, also called torispherical heads or dished ends, are curved vessel ends with a shape resembling a portion of a sphere blended with a cylindrical section. They provide improved pressure distribution and reduced stress concentration compared to other head shapes. Torispherical heads are commonly used in pressure vessels, tanks, and boilers.
Application in Oil and Gas Tanks, Boilers, and Pressure Vessels: Torispherical dished head ends made from stainless steel are suitable for various applications in the oil and gas industry, including storage tanks, process vessels, and boilers. They are designed to withstand the pressures and temperature requirements of these systems while providing structural integrity and efficient pressure containment.
SS304 and SS316: SS304 and SS316 are stainless steel grades that differ primarily in their composition. SS304 contains 18% chromium and 8% nickel, while SS316 contains 16% chromium, 10% nickel, and 2% molybdenum. SS316 offers improved corrosion resistance, especially in environments with chlorides or acids, making it suitable for more corrosive applications.
When using torispherical dished head ends made from stainless steel (SS304 or SS316) in oil and gas tanks, boilers, or pressure vessels, it is essential to follow relevant industry standards and codes, such as ASME Boiler and Pressure Vessel Code or other applicable regulations. Adhering to these standards ensures the safety, quality, and performance of the vessel and its components.
