The information presented above are average values and not a guarantee of maximum values.The ASME code suggests a safety factor of four (4).Working pressure is 25% of Burst Pressure in temperatures ranging from -20☏ to 100☏.Theoretical Tube Burst Pressure Ratings Size (Tube OD) It is theoretical because the true burst pressure of these tube fittings cannot be accurately measured without a way to properly seal them off. With all this being said, we have put together a theoretical tube burst schedule in the table below. Standard: -15☏ to 437☏ (-26☌ to 222☌)ĭouble Bolt High-Pressure Clamp Ratings Size (Tube OD) Displayed are the recommended pressure ratings in Pounds per Square Inch (PSI) at varying temperatures. In the case of clamps, we have selected our strongest clamp, the double-bolt high-pressure clamp. With regard to temperatures, the gasket will fail before anything else.īelow are two tables to reference for both clamps and gaskets regarding temperature and pressure ratings. In the case of higher pressures, it’s the clamp that can fail. This point represents the weak link in the chain for both pressure and temperature. At this point, there is a gasket and clamp used to connect the two fittings in place. Tri-clamp fittings are weakest at the connection points where one flange ferrule connects with another. You’ve no doubt heard the saying: “A chain is only as strong as its weakest link.” The same logic applies for tri-clamp fittings. Naturally, the question arises about our fittings and their ability to withstand both. Occasionally, they will be working in processing environments where high temperatures, pressure or both are required. In Oil and Gas, A53 grade pipes are used in the structural and non-critical applications.Tri-Clamp Fittings Burst Pressure and Temperature RatingsĬustomers often ask about the temperature and pressure ratings of our tri-clamp fittings. These pipes can be bare pipes without any coating, or it may be Hot-Dipped or Zinc-Coated and manufactured by Welding or by a Seamless manufacturing process. ASTM A53 Grade B is more popular than other grades. Tips: ASTM A53 covers seamless and welded steel pipe with nominal wall thickness. Class is the pressure rating of the American standard seamless steel pipe, which is converted to MPa: Class150 is equivalent to the American standard pressure rating of 2.0Mpa Class 300 is equivalent to 5.0Mpa Class 400 is equivalent to 6.8Mpa Class 600 is equivalent to 11.0 Mpa Class 900 is equivalent to 15.0Mpa Class 1500 is equivalent to 26.0Mpa Class 2500 is equivalent to 42.0Mpa. The calculation in this table is based on GB/T 20801.1-2006 Pressure Piping Specification Industrial Pipingĥ. The seamless steel pipe standard adopts GB17395-2008 seamless steel pipe size, shape, weight and allowable deviation.Ĥ. Pay attention to relevant specifications and requirements when selecting.ģ. The applicable temperature range of the seamless steel pipe wall thickness in the table is -20~+150℃, the corrosion margin is 2.0mm for carbon steel, and 0 for stainless steel seamless pipe. SS2 stands for stainless steel seamless steel pipe, applicable to 304 (0Cr18Ni9) and 316 (0C17Ni12Mo2) in GB14976 "Stainless Steel Seamless Steel Pipe for Fluid Transport" Ģ. SS1 stands for stainless steel seamless pipe, applicable to 304L (00Cr19Ni10) and 316L (00C17Ni14Mo2) in GB14976 "Stainless Steel Seamless Steel Pipe for Fluid Transport" In the table, CS means carbon steel seamless pipe, applicable material GB8163 "Seamless steel pipe for fluid transportation", GB3087 "Seamless steel pipe for low and medium pressure boiler", GB6479 "High pressure seamless steel pipe for fertilizer equipment", GB9948 "Petroleum 20# in "Seamless Steel Pipe for Cracking"
