Class 150 pipe fittings are used in piping system to alter directions and to make connections among the equipment. These fittings are used to regulate the low-pressure fluid or gas. It is usually used for non-critical and low cost applications. The size ranges are from 1/8” to 4” (DN6 to DN100).
For example, a Class 150 flange is rated to approximately 270 PSIG at ambient conditions, 180 PSIG at approximately 400°F, 150 PSIG at approximately 600°F, and 75 PSIG at approximately 800°F. In other words, when the pressure goes down, the temperature goes up and vice versa.
When we consider pressure rating 150, it means that safe working pressure for this pipe, flange or valve at given temperature for given material is 150 pound per square inch. See below the some of the common way to refer the pressure rating 150 valve; Class 150# valve. 150 pound valve. 150 pressure rating valve.
A Class 300 flange is rated to a higher pressure than a Class 150 flange, because a Class 300 flange is constructed with more metal and therefore can withstand more pressure. However there are a number of factors that can impact the pressure capability of a flange.
Class 125 and Class 250 are cast iron flanges and flanged fittings while Class 150 and Class 300 are ductile iron, steel or stainless steel. Hence, ANSI/ASME B16. 1 Class 125 flanges are made from cast iron, ANSI/ASME B16. 5 Class 150 can be made from steel or stainless and ANSI/ASME B16.
Likewise, in the case of an ASME Class 150 valve, you can use it to an upper limit of 1.96 MPa within a temperature range of -29 to 38°C for WCB material. Note that the nominal pressure is not the maximum permissible pressure.
What is Freight Class 125? Freight Class 125 is the classification most appropriate for small household appliances, pictures/posters in boxes, exhibit booths and/or vending machines that weight 7-8lbs per cubic foot.
Black Class 150 / Schedule 40 Pipe Fittings - NPT.
Class 150. If the temperature for Class 1 150# flange is < 100 degrees Fahrenheit, the maximum pressure for flanges is 285 psi. If the temperature for Class 1 150# flange is 200 degrees Fahrenheit, the maximum pressure for flanges is 260 psi.
The pressure rating defines the maximum allowable pressure that a flange can withstand at defined tempera- tures. According to the ANSI/ASME B16. 5 specification, there are the following seven flange pressure classes: Class 150#, Class 300#, Class 400#, Class 600#, Class 900#, Class 1500# and Class 2500#.
Class 150 pipe fittings are used in piping system to alter directions and to make connections among the equipment. These fittings are used to regulate the low-pressure fluid or gas. It is usually used for non-critical and low cost applications. The size ranges are from 1/8” to 4” (DN6 to DN100).
Class 150 threaded fitting is mainly used to tighten up with fittings to extend the flow direction. Class 150 Threaded fittings are made to conform to ASTM A351 CF8M/316 Stainless Steel material.
If we consider a pressure rating of 150, the safe working pressure for this pipe flange or valve at a specific temperature for a given material is 150 pounds per square inch.
the class 300 flange (bigger and stronger, but with the same bore size) withstands 570 psi at the same temperature of 600 degrees F°
A compact and lightweight ball valve with a Class 300 pressure rating. It is ideal for applications with temperature conditions of -20°F (-29°C)- 450°F(232°C). It comes with a blow-out-proof stem design, an anti-static device and can be automated using an ISO 5211 mounting pad.
150# fittings are suitable for low pressure application such as water, oil, and gas. As implied by its name, the pressure rating for 150# fittings is 150 PSI, with NPT and BSPT available thread.
When trying to determine the flange rating of a pump, the best method is to look for a stamp printed onto the flange. If one is not visible, or it is worn, then start by counting the number of bolt holes. This will point you to a narrower range of flange sizes in the chart below.
Molded CLASS 150 Flange fittings are coupling devices designed for joining IPS (Iron Pipe Size) plastic piping systems, where frequent disassembly may be required, and can be used as a transitional fitting for joining plastic to metal piping systems.
“Class” pipe is a different labeling system. Rather than categorization by wall thickness, the “class” designation rates the internal pressure that the pipe can take instead. So a “class 200″ pipe can take 200 psi, no matter what the diameter of pipe is. If it is 10″, it takes 200 psi. If it's 3/4”, it takes 200 psi.
Nominal Bore 6 inch (DN 150 mm), Outside Diameter 168.3 mm
Schedule 40 has same dimensions as STD.
ANSI 150 also known as ASME B16. 5 ANSI 150. ANSI is abbreviation for American National Standards Institute. This flange table is most common in mining, Oil, Gas & refining industries. Advanced Piping Systems manufacture ANSI Flanges to suit both Mining & high spec for refining of Gas & minerals.
1 class 125 has a pressure rating of 184 psi, B16.
The Class 250 flange is an ANSI /ASME specification, not an AWWA, and it means the joint can withstand 250 psi at 373 degrees Fahrenheit.
