Class 3000 Threaded Pipe Fittings

View Class 3000 Stainless Steel Fittings Pressure Rating, Check 3000# Fittings Dimension

3000# NPT Fittings are of a particular pressure class that is considered high pressure service. Rajveer Stainless And Alloys is a manufacturer and supplier of pipe fittings in the class 3000 stainless steel fittings pressure rating and others. The pressure classes indicate how much pressure the pipe fittings can withstand. This is important to know because the fittings shouldn’t be used with applications that have more pressure risks than the specification. The class 3000 is a high pressure specification and it is used in high pressure systems such as heat exchangers, boilers, power plants and in hydraulic systems.

Class 3000 Pipe Fittings

Manufacturer of Class 3000 Stainless Steel Pipe Fittings & 3000# NPT Fittings

The 3000# Fittings Dimension varies from application to application. Usually, these are of large diameter pipes. The Class 3000 Stainless Steel Pipe Fittings are forged, rolled or welded during production. We manufacture the 3000# Pipe Fittings for use in the water supply, irrigation, oil and gas, petroleum, petrochemical, power plant and in other high pressure services. Most of these fittings are of B16.11 standard which covers forged steel fittings. They could be of socket weld or threaded types. This class can include alloy steel or carbon steel. Please contact us for further information and pricing on the Class 3000 Fittings.

Difference between class 3000 threaded fittings and CL 3000 Buttweld pipe fittings

Buttweld is one of the most common forms of welding in pipe fittings. The buttweld allows the fittings to be fitted with welding resulting in a stronger connection. The threaded fittings come in handy where welding is not possible or not preferred. There pipes usually have make threads and the fittings have female threads. The two are fitted with the help of threads. There are classes that indicate the pressure capacities of any product. The class 3000 is a high pressure class. So the difference between a class 3000 threaded and buttweld fitting is really the thread.
