Check ANSI B16.11 Class 3000 Stainless Steel Fittings Pressure Rating/Material Specification And ASME B16.11 Class 6000 Socket Weld Fittings Manufacturer In India.
The class 3000 fittings consist of multiple components made of stainless steel, like 90-degree elbow, straight and reducing tee, cross, steel pipe coupling, cap, union, and lateral. The Class 3000 Stainless Steel Fittings are used only in conjunction with the ANSI pipes, which are available in a similar size range. The Class 3000 fittings are used for various industrial purposes; the ASME standard depicts safety and quality. The High-Pressure Class 3000 Fittings Dimensions are available in size from NPS ⅛ to NPS 4. Biggest Manufacturer Of Class 3000 Stainless Steel Fittings In India.
The class of a fitting depicts the maximum pressure the equipment is capable of handling. The Class 6000 Threaded Fittings are used for pipes in schedule 160. Similarly, the 6000 Lb Pipe Fittings are for pipes that have a thicker wall.
The Class 9000 Socket Weld Fittings is a pipe fitting component inserted in the recessed area of a valve or flange. These are used for pipes with a smaller diameter, generally whose diameter is less than or equal to NPS 2. The Class 6000 Forged Steel Fittings are used in various industries like oil and gas, petrochemicals, etc., and these equipment are pretty durable. The Socket Weld / Threaded Class 3000 Fittings are made of high-quality materials, making them perfect to be used in harsh environments. Depending on the material with which these are made, they are anti-corrosive, durable, and can last for many years.
