Detailed Information

Ansi B16 5 Class 2500 Flange Dimensions permit the ribs to hold a portion of the most extreme pressing factors excerpted in pipe frameworks. The standard ANSI B16.5 incorporates ribs of ½ creeps to 24 crawls in ostensible sizes. The pressing factor limits of the spines fluctuate from 150lb to 2500lb. The 2500 Lb Flange Dimensions permit the spines to go through exceptionally high pressing factors up to 2500lbs. To accomplish this high pressing factor limit, ideal material grades must be chosen. There are various sorts of ribs in this standard like slip on ribs, daze ribs, weld neck ribs and lap joint ribs.

The Class 2500 lb weld neck flange dimensions are measured in imperial or metric measurements. The socket weld flanges are used in applications where the pipe has to be held onto prior to welding. Also the socket weld flanges provide extra space, surface and grip to the connection. The 2500 lb blind flange dimensions allow for the blind flanges to be connected to the end of a pipe and to close the pipeline either temporarily or permanently. The connections that need regular maintenance use the blind flanges for easy opening and closing of the pipelines. The Class 2500 Flange is one of the highest pressure rating flanges. For this high alloy materials, duplex and carbon steel materials along with stainless steel materials are used. The ASME B16.5 Class 2500 Flange is used in water lines, oil and gas, petroleum, food processing, heat exchanger, power generation oil drilling and other applications as well.

The Class 2500 lb weld neck rib measurements are estimated in magnificent or metric estimations. The attachment weld ribs are utilized in applications where the line must be clutched preceding welding. Additionally the attachment weld ribs give additional room, surface and hold to the association. The 2500 lb daze rib measurements take into account the visually impaired spines to be associated with the finish of a line and to close the pipeline either briefly or for all time. The associations that need ordinary support utilize the visually impaired ribs for simple opening and shutting of the pipelines. The Class 2500 Spine is one of the greatest pressing factor rating ribs. For this high compound materials, duplex and carbon steel materials alongside treated steel materials are utilized. The ASME B16.5 Class 2500 Spine is utilized in water lines, oil and gas, oil, food handling, heat exchanger, power age oil penetrating and different applications also.
