Characteristics and usage of carbon steel weld neck flange

  Carbon steel weld neck flange does not have to use stainless steel bolts, the use of stainless steel bolts is to facilitate disassembly, in some cases can not fire or other special occasions can also be selected.

  Carbon steel weld neck flange in this session of a variety of new products are constantly emerging, in the steel pipe industry such as steel pipes are also constantly developing to create high-end products to sell steel pipes.

  In fact, ASTM A182 RF Carbon Steel Weld Neck Flange is also in the steel range to develop slowly, carbon steel weld neck flange blank is also in the production of carbon steel weld neck flange left over from the rough, but these carbon steel weld neck flange steel parts left behind to produce carbon steel flange blank.

  Carbon steel flange is divided into butt welding with neck, flat welding with neck, socket welding and threaded flange is generally made by forging or rolling process.

  When manufacturing steel plate or section steel, the following requirements must be met:

  1. It should be cut into strips along the rolling direction of the steel and welded into rings by bending and butt welding, and the surface of the steel should be cylindrical. No steel plate can be directly machined into carbon steel weld neck flange.

  2. the steel plate should be examined by ultrasonic wave without delamination defect.

  3. Full penetration welds shall be used for the butt welds of the rings; carbon steel bolts shall not necessarily be used with insulating gaskets and buckets, plus insulating gaskets and buckets only for possible electrified or pipeline fluids are flammable and explosive occasions, the use of stainless steel bolts should also be coupled with insulating gaskets and buckets.
