ANSI/ASME B16.5 Class 300 Plate Flange
- PRODUCT DETAIL
A plate flange is also known as flat flange or plain flange,some people called it plate slip on flange.It lookes like a flat circular disk with inner holes and bolt holes on it,that is weled onto the end of a steel pipe and allowing it to be bolted to another steel pipe. Plate flanges (flat flanges or plain flanges) are fixed to the pipe by fillet welds at the bottom and top of the flange. The inner hole of plate flange is a little bigger than the pipe outer diameter. Plate flanges (flat flanges or plain flanges) are not suitable for high pressure applications because the welding method is fillet weld. Flat flanges are commonly used for fuel and water pipelines,the two flanges are bolted together and gaskets are placed between them.
Plate/Flat Flange-rf stainless steel pipe flanges
ANSI/ASME B16.5 (In ANSI/ASME B16.5 standard,there is no plate slip on flange,only hub slip on flange in it,but in different projects the ANSI B16.5 plate flange is used a lot for decrease the cost of the projects.The ANSI/ASME B16.5 plain flange should have the same dimensions and pcds with the slip on flange,the only difference is without a hub on the flange.)

Marking and packing of plate flanges:
All flanges are typed with grade, batch number, size, standard and our trademark.For special requirements, we can also make custom marks on our products.
Usually, our products are packaged in wooden cases or pallets. We also take into account the transportation conditions of the products to do anti-corrosion measures and anti-damage protection for pipe products, such as brushing anti-rust paint or galvanizing, wrapping plastic film, wrapping cloth, etc., to ensure that the products will not be damaged or rusted during transportation.
Hebei Haihao Group as a first class manufacturer of plate Flange(PL Flange) in China,supplys a variety of steel flanges to satisfy our customers’ specifica requirements,which include different size,different schedule,different pressure and different finish faces. Our products are produced strictly according to the required standard. Our raw material for plate flanges all are purchased from big steel companies which can make sure the material in a high quality.
