Bolt two flat-surface flanges or two raised-surface flanges of the same size together with a gasket (sold separately) to create an access point in a pipe line.Flanges are for use with low-pressure applications in noncorrosive environments..Butt-weld flanges are also known as weld-neck flanges; the flange neck has a beveled end that,when flush to pipe,creates a trough for a strong weld.ASME B16.5 Welding Neck Flange - Piping PipelineJul 02,2019·According to ASME B16.5,the hub of the welding neck flange can be roughly divided into a tapered portion and a straight length.The straight length of 6 mm is machined to precisely match with the adjoining pipe so that the welding can be done conveniently.Weld neck flanges are bored to match the inside diameter of the adjoining pipe.
Two very important flanges such as weld neck flange and blind flanges are very commonly used in piping systems.The term B16.5 or B16 5 is used interchangeability and refers to same standard.However,the standard ASME B16 5 (ANSI B16 5) onlyASTM A106 Gr.B pipes,API 5L PLS1 and PSL2 pipes,ANSIHebei Haihao Group is one of biggest manufacturers specialized in the production of pipes,pipe fittings and flanges.We have 660 workers and staff members with a strong technical force,including 26 engineers,48 assistant engineers and 68 technicians.

Weld Neck Flange.A weld neck flange is a type of steel flange designed to transfer stresses to the pipe to reduce high stress concentrations at the base of the flange.Compared with other types,weld neck flanges are know for their tapered hub and gentle transition from flange thickness to pipe
Sep 20,2017·Another advantage of the welding neck flange is that it can be connected either to pipes and fittings,whereas socket weld flanges suit pipes only.THREADED FLANGE Threaded flanges are joined to pipes by screwing the pipe (which has a male thread,generally NPT per ASME B1.20.1 ) onto the flange,without seam welds (in certain cases,though Weld Neck Flange Manufacturers - ASME/ANSI WN FlangeA weld neck flange is designed to joint a piping system by butt welding i.e.by welding the pipe to the neck of the flange.The butt welded area can be easily examined by radiography.It helps in reducing the stress concentration from the bottom of the center.
For use with air,water,oil,natural gas,and steam.Weld Neck Flanges Class 300 can be circumferentially welded into the system at neck to allow easy radiographic weld integrity inspection.Matched pipe and flange bore improve flow characteristics.Ideal for use in critical applications.Forged flanges have a raised face.Weld Neck Flanges Manufacturers Suppliers Piping MaterialWeld Neck Flanges are well-known from other kinds by their extensive pointed centre and moderate evolution of width in the butt weld area,by connecting them with the pipe.Meanwhile the extensive pointed centre offers a significant support of the proper flange,from the position of resistance and strength to dishing.
Weld Neck Pipe Flanges Weld Neck pipe flanges are commonly produced and stocked in several different materials.They are often referred to as Butt Weld Flanges.When joining these to pipe,the neck is butted up to the pipe and welded,similar to welding two pieces of pipe together.Weld Neck Pipe Flanges Hayward Pipe Supply Co,IncWeld Neck Pipe Flanges.Weld Neck pipe flanges are commonly produced and stocked in several different materials.They are often referred to as Butt Weld Flanges.When joining these to pipe,the neck is butted up to the pipe and welded,similar to welding two pieces of pipe together.
Weld neck pipe flanges are typically provided with a raised face,flat face,or RTJ facing.When a raised face is necessary for weld neck pipe flanges,the standard height is 1/16 for weld neck pipe flanges under 400#.For weld neck pipe flanges of 400# and up,the standard weld neck pipe flange raised face height is 1/4.Weld neck flanges AWWA Standard flangeFlanges described in the AWWA C207-01 tables are intended for use with steel pipe,fittings or appurtenances meeting the requirements of ANSI/AWWA C200,ANSI/AWWA C208,ASTM A134,ASTM 139,or other equivalent standards.It is further intended that these flanges be attached by welding in accordance with AWWA C207-01 Sec.4.3.
