Face Type of a WELD NECK flange
What is a Weld Neck Flange and its 2 different shapes
The smooth transition between the flange and the hub combined with the strength of the butt weld joint, allows the flange to be used in extreme conditions of cyclic loading, bending and temperature fluctuations.
A flange can be defined as a method that helps in connecting pipes, valves, etc., to form a full piping system. There are six flange classes ranging from #150 to #2500. Governed by B 16.5 standards, the ASME B16. 5 Class 300 Flange provides a pressure capacity of 300Lb.

The descipton ,specification ,and advantages of a weld neck flange.
ASME B16. 5 is limited to flanges and flanged fittings made from cast or forged materials, and blind flanges and certain reducing flanges made from cast, forged, or plate materials. Also included in this Standard are requirements and recommendations regarding flange bolting, flange gaskets, and flange joints.

Alloy Steel: ASTM A182 F11 / 12 / 5 / 9 / 91 / 92 Stainless Steel: ASTM A182 F304/304L/304H, 316/316L, 321, 310S, 317,347,904L, 1.4404, 1.4437.
There are varies advantages of stainless steel flange: Resistant to corrosion and staining Low maintenance Bright familiar luster Steel Strength
Slip on flange can be made by forging, steel cutting, casting and etc. Among these manufacturing types, the forging type gains the best quality and also the most common use.
Slip on flange, also called SO flange. It’s a kind of flange slides over the pipe with internal design is slightly larger than the pipe. Since the inner diameter of the flange is slightly larger than the outer diameter of the pipe, the SO flange can be directly connected to equipment or pipe by fillet weld at the top and bottom of the flange. It is used to insert the pipe into the inner hole of the flange.
There are various material grade for ASTM A182 stainless steel flange: F304/304L/304H, 316/316L, 321, 310S, 317,347,904L， 1.4404, 1.4437.
A flange can be defined as a method that helps in connecting pipes, valves, etc., to form a full piping system. There are seven flange classes ranging: #150, #300,#400, #600, #900, #1500 #2500.
The common material grade of stainless steel ASTM A182 contains F304/304L/304H, 316/316L, 321, 310S, 317,347,904L， 1.4404, 1.4437.
Stainless steel flange, also called SS flange, it means the material of flange is stainless steel. Common material standards and Grades are ASTM A182 Grade F304/L and F316/L, with pressure ratings from Class 150, 300, 600 etc and to 2500.
flange type: Weld Neck Flange ( WN),Slip-on Flange (SO), Threaded Flange (THD),Socket Weld Flange (SW),Blind Flange (BL),Lap Joint Flange (LAPJ),Plate flange (PL)
Common material grade for stainless steel flange: ASTM A182 F304/304L/304H, 316/316L, 321, 310S, 317,347,904L， 1.4404, 1.4437.
Class 300 LAPJ flanges are used with lap joint stub end.The pressures for ASME B16.5 forged flanges including 150LB,300LB,600LB,900LB,1500LB12500LB.
