steel flange OEM for weld on pipes

Q: Where is the difference between the double flange limit expansion joint and the double flange transmission joint?: From the model:Double flange limit expansion joint is VSSJA-2, referred to as B2F; double flange transmission joint is VSSJAF, referred to as C2FFunctionally:Double flange limited telescopic joint is mainly used in the allowable displacement range absorb axial displacement and axial pressure pipeline thrust, loose connection is especially suitable for the pipeline vibration or have a certain inclination and turning in. It can prevent the pipeline due to excessive displacement caused leakage and damage compensation joint.

Q: Please describe it in your own words, not in the written language of Zou Zou.What's the flange?: 1 flanges are generally used to connect two pipes or pipes and valves with disc parts.2, flange welding is the connection of flanges and pipes.3. Fillet welds: welds welded along the line of intersection of two straight or nearly straight parts, as shown in Fig.4 so you weld the flange is fillet weld.

Q: SB 1379-NP15 which flange standard is the flange diameter, pitch, thickness, screw hole number and diameter?: Flange, threaded connection (wire), flange and welding flange. Low pressure small diameter wire connecting flange, high pressure and low pressure big diameter all use welding flange, different pressure flange thickness and connection bolt diameter and quantity are different.According to the different grades of pressure, the flange pad also has different materials, from low pressure asbestos pad, high pressure asbestos pad to metal pad.1. to classified material of carbon steel, cast steel, alloy steel, stainless steel, copper, plastic, Aluminum Alloy, argon Ge Lek, PPC etc..2., the production method can be divided into forging flange, casting flange, welding flange, roll flange (super type)3. makes the standard can be divided into national standard (Ministry of chemical industry standard, standard oil, electricity standard), American Standard, German standard, Japanese standard, Russian standard, etc..

Q: there is a pair of flange drawings, the above mark is 6-M12 evenly distributed 23 drill 24, what is the specific meaning?: Matching flange, tapping a face is threaded M23, and its matching flange is bolt free access, that is, the smooth surface, must be 24 diameter. Otherwise, it can't be tightened.

Q: WF face flangeI'd like to ask what flange form WF is,: The pattern of the flange sealing surface: plane (FF), sudden surface (RF), (MF), convex concave groove (TG) and ring junction (RJ). So far, there is no other form of sealing surface, is the concave and convex surface (MF) write backwards,

Q: What is the maximum pressure of the flanges RF and RTJ?: General toxic medium, are not recommended to use an ordinary plane flange and flange flange should choose picture, concave and convex surfaces or the sealing performance is better than the. ??For toxic media, as long as it is not extremely dangerous, the pressure grade <=1.6MPa, you can generally use the convex surface RF flange, 2.5MPa start, generally need to use concave convex flange. For extremely hazardous media, recessed flanges shall be used.

Q: Flange SO40-2.: Now the method is SO 40-25 M.Refer to HG/T20592-2009 steel pipe flanges (PN Series)

Q: In building engineering, what is called "flange" means detailed point?: According to the different grades of pressure, the flange pad also has different materials, from low pressure asbestos pad, high pressure asbestos pad to metal pad.Flange connection, easy to use, able to withstand greater pressure.Flange flanges are widely used in industrial piping. In the home, the pipe diameter is small, and it is low pressure and can not see the flange connection. In a boiler room or production site, flanges are connected to pipes and equipment.

Q: What flange is the SOFF flange?: IF integral flange, SW socket welding flange, TH threaded flange; loose flange ring PJ/SE welding, PJ/RJ welding ring flanges;

Q: RJ what flange is the sealing surface?: RJ is the flange ring connection surface.Flange sealing surface type:Full plane FFProjection RFConvex MConcave FTenon face TGroove surface GRing joint surface RJGeneral concave convex MFTongue and groove face TG
