Q:What is the silk flange?
Generally refers to the pipe, pipe connections, the commonly used way is divided into: silk and flange two. The screw thread is a screw thread connection; the flange is to weld the two end of the connecting pipe on the convex ring, drill a few holes, and penetrate the bolt in the hole to connect.
Q:What is a flange in machining and why is it named?
Some pipe fittings and equipment have their own flange, but also belong to flange connection.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.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 is the SO flange?
Hubbed flange. The other can query HG20592-2009, there are inside.
Q:About flange 5
Should mark "DN", is the nominal diameter of the code.Is the nominal diameter size after the roundness of the numerical repair to the mantissa, in order to simplify the mark.Germany, China ISO, nominal diameter are DN.
Q:What's the flange size?
Is the square distance is under the eyes of the flange size
Q:WoW World Mission, where is the French die cutter?
First you go to the flange out from the portal. The past is Ireland, also ran for,Then you don't go down to the ground, go first to the pit, trigger the task, then you can find the litter in the range shown on the minimap, but the quantity and the density are not high, and you need to look for it patiently
Q:Where is the identification shop in flange city (coordinate)?
Mrs. Katie's store 196,78 identifies thingsGlima's home 216,43 appraisers work on the jobStrong brother grocery 191,38 appraisers inaugurationI don't know which one you need
Q:Who can tell me what "DN" and "PN" mean in flanges, and what does PN16 stand for?
DN----- through the flange -- such as pressure DN15. with Phi 18 DN25. with 32 DN30. diameter pipe pipe with pipe ----------PN----- Phi 38 maximum value, the unit is "MPa, 1 MPa and cm - equivalent to 10KgPN16 refers to the pipe and the flange matched bearing pressure approximately 12 MPa. The equivalent of 120Kg - and cm
Q:What is the standard version of flanges?
The flange of the material according to the production of material can be divided into: WCB (Tan Gang), LCB (low temperature Tan Gang), LC3 (3.5%, WC5 (1.25% chromium nickel steel) 0.5%, WC9 (2.25% Cr Mo steel), C5 (5%), C12 (% Cr Mo) 9% Cr 1% mo (4), CA6NM (12% steel) CA15, (4) (12% CR), CF8M (316 stainless steel, CF8C (347) CF8 (stainless steel), stainless steel 304), CF3 (304L stainless steel), CF3M (316L stainless steel), CN7M (alloy steel), M35-1 (Meng Naier), N7M (Haast B, CW6M nickel alloy nickel alloy (Hasta) C (CY40), Inconel) flange connection (flange, joint) composed of a pair of flanges, a gasket and a plurality of bolts and nuts. Gasket on the flange sealing surface between the two, tighten the nut, the gasket on the surface pressure reaches a certain value after the deformation, and fill uneven sealing surface, the tight connection. A flange connection is a detachable connection. The connecting parts can be divided into containers, flanges and tubes; in accordance with the structural type, there are integral flanges, looper flanges and threaded flanges. There is a common integral flange flange and butt welding flange. Less rigid flange, suitable for pressure P is less than or equal to 4MPa occasion; also called high neck flange welding flange, large rigidity, suitable for high temperature pressure. Flange sealing surface of the three types: planar sealing surface for the pressure is not high, medium non-toxic occasions; uneven sealing surface, suitable for higher pressure situations; the sealing surface of the tenon, suitable for flammable and explosive, toxic medium and high pressure situations.
Q:One side is flat plate and side hubbed flange can be connected to it
Please check their respective materials, and then decide whether to solder, similar materials can be welded, it is also necessary to pay attention to the welding process Oh!
