BHGH threaded hub flange

Q: Where is the difference between the double flange limit expansion joint and the double flange transmission joint?: Double flange dowel joint can transfer the pressure thrust of the connecting piece (blind plate force) and error compensation line, reduce the damage of axial thrust of piping systems and equipment. Mainly used to connect the pump, valve, pipe and other accessories loose.I have a friend, Gongyi West Village Xin Xin pipe fittings factory production of these two products, you can consult, and I hope that my answer can help you

Q: For flange who is more detailed explanation? For example, how to position?: The question is a bit difficult to answer. I use some commonly used criteria to explain it.The ASME B 16.5 -2009 defines the construction criteria for pipe flanges and flanged fittings, including the definition of the flange pressure grade, the temperature and pressure curve of the flange material, etc., and is a very detailed construction code. According to the two part of the flange, a flange sealing surface in the form, such as the process of the convex surface surface groove face ring joint face; two flange form, such as welding welding socket welding etc.!The definitions in EN ASME are similar to those in 1092-01-2007!. The difference is that the ASME defines a pressure rating of CLASS series EN, defined as the PN series, and differs in the size of the flange sealing surface and the flange form.HG/T 20592-2009, the latest 2009 edition of the Ministry of chemical flange standards on the basis of the largest reference to the definition of ASME and EN, but there are still differences. In EN 1092-01-2007, at the same level under different pressure, the thickness of the flange form may not be the same, but in HG/T we can clearly see that all the size of the flange flange form is used in EN integral flange thickness. Personal feeling of the Ministry of chemical engineering flange standard strict and logical, and EN and ASME still have a gap.

Q: Which flange is the front pipe case flange and the cylinder flange?: The front pipe case flange is the tube part, which is connected with the tube plate.

Q: WN, SO, BL, TH, LJ and SW are the abbreviations of what words are. How do you translate Chinese? Class 150 is the stress level. Does that mean the pressure is 150 Bar? Thanks: The 1 floor is written in English, but the translation is not professionalThese abbreviations refer mainly to the welding structures of flanges, necks and tubes or nozzlesWN [neck welding flange]Is [SO] hubbed flangeBL is [flange], also known as "blind plate.""

Q: What is the maximum pressure of the flanges RF and RTJ?: The use of with concave convex surface with tongue and groove face flange is basically the same. Ring groove sealing surface (RTJ) is mainly used in high temperature and high pressure or both high working conditions. In American Standard flange, commonly used in Class 600Lb (part) and 900Lb, 1500Lb, 2500Lb grade pressure. In the German standard and national standard, often used in PNl0.0, PN16.0, PN25.0, PN32.0, PN42.0MPa flanges.

Q: What role does Sino French play in the waterproof casing pipe?: With different thickness and the use of different bolt pumps and valves, and pipeline connection, these equipment locally, also made the corresponding flange shape, also known as the flange connection. In two planes in the surrounding the use of bolts with closed connecting parts, generally referred to as "flange".

Q: DN200 how many screws are there in the weld flange?: DN200 welding flange has 8 and 12 screw holes two kinds.According to JB/T81-59 standard:MPa0.6 below, the outer diameter 315mm plate thickness 22mm Phi 18 hole, 8 hole center Phi 280MPa1,0., the outer diameter 335mm plate thickness 24mm Phi 23 hole, 8 hole center Phi 295MPa1.6, the outer diameter 335mm plate thickness 30mm Phi 23 hole, 12 hole center Phi 295

Q: Oil seal flange: 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. A gasket is a ring made of a material that produces plastic deformation and has a definite strength. Most from the non metal plate gasket is cut down, or by professional plant size, the material for the asbestos rubber sheet, asbestos board, polyethylene plate; also useful thin metal plate (Bai Tiepi, stainless steel) asbestos nonmetal materials such as wrapping made of metal gasket; and a belt around and asbestos tape made of thin steel and the spiral wound gasket. The ordinary rubber gasket for temperature lower than 120 DEG C; asbestos rubber gasket is suitable for steam temperature lower than 450 DEG C, the oil temperature is below 350 DEG C, the pressure is lower than the 5MPa of the occasion, for general corrosive medium, is the most commonly used acid asbestos board. In high-pressure equipment and piping, copper or aluminum, steel 10, stainless steel lens or other shapes of metal gasket. The contact width of the high pressure gasket and the sealing surface is very narrow (line contact), and the sealing surface and the gasket have higher processing finish. 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..

Q: There are 32; 3, 11/2, and so on, please master pointing, by the way, such tagging is based on what standards.: This is the American Standard. "6" means "DN150 11/4", which refers to "DN32", "11/2", "DN40", "" and "DN80"

Q: In the fire fighting pipeline, how is the flange piece quantity calculated?: 1, the valve flange: Sixth volumes of quota, valve, flange alone set quota, valves, flange bolts and other materials; when the set of eighth volumes, flange, bolt as auxiliary; I was in Liaoning, Liaoning also has seventh volume fixed valve, flange, bolts and auxiliary materials; if it is groove flange, direct replacement material or auxiliary line;2, pipe flange connection: flange containing in the pipe flange connection installed fixed, flange and bolt material of another; if there is no flange connection quota quota, should first set screw, and then set the installation of fixed flange;3, out of the pipe or interface pipe to leave the flange: sets of flange installation quota on the line; Liaoning sixth volumes and eighth books have flange installation quota;
