Q:Magic Baby how to enter in the hall in the flange
When entering the hall to look at the sun and moon, two when no hall opened the door
Q:What's the DN100 flange?
Reducer flange for motor and reducer connection, as well as reducer and other equipment between the connection.Sort:1, according to the chemical industry standard (HG): integral flange (IF), (Th), threaded flange welding plate flange (PL), neck flange (WN), hubbed flange (SO), socket welding flange, butt welding (SW) ring loose flange (PJ/SE), flat loose flange ring lining flange (PJ/RJ), (BL (S)), flange (BL). 2, according to the petrochemical industry standard (SH): (PT), threaded flange welding flange flange (WN), (SO), socket welding flange (SW), loose flange, flange cover (LJ) (not note). 3, according to the machinery (JB) industry standard: integral flange, welded flange, welding plate flange, butt welding ring loose plate flange, welding ring loose plate flange, flange ring loose plate flange, flange cover. 4, according to the national standard (GB): integral flange, threaded flange, flange, butt welding and hubbed flange hubbed socket welding flange, butt welding neck flanges, ring plate flange, butt welding ring loose plate flange, welding ring loose plate flange, flange ring loose plate flange flange cover.
Q:What are the application technologies of welding flanges?
First, the level of welding flanges and their technical requirements shall comply with the corresponding requirements of JB4726-4728. 1, nominal pressure PN for 0.25MP-1.0MPa carbon steel, austenitic stainless steel forgings, allowing the use of grade I forgings. 2, in addition to the following provisions, the nominal pressure of PN 1.6MPa-6.3MPa forgings shall meet the requirements of secondary or secondary forgings. 3, in line with one of the following conditions, and shall comply with the requirements of forging III: (1) PN = 10.0MPa nominal pressure flange forgings; (2) the nominal pressure PN>4.0MPa chrome molybdenum steel forgings; (3) PN>1.6MPa nominal pressure and the working temperature is less than or equal to -20 degrees Celsius ferritic steel forgings.
Q:How many bolt holes and how big bolts are there in all sizes of 16 kg flanges?
You said this decision can be empty and bolt by bolt much, because the flange 16 kilograms he represents not only much, such as to the decision of the 59 flange bolts and how much air is generally 59 bolts, flange 4 bolt space using 14 bolts, 59. All 4 bolts empty more than 59 is still some 4 empty, there is 8 according to the size of the flange bolt empty it is not the same, and the use of bolts are based on flange to determine the size of the bolt can also use a smaller, bolt general equipment use 4.8 hardness the special equipment used is 8.8 bolt hardness, 16 pound flange generally use 4.8 hardness
Q:What is the SO flange?
SEO hubbed flange see below: welding flange diameter steel tube inserted in. The part of the weld where the flange protrudes. Here is the sealing surface
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;
Q:The connection between the air outlet and the air duct can straddle the flange
Can not.The air outlet must be connected directly to the air duct. If the size of the air outlet is larger than the length of the air duct, a suitable length of air duct must be made to facilitate the connection of the air inlet.
Q:Flange "WN100 (B) -16RF S=6" and "SO50 (B) -16RF", "PL200 (B) -16RF" represent what kind of flange,
According to your model, it should be the chemical department HG20592-2009, this is the latest version of the implementation standards, you first look for it
Q:Can the aluminum flange 6061 and the aluminum tube 6063 be welded directly? Will there be such a fracture?
1, welding can be no problem.2, as long as the welding process is fine.
Q:What do butt welding flanges WN300-150, RF, Sch40 mean?
WN said neck flange; 300 said flange nominal diameter DN300 welding diameter of 325MM, the 150 refers to the nominal pressure flange is 150LB (pounds) system will usually only America in pounds nominal pressure; RF said flange sealing surface for ordinary raised face seal, SCH40 said steel tube wall thickness, the thickness is 10.31MM general welding neck flange with ring loose flange complete specifications are required to fill in the pipe wall thickness.
