Q:Introduction of flange
Flanges (Flange), also called flanges, flanges, or flanges. A flange is a part that is connected between the pipe and the pipe, used for the connection between the ends of the pipe. It is also used for the flange on the entrance and exit of the equipment. It is used for the connection between the two devices, such as the reducer flange. Flange connection or flange joint means that the flange, the shim and the bolt are mutually connected as a group of three detachable sealing structures.
Q:What are the common materials and grades of aluminum alloy flanges?
The aluminum alloy flange is a connecting part between the pipe and the pipe, used for the connection between the ends of the pipe. It is also used in the flange of the equipment entrance and exit. It is used for the connection between the two equipments, such as the reducer flange. Flange connection or flange joint means that the flange, the shim and the bolt are mutually connected as a group of three detachable sealing structures.
Q:What is flange? Why is it called flange?
Reducer flange for motor and reducer connection, as well as reducer and other equipment between the connection.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 mechanical (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:How did the magic baby get into the North Garden of the flange?
Go out of the west gate, down the road. Between the two mountains, OK!
Q:Do I need flanges for rubber joints?
There are two carbon steel flanges at both ends of the product,Some customers also need counter flanges.
Q:What's the thickness tolerance of neck flange?
Specification for JB/T74-1994 pipe flangesSH3406-1996 steel pipe flanges for petrochemical industrySpecification for GB/T17241.7-1998 cast iron pipe flanges
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: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.
