- Q:Please describe it in your own words, not in the written language of Zou Zou.What's the flange?
- Flanges are connected to steel tubes in two ways: 1, threaded, and 2 welded.The flanges which are joined by welding are called welding flanges".The weld joint of flange and steel pipe is fillet weld. It is called angle welding".Flanges are pipe fittings"
- Q:What are the application technologies of welding flanges?
- Two. The welding flanges are usually made of forging or forging. When made of steel or shaped steel, the following requirements must be met:1, welding flange should be ultrasonic testing, no delamination defects; 2, should be rolled along the direction of steel cutting into strips, bent by welding into a ring, and make steel surface forming ring cylinder. The steel plate directly machined into the butt welding neck flange butt weld shall not;
- Q:DN200 how many screws are there in the weld flange?
- We want to know the welding flange of DN200. The 16 kg pressure is 12 screw holes. 10 kg pressure welding flanges are 8 screw holes. Welding flange in the field, all you need is a welding flange pressure of 16 kg, so we just get you 16 kilograms of welded flange welding flange connection, but in your site is not correct, your connection welding flange is 10 kg pressure. It also shows that the connection you purchased is also a 10 kg pressure welded flange. In accordance with the requirements of the pipeline, please change your connections at any time or change the pressure in the pipe.
- Q:What role does Sino French play in the waterproof casing pipe?
- Such as ventilation pipeline connection, the parts can be called "flange parts." but this is only a partial connection of a device, such as a connecting flange and a water pump, the pump is not called "flange type parts" relatively small. Such as valves, etc., can be called flange parts
- Q:What's the DN100 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.
- 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:How to set the bending coefficient of SolidWorks sheet metal base flange?
- The formula is as follows:L=0.5 pi * (R+K coefficient X T) * (theta /90)L: sheet metal unfolding length (Developed, length)R: inner radius at bend (Inner, radius)T: material thicknessBend angleY coefficient: a constant determined by the position of the Neurtal bend line, whose default value is 0.5 (the so-called "bend midline"). You can set its default value in config initial_bend_factorIn sheet metal design practice, the commonly used sheet metal flattening calculation formula is based on the K coefficient, the range is 0~1, which indicates the resistance of the material to be stretched when bending. The relationship with the Y coefficients followsY coefficient = (PI /2) * K coefficient
- Q:RJ what flange is the sealing surface?
- RJ is a form of flange sealing surface
- Q:How many kinds of flanges do you have? Does anyone know a more specialized classification?
- There are many kinds of flange, mainly due to the nominal diameter (A type B type, namely the metric system), nominal pressure, use of structure, material, sealing surface form, connection mode classification (diameter and pressure rating not included) according to the form of: flange welding plate flange (PL), hubbed flange (SO), neck flange (WN), integral flange (IF), socket welding flange, threaded flange (SW) (Th), welding ring flanges (PJ/PE), ring flanges (PJ/JR); according to the sealing surface form: process surface (RF), convex surface (MFM) and the tongue and groove face (TG), the whole plane (FF) and ring junction (RJ); this does not include the flange; according to the material: cast iron, cast steel, forging, flange, stainless steel flange, Q235 plastic flange etc..
- Q:Why use special flange for butterfly valve?
- The utility model has the advantages of quick opening and closing at 90 DEG rotation, simple operation, and good fluid control characteristics. When the butterfly valve is in the fully open position, the butterfly plate thickness is the only resistance when the medium passes through the valve body, so the pressure drop produced by the valve is very small, so the flow control characteristic is better.If the butterfly valve is used as a flow control, the main thing is to correctly select the size and type of valve. Butterfly valve structure and principle, especially suitable for making large-diameter valves. There are two kinds of butterfly valves commonly used: clip type butterfly valve and flanged butterfly valve. The clip type butterfly valve is a double headed bolt connecting the valve between the two pipe flanges.
