Q:The middle tail of the total length of 50 meters and it would be great for enduring 2 flange head butt would like this?? Five
Fiber optic jumper transmission speed attenuation is greater, but also much smaller than the network transmission, 50 meters distance using two wins SC fiber flange, attenuation is only a few dB, ignored.
Q:What is the SO flange?
The chemical industry standard (HG) method: PL--, SO-- flange flange neck flange,WN-- butt welding flange......
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 does DN32 flange mean?
DN is nominal size 32 means 1-1/4, not internal diameter 32mm
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: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.
Q:How should we get to know the flange?
Flange forging forging casting iron and casting into a two GB standard and non standard to distinguish various standards, including some foreign standards.Such knowledge is not to be taught, but to be learned
Q:What are the specifications of orifice flanges? Be comprehensive
Appendix A of national standard HG 20592-2009 is marked with only WN (high neck welding flange)Pressure rating PN10~PN160Beside the flow hole socket welding or NPT mouth NPS 15 bearingASME B16.36-2009 American Standard marked WN (high neck flange) and SO (neck flange) twoPressure level 300LB~2500LB no 150LBBeside the flow hole for the 1/2 "NPT age
Q:How many kinds of flanges are there?
4. according to the material for making flangesAccording to the flange material can be divided into: cast iron flange, steel flange, plastic flange, copper flange and so on.At the same time, there are 4 standards for flanges in our country, namely, versatility and specificity. Each flange standard is not limited to the scope of this trade, but it is crossed and permeated. In order to gradually unify the flange standard, the National Machinery Committee has formulated a series of flange standard, where GB/T9112~9124 - 2000 "steel pipe flange" series standard is quite comprehensive, but this does not mean the national standard to replace the other flange standard. HG/T20592~20635 - 2009 "steel pipe flanges, gaskets and fasteners" is adjusted and revised based on the original HG/T20592~20635 - 1997, which is set by European and American system system respectively in the preparation of pipe flange standard system, clear and operational use.
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..
