Two 、 DB 42512-2008 flammable and explosive places lightning protection device and anti-static grounding device testing technical specifications6.2.2.2 oil and gas pipeline system6.2.2.2.1 inspection of long distance no branch pipeline and pipeline, in the process area (including production workshop, plant, storage tank, etc.), bifurcation should be set as required, grounding, testing its grounding resistance6.2.2.2.2 check the pipeline within the building 100m, should be ground once every 25m, test its grounding resistance6.2.2.2.3 check the parallel pipe spacing is less than 100mm, every 20 to 30m for electrical connection, when the pipe crossing and the net distance is less than 100mm, should be electrical connection, test its electrical connectionCheck the flange should be cross pipe connection, in the non corrosive environment of not less than 5 bolts can not cross the transition resistance testing flange bridging material specifications.

Q:Optical fiber telecommunications, but there is no place I want to position myself to buy white pigtail jumper modification to the living room TV wall. Now my idea is in the middle of the 2 flange butt joint SC, SC head of a white line connecting leader Telecom, a leader to the wall plug SC flange joint, I said because the total length of 50 meters and it would be enduring great??? The speed of the impact is not big?!!!! StopThe multimedia box SC box - Telecom - strong SC flange flange ----SC pigtailed light cat2 flanges! Wait for God online!!!!

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's the difference between a clip flange and a flange?

Flanged butterfly valves are flanged on the valve and bolted to both ends of the valve to connect the flanges to the pipe flanges. Sealing surface wear resistance, long service life. The utility model has the advantages of unique structure, flexible operation, labor saving, convenience, and high and low pressure without the pressure of the medium

Q:What's the price of a stack of 600 carbon steel flanges?

Sub threaded flange connection (threaded connection) flange and welding flange and flange clamp.The specification is cylindrical standards such as the standard book of mechanical department or the Ministry of chemical industry standard of American Standard the British standard on the subject are clear by the flange of the inner hole of the center distance of the thickness of the sealing surface size hole number aperture like so whether you use stainless steel or carbon steel for the production of flange specifications are the same.

Q:Flange German standard DIN, pleaseND16 what does that ND mean?It's ND in German standard DIN, not nominal diameter DN

ND refers to nominal diameter, approximate pipe internal reference dimension.Nominal diameter is not equal to outer diameter -2 times double thickness

Q:Flange WN50 (B) -25 RF S=6 specific points

WN indicates that butt welding 50 means nominal diameter DN (B means B series diameter is 57) - 25 is pressure, new standard is 25 kg pressure, old standard is 250 kg pressure RF, sealing surface protrusion S=6 flange diameter thickness is pipe thickness
