Q:in addition to the butter packing and graphite packing, and that kind of durability?Butter and graphite packing is not durable, 35 days is gone, looking for a durable alternative filler, can be used for 32 weeks is OK: It doesn't seem to be, or you use a muddy filling!! But for your consideration, you have to have graphite packing or butter packing!! Butter packing is better than graphite packing!!!

Q:What material flange gasket is better on the steam pipe?: Answer two: I think there is a problem of flange pressure rating is not high enough to design such as 150LB standard commonly used on soft flat gaskets, pressure rating of more than 300LB to recommend the use of metal winding pads I very strange, because the wound pad cheap?? Flange bolt torque low level is low and the corresponding metal winding pads need enough pressure to achieve the sealing effect, there is a low level of flange used to seal the torque, or not enough preload force is not up to the general effect of the former, or to recommend the use of inorganic fiber gasket, metal wound gasket......

Q:Now the general O ring is used moreNon-metallic, non asbestos gasket, paper gasket, rubber gasket, insulation gasket and so on.But I think they're all the same in shapeWho can tell me the difference between the sealing ring and the gasket? Use or something else, thank youI know they are all a general name, and what I want to know is how to distinguish themAnd there's the difference: As far as the distinction is concerned, from the model point of view, the O ring has a fixed model name. For example, 3.1*50., and gaskets have fixed models, such as oil seals, 45*60*7.

Q:What kind of gasket does flange have? What standard does it have?: Non metallic flat gaskets for HGT 20606-2009 steel pipe flanges (PN Series)

Q:Gasket free sealant: I don't know what you want to ask. Gasket free sealant is usually a room temperature curable one component silicone sealant.

Q:Why is copper gasket always leaking out of the sealing surface?: The sealing surface of two different material substances in contact is generally cast iron, cast iron due to the thermal expansion coefficient of copper with different period of time when the heating operation of the equipment, will not leak in a short time, but when the device stops again after operation will be oil leakage.

Q:What happens when the pressure on the gasket exceeds the maximum pressure?: Leakage is divided into flange leakage and blow out, the flat gasket will be blown out, winding gasket fracture and surface leakage!

Q:What's the difference between the gasket and the washer?: Other uses are used as spacers, springs (Baer, gasket, wave washer), wear-resistant pads, pre display devices, and locking devices. Rubber gaskets are also used on taps (valves) to cut off flowing liquids or gases. Rubber or silicone gaskets are also available to reduce vibration of the fan. Usually the outer diameter of the gasket is about two times the inside diameter.

Q:Is PTFE gasket poisonous to human body? Do I want to use it as a sealing ring in water cup?: A few years ago reported non stick pan, add inside a layer of Teflon (PTFE), at high temperature (180 degrees Celsius) when heated to a certain extent will release hydrogen fluoride gas, soluble in water to form hydrofluoric acid, it is toxic. But your cup pad can be assured.

Q:such as metal winding gasket, flexible graphite composite pad, metal gasket, asbestos pad and so on. 10Ask again, how much money does it cost to ask so many devices?: The metal pad 1500 a small winding machine, spot welding machine open graphite 500---4000 block, 1500----5500 block, composite pad double shear machine 5000 blocks, 1500 blocks of single shear machine, coating machine 8000 pieces about such a price, do the math.
