Is the gasket sealed at the pressure gauge connection?
Gaskets must be added to the pressure gauge joint.The pressure gauge has a lot of material, but the most used in stainless steel, there are some pressure gauge interface material of copper alloy, mainly bronze (copper and tin alloy) and brass (copper zinc alloy), copper (copper nickel alloy).The spring tube of the ordinary pressure gauge is mostly made of copper alloy (high pressure alloy steel), but the material of ammonia pressure gauge and spring tube is made of carbon steel (or stainless steel), and copper alloy is not allowed. Since ammonia produces chemical reactions with copper, it will explode, so ordinary pressure gauges cannot be used for ammonia pressure measurements.
Encryption pads are required, as well as encrypted sealing rings or raw tape.The rubber gasket is a self expanding sealing gasket, belonging to the sealing component of the pipeline. The gasket is composed of an outer ring, the middle ring and the inner ring expansion of three parts; the outer ring and the inner ring is generally elastic sealing ring, the middle ring at the center of a ring on both sides of the bubble structure, hollow ring, outer ring seal ring outer ring and the inner side of the opening; the inner ring is divided into two parts installed in the middle, inside and outside the ring structure of the global expansion.Rubber gasket is also very extensive use, we usually drink drink cover, there are a layer of rubber pad, that is used to seal the use of this to isolate the flow of air from the outside. The working principle of the machine is static and dynamic. In short, are used to carry out isolation from the outside world or a place, the work principle of the gasket is also very simple, it can be said that there is no too many principles, that is, isolation.
Hello, I am specializing in instrument production and sales!For your question! I can tell you very, very definitely! No matter what the thread connection table, you need to encrypt the seal! Only some encryption seal pad; some encryption sealing ring; some with raw meal belt!I don't know what thread it is! Then I can tell you whether to add a mat or a raw meal belt!
