What are the styles of straight through mirrors

What are the styles of straight-through mirrors:

1. According to the materials.

Stainless steel is divided into martensitic steel, ferrite steel, austenitic steel, austenitic-ferrite (biphasic) stainless steel and precipitated hardened stainless steel. Stainless steel is commonly used in austenitic stainless steel. This type of steel has good plasticity and toughness, weldability and corrosion resistance, corrosion resistance in oxidizing and reducing medium are good, used to produce acid stainless steel sight glasses, more common with 304 stainless steel mirror, 316 stainless steel sight glasses, 316 L stainless steel mirrors, other such as 201301304 L, 321 material such as stainless steel glass is rare.

According to the purpose.

Inside the stainless steel mirror on the tube with the stainless steel pipe mirror, stainless steel direct mirror, stainless steel impeller mirror, stainless steel float ball mirror, stainless steel glass tube mirror.

Also used in the container equipment flange mirror, stainless steel pressure vessel mirror, with a neck mirror, stainless steel lamp mirror.

Three. According to the connection mode.

There was originally only one way to connect the container to the stainless steel mirror on the device, which was welded to the container with or without a neck, but a flanged clamp was added to the doe standard.

And on the stainless steel pipe connection is much, flange, (such as stainless steel flange straight sight glasses), thread (internal thread glass tube stainless steel cup) is a common way of connection, another common welding (welding straight sight glasses), fast (fast loading glass cup), the clip (lens) to the clamp, hose connectors, etc.
