Mica tube insulation classification

There are many types of mica pipes. Different categories have different uses. I will briefly introduce the categories and uses of several types of mica pipes for everyone:
1. The 5931-2 shellac mica tube is glued into a tube blank using mica flakes and shellac.
2. The 5932-2 epoxy mica tube is made of mica sheet and epoxy resin glued into tube blanks.
3, 5933-2 shellac mica pipe is glued with mica and shellac paint E-glass cloth
The above are all made by hot rolling. The mica tube is suitable for the insulation of the motor outlet sleeve.
The surface of the mica tube should be smooth and free of delamination, and must not contain impurities or gaps. The inner wall is allowed to have slight creases, and both ends should be cut cleanly, but the end slope must not exceed half of the length tolerance.

NM Steel Plate

Besides NM Steel Plate, HP Wear Resistant Group offers various products of wear plates namely Cr-Carbide Weld Clad Plates, Smooth Surface CCO plate, Heat Treated Wear Plates (AR Plate or Q&T Steel), Casting Plates, Tungsten Carbide Coated Plates in various grade and multiple size options.


An abrasion resistant, quenched and tempered, high strength, fine grained steel Wear Plate and Abrasion Resistant Wear Plate offers lower cost wear protection. With a hardness of 250 to 320 BHN, it will outlast hot rolled carbon plate but can still be drilled, punched, or machined for liners and wear plates. Strength characteristics of this plate make it an excellent choice for structural use.


Provides superior hardness to toughness ratio. NM Steel Plate is liquid-quenched and tempered and through-hardened. The result is a plate with excellent abrasion resistance and high impact resistance. The outstanding wear characteristics can be attributed to the balanced chemistry and very fine distribution of Chromium, Boron, Titanium and Molybdenum. The resulting carbides reinforce the plate structure and provide uniform through-hardness.


Provides maximum wear resistance from impact and sliding. The fine grained, thru-hardened alloy steel chemistry makes this plate have the optimum hardness/toughness ratio.
