Cleaning method:
Open valve or desilting
Improved design of suction lines or desilting
Lower mounting height
1. Depth and Efficiency One of the most significant advantages of DTH rigs is their ability to drill to greater depths compared to conventional rotary drilling methods. They are capable of drilling depths exceeding 100 meters with great precision, which is essential in mining operations for reaching ore deposits.
02 REGULAR INSPECTION
Post-processing of large castings, large foundry processing manufacturers can use liquid sandblasting to clean the oxide scale and residue on the surface of the casting, which can not only remove impurities, but also play a role in polishing and improving the surface finish of the casting; Use grinding wheels, abrasive cloths, sandpaper and other abrasives to remove impurities such as burrs, protrusions and oxide scales on the surface of steel castings, so that the surface is smooth. In addition, methods such as mechanical, electrochemical and chemical polishing can further improve the gloss and corrosion resistance of castings.

Common sheet sizes for FRP grating include: 4’x8′, 4’x12′, and 3’x10′. Common thicknesses include: 1″, 1.5″ and 2″
At present, the joint laboratory’s first R&D project – on spray paint – free carbon fiber composite materials – has been officially launched. The product will be used first in new energy vehicles, not only to reduce the weight of the body, but also to significantly reduce the application cost of composite materials and improve production efficiency.
