Advantages of using pipe jacking method

The advantages of the pipe jacking method are the advantages of the pipe jacking method. In addition to the high control precision, the pipe jacking method has the following advantages:

(1) Pipes can be laid deep underground.

(2) The interference to traffic is small, and there is no need to cut off traffic.

(3) You can cross obstacles.

(4) Construction noise and vibration are very small.

(5) The impact on the surrounding area of ​​the construction area is small.

(6) It is safe to cross roads and railways.

(7) Construction in urban areas If the groundwater is not very rich, and the pipeline is buried shallow, the economy is better.

Production Introduction

      Silicon Carbide  fine powder is a type of the silicon carbide, which has Silicon Carbide Sand and silicon carbide particle size. According to different sizes to devide different mesh. The size generally divided into 8 # -320 #, the larger the model, the finer the particle size. Generally referred the size than 320 # as Silicon Carbide Powder. Silicon carbide particle size sand is divided into black and green two kinds, which are the ideal abrasive, mainly used for polishing, making grinding wheel, cutting sheet and other abrasive industry.

Black and Green Silicon Carbide has high purity, hardness characteristics. It mainly used in abrasive, refractory and electronic industries. The particle size has 0-10mm, 0-20mm, 0-50mm, 1-3mm, 3-5mm, 5-8mm, 1-10mm and so on.


    The silicon carbide with high hardness, chemical stability and toughness characteristics, so silicon carbide mainly used to manufacture bonded abrasive, coated abrasive and free grinding. Using this raw materials to process the glass, ceramics, stone, Cast iron and some non-ferrous metals, hard alloys, titanium, high-speed steel cutting tools and grinding wheels.

Each Grain size and packaging can be processed according to customer`s requirements.
