Shandong Sheng Machinery Co., Ltd. has many years of sub-cement pipe and cement pipe mold manufacturing experience, in recent years, developed a variety of pre-cement products processing equipment and building materials machinery and equipment.

     "Cement pipe machine equipment" generally includes "hanging roller technology", "centrifuge technology", "core mode vibration technology", "vertical vibration technology", no matter what kind of process, the raw materials are included:

1, cement

Should use numbered 425 ordinary portland cement (425R). Since hanging roller tube using dry concrete. Mix water-cement ratio is small. Small changes in the volume of the shrinkage of cement. Due to the amount of cement to unilaterally is not high. So generally does not appear shrinkage cracks. Since the initial setting time of cement is relatively short. High early strength. For concrete stable compactness \ prevent the inner wall of the slump, improve steam curing good.

2, sand

Commonly used in sand, concrete workability, good impermeability, and low concrete strength, pipe easily collapse; coarse sand, concrete workability is poor, good impermeability, and high intensity mixing, system the tube is not easy to collapse, select sand ratio is also very important, high sand, concrete workability good formability, good impermeability, while the concrete pipe is easy to collapse; sand is low, concrete workability poor, poor shape, poor impermeability, and easy to pipe in concrete slump.

3, gravel

Small diameter suspended roller tube with pebbles or crushed gravel, gravel surface to reduce friction, easy compacting the concrete molding, large diameter pipe should be used hanging roller crusher stone, easy to use gravel surface roughness characteristics of each embedded solid to relieve concrete slump possible.

      Shandong Sheng Machinery Co., Ltd has been committed cement products machinery research and development, production and sales, with advanced equipment, professional and technical skills, and two decades of practical experience, the company has always been at the forefront of research and development center block making machine market development , concerned about the advanced technology at home and abroad, to develop products for the investment needs of different users, there are block making machine, hydraulic tile machine, cement pipe machine, blender, suspended roller machine, wire rod machine equipment. Currently has 19 branch offices and six foreign countries (Nigeria, Tanzania, Algeria, Kenya, Mozambique, Ethiopia) and exported more than 100 countries and regions.
