Wear Rubber Lined Pipe
Wear Rubber Lined Pipe From JinRuiDa Industry Solutions Co.,Ltd. One good rubber lined pipe manufacturer need a complete system including of raw materials, processing, testing equipment, manufacturers.
Rubber Lined Pipe Process:
Wear Rubber Lined Pipe Steel Skeleton Frame Sand Blasting : Sand Blasting On The Inner Wall Of The Steel Skeleton Frame Required By The Rubber Lined Pipe To Ensure The Steel Pipe Skeleton Frame Inner Wall Is Clean. Make The Inner Surface Roughness Of The Steel Pipe Skeleton Frame Reaches 45~75 Microns.
Wear Rubber Lined Pipe Surface Degreasing : Put The Steel Pipe Skeleton Frame On The Work Table, Apply The Oxalic Acid Solution To The Surface Of Steel Pipe Skeleton Frame That Need To Be Rubber Lined.
Rubber Lined Pipe Apply Adhesive On Surface & inside : After Surface Degreasing 5~10 Minutes, Apply Adhesive A, After Make Sure Adhesive A Be Dry, Apply Adhesive B.
Rubber Lined Pipe Making Rubber Lining : Preheat Rubber Materials, Use Rubber Extruder Finished The Rubber Lined.
Rubber Lined Pipe Steel Pipe Rubber Lining : Use Oxalic Acid To Clean Surface Of Rubber Lined, After Rubber Lined Surface Dry, Apply Adhesive On The Surface.
Rubber Lined Pipe Vulcanization : Put The Rubber Lined Pipe Into The Vulcanization Tank. After Rubber Lined Pipe Vulcanization Finished.
Rubber Lined Pipe Inspection : Test All Adhesive Surfaces By High Voltage Spark Tester. Make Sure All The Rubber Lined With Steel Pipe Skeleton Frame Are Well Bonded And There Is No Missing Place.

Generally do not have rubber production capacity and testing equipment for the Rubber Lined Steel Pipe. So it is difficult to guarantee quality of rubber lined pipe, the thickness of rubber as it directly affects the performance of the use of rubber lined pipe, so in the choice of manufacturers, must choose a certain technical ability of manufacturers in recent years, although the domestic market of rubber lined pipe manufacturers a lot, but because they do not have a complete set of production, inspection and management system, the product will cause bad consequences of such as power plant an important sector, so be sure to choose have the technical ability of the production enterprises.

No.5, Characteristics of Rubber Lined Pipe
Rubber Lined Pipe with long-life wear rubber with smooth walls and low flow resistance. Together with couplings and gaskets, these pipes form an extremely reliable system which retains the free flow area without turbulence at the couplings.
No.6, Technical description of Rubber Lined Pipe
High strength Rubber Lined Pipe with natural rubber.Steel surfaces are painted gray. The safety factor is 1.5 times the working pressure.
No.7, Installation of Rubber Lined Pipe
Wear Resistant Rubber Lined Steel Pipe Reducer have fixed lengths and are designed to be used together with Couplings and Gaskets on straight sections as an complement to Material Handling Hose.
