The data layer is molded or pressed into the top of the clear plastic layer. The data in the data layer is arranged in tracks that spiral like the grooves on a vinyl record (except CDs are read from the inside out, the opposite of vinyl records). 3. Now a reflective, metallic layer is located on top of the data layer. Categories of Welded Pipe and Their Use - LandeeGB/T3092-1993 ( galvanized welded steel pipe for low pressure fluid conveying). It is mainly used for conveying water, gas and heating hot water or steam, air, oil and other general low pressure fluid and pipe for other purposes. It is represented by material level Q235A steel. GB/T14291-1992 (welded steel pipe for mine fluid conveying).
For the pipes with the same sizes, types and length, the weight of ceramic pipe is about 1/2 of the wearable cast alloy steel pipe's, while the cost has reduced 10%~20% per meter. The weight of ceramic lined steel pipe is about 1/3 of the cast stone bent pipe's, 1/2 of the cast stone straight pipe's. Ceramic-lined carbon steel pipe, Ceramic lined pipeCeramic-lined steel pipe good resistance to mechanical shock resistance, while during transportation, installation and beat two weight bracket bent, not broken off the composite layer. Ceramic-lined carbon steel pipe with high wear resistance, anti-erosion ability of the fluid. Ceramic-lined carbon steel pipeJul 17, 2018 · The weight of the ceramic lined steel pipe is about 1/2 with the weight of the wear-resistant steel pipe or the double metal composite pipe. The construction cost is reduced by 30-40% per meter, and only the cast stone weight steel pipe is used. And rare wear resistant 2/5 around 20% per meter below the cost of the project.
