Company's existing five spiral steel pipe production line, can produce Φ 219 - Φ 2320 mm, wall thickness 6-25.4 mm, the highest grade of steel for X80 seam submerged arc tube, comprehensive 200000 tons, mainly used in oil, gas, water, gas and other high voltage long distance pipeline.


CSPG is committed to oil and gas field development and urban public facilities construction, and strive to create a harmonious energy and environment.The company will be excellent technology, first-class products and dedicated service, and friends at home and abroad to work together to create a grand cause.


Also called spiral cylinder or spiral body.The outer diameter of the spiral tube is about 30 nanometers, the inner diameter is about 10 nanometers, and the spacing between adjacent spiral tubes is about 11 nanometers.Each week of the helix tube is surrounded by 6 nucleosomes. The H1 histone protein is located on the inner surface of the helix tube cavity and plays an important role in maintaining the structure of the helix tube.The 10-nanometer fiber composed of nucleosome spiraled to form a 30-nanometer thick fiber, which further compressed the length of DNA by 6 times.
