Untechnical production in Anshan Iron and Steel Company
A new year, and after the reform and transformation of thought, the pursuit of excellence quality development enterprises, Anshan all the staff together, through unremitting efforts, trenchless drill pipe has been achieved before the series production, which marks the EVI technical cooperation to carry out the factory again achieved important results, the Anshan Iron and steel seamless pipe the product has a broader space and efficiency.
As early as in May 2014, a project group was set up by the joint stock Development Department of Anshan Iron and steel company and Anshan Steel joint-stock seamless steel tube plant to develop the pipe for non excavation drilling rod. By the research group visited the market, with the cooperation of Hebei Province, two drill processing plants, through the combination of theory and practice, the design of a steel grade and chemical composition, to determine the process parameters of steel pipe, successfully developed meet user requirements of quenching and tempering heat treatment and pipe end thickening non excavation drill pipe.
It is learnt that trenchless technology refers to the construction technology of laying, replacing and repairing various underground pipelines, cables, wires and other public facilities by means of various geotechnical drilling and excavation equipments, such as directional drilling and directional drilling.
Trenchless technology originated in the 70s of last century and was introduced into China in the 90s of last century. It has been widely applied to new pipeline construction and old pipeline repair in the fields of water supply, drainage, electric power, communication, gas and so on. It can also be applied to cultural relics, ancient architecture protection and so on.
After the product is sent to the user, the processing performance is good. All the technical indexes meet the feedback of the design requirements of the trenchless drilling tools.
At present, the factory has trenchless drill pipe for different strength grade of pipe for a trial, the formation of pipe series products with the features of Angang No. 45, 27SiMn, 27SiMn-1, 28CrMoB, 28SiMnCr, 4130, AGZJ125 grade steel trenchless drill pipe, provides products and technical support to meet the different needs of the market.
Wonderful recommendation:
