HDT controls the entire manufacturing process from raw material to finished products, Inspection points are localed in the manufacturing process to ensure all products meet all requirements. In such quality control system, faults are detected at the earliest possible stage of the production process in order to eliminate the risk of rejection at final inspection. We have made continuous efforts to reduce the problem throughout total quality assurance system including traceability control, HDT not only inspect by ourself , also through TPI like BV, SGS, DNV, ABS, MOODY, IBR, so that today the quality of our productsis clearly recognized by our client.
HDT supply huge qty of Cr-Mo Alloy seamless pipes and tubes , and export more than 37 countries . Our alloy seamless tube be width used in boiler and heating. We can help clients to bend pipe as they requests.
Carbon steel pipe can be divided into seamless steel pipe, straight steel pipe, spiral steel pipe, high frequency welded steel pipe and so on.Carbon steel seamless steel pipe is a kind of long steel.
The pipe has a hollow section and is used in a large number of pipelines for fluid transportation, such as those for oil, natural gas, gas, water and some solid materials.
Generally, the outer diameter of hot-rolled seamless pipe is greater than 32mm, the wall thickness is 2.5-75mm, the outer diameter of cold-rolled seamless pipe can be up to 6mm, the wall thickness can be up to 0.25mm, and the outer diameter of thin-walled pipe can be up to 5mm, the wall thickness is less than 0.25mm, and the precision of cold rolling is higher than that of hot rolling.
