The company specializes in the research and development, production and sales of RINA grade D stern frame steel seamless pipes, longitudinally welded pipes, large-diameter welded pipes, API 5L welded pipes, spiral welded pipes, and large-diameter thick-walled straight seam steel pipes. The company has RINA grade D stern frame steel five production lines in three major production workshops: large-diameter longitudinally welded pipe production workshop,RINA grade D stern frame steel rolled steel pipe production workshop, and thermally expanded steel pipe production workshop, with an annual production capacity of more than 100,000 tons.
In addition to our own truck fleet, we also have long-term cooperation with certain logistics companies to ensure that we can deliver RINA grade D stern frame steel goods in time and smoothly. At the same time, because of the long-term cooperation and huge shipping volume, we can get a good transportation price and save transportation cost for the company and customers. Meanwhile, we have Shipping Department to arrange shipping work in advance. So as not to waste time on transportation both in land and on the sea.
Non-destructive flaw detection of steel plates is a test method for inspecting the RINA grade D stern frame steel surface and internal quality of the inspected parts without damaging the working state of the workpiece or raw materials. Commonly used RINA grade D stern frame steel steel plate flaw detection methods include: X-ray flaw detection, ultrasonic flaw detection, magnetic particle flaw detection, penetration flaw detection, eddy current flaw detection, gamma-ray flaw detection, fluorescent flaw detection, color flaw detection and other methods. Physical flaw detection is non-destructive flaw detection without any chemical changes.
In December of 2015, our regular India customer sent us an inquiry for RINA grade D stern frame steel pipe. The inquiry requires no negative tolerance in both pipes’ outer diameter and pipe wall. After two weeks’ discussion, he put the order of 275 tons to us. The pipes are finished within just one month. Our customer come to our factory to inspect the quality and tolerance, all the products are well meet his demand. The pipes are arriving to Nhava Sheva port, customer is very happy with our products and service during the process.
