JST Successfully Developed Thickened Left-hand Thread Oil Pipe

On March 24th, JST Oil Pipe Department signed a contract of providing pipeline with Peru customer. They required the pipeline specification is 60.3×4.83mm N80Q EU 7000 feet and 73.02×5.51mm N80Q EU 8000 feet with left-hand thread.

Because the API standard takes the right-hand thread type, and JST never produce the left-hand thread oil pipe, so it is not only a new product for our company, but also an opportunity and challenge. JST leadership leads the technicians to take seriously study of this new kind of product and improvement the measuring implement and cutter equipment.

On May 12th, Peru customer appointed SGS to come to our company to check the products which are all qualified.
