UO Pipe Forming, Welding and Finishing Steps Preliminary to Forming Forming Plate into Circular Shape Tab Plate Affixing A tab plate is precisely affixed to each corner of the plate for pipe by means of a dedicated MAG welding robot to permit quality welding beyond the pipe ends. “UO Forming” The edge-planed plate is automatically fed through the crimping press, U-ing press and O-ing press and is deformed into the shape of an almost closed circle which is then ready for welding Edge Preparation Shaving tools or milling cutter accurately machines both longitudinal edges of the plate, producing...

UO Pipe Inspection and Testing Welding Image of outside welding Configuration of Automatic Welding(Inside) System Inside and Outside Welding The tack welded pipe is welded on the inside and outside by the multi-electrode SAW method. The SAW machine used in this operation is capable of performing all welding operations automatically from receipt of the tack welded pipe and the seam alignment to delivery of the welded pipe. It also has many other features including a welding condition controller which can accurately control the welding process parameters to preset values. All these add up to highly...

Nondestructive Examinations All pipes are subjected to a series of stringent nondestructive examinations such as ultrasonic testing, X-ray radiography, X-ray fluoroscopy (KIMITSU only) and magnetic particle testing. NDEs are carried out by qualified inspectors. X-ray Fluoroscopy [KIMITSU only] The X-ray fluoroscopic examination system consists of a small focus, high performance X-ray tube and special dynamic image processor and offers highly sensitive pictures. Automatic plate UST The entire surface of each plate is scanned by multi-channel UST with a self sensitivity assurance system and a self-calibration...

Physical Testing Computer System for Quality and Production Control In addition to in-line testing, random samples of pipe are subjected to a rigorous program of off-line testing for mechanical properties of base metal and weld metal. In some case, HIC resistance and fracture properties are checked by using actual pipe. These comprehensive testing procedures assure users of highest quality products that conform to exceed the specification. Tracking System Data Collation Between Plate Mill and Pipe Mill: It is possible to completely eliminate the risk of unwanted plates entering the UO pipe mill...

Coating External Polyethylene Coating Polyethylene Adhesive Primer(organic and/or inorganic) Internal Coating The external polyethylene coating of UO pipe is applied by extrusion of polyethylene resins using T-dies. NSSMC started production of polyethylene-coating UO pipe in 1974, the first example in Japan. Since then, polyethylene coated large-diameter pipe has been finding widening application as oil and natural gas line pipe and is today highly reputed among third-party institutions. Internal-coating UO pipe is also available from NSSMC. This type of UO pipe is enjoying welding acceptance...

SIZE RANGE OF UO PIPE NSSMC UO pipe mills produces pipe with outside diameters from 18 inch to 60 inch. The equipment to produce such pipes reflects NSSMC’s intent to meet the great demand for larger and heavier steel pipe. Wall Thickness Submarine pipelines require pipe of greater strength and toughness. To produce pipe with wall thickness up to 1.57inch. NSSMC has installed very large crimping press, U-ing press and expander. Pipe Wedge Length NSSMC UO pipe mill can produce pipes with lengths up to 60feet. The long pipes reduce the number of weld joints and inspections necessary at the site,...
