T.U.F.-PIPE for OCTG
Nippon Steel Corporation, the world’s largest steelmaker,
supplies a full range of pipe and tubes — 1.5 million ton a
year. Oil companies and other energy-related firms around
the world have come to regard Nippon Steel as the standard
of quality for these products.
Quality has improved over the years to the extent that
defect-free weld metal, which are tough as base metal, are
consistently achieved, making Nippon Steel’s ERW pipe
ideal for OCTG applications. In fact, it is so superior to
conventional ERW pipe that a new name is needed. This
catalog will show why this new pipe, T.U.F.-PIPE, can satisfy
all your requirements for quality, quantity and delivery.
Characteristics
Superior MaterialNippon Steel production system begins with advanced metallurgy
and clean BOF steelmaking practices. Continuous casting followed
by hot-rolling, produces hot-rolled strip of optimum quality for pipe
making.
High Dimensional AccuracyHigh uniform wall thickness and smooth finish free from nonmetallic
inclusions and surface defects provide casing and tubing with a
superior level of quality and excellent driftability as well as high per-
formance properties.
Tough WeldWeld metal free from defects and as tough as the base metal result
from Nippon Steel’s newly-developed technology.
High Performance PropertiesNippon Steel’s proprietary standard “NT-Series” have higher perfor-
mance ratings than corresponding API grades.
Wide Range of AvailabilityT.U.F.-Pipe is available in outside diameter from 4.5 in to 20 inch,
wall thickness up to 0.750 in and length up to 65 feet.
Tough materials, Uniform properties, Free from defects

TG q Steelmaking
Degassing and desulfurizing of the metal during the steel-making process produce clean steel with low non-metalic inclusions and better surface finishes. w Hot RollingAdvanced hot rolling results in hot coil with a fine grain structure and high dimensional accuracy. e Spiral LooperThe spiral looper supplies a steady feed of coil down-stream to the continuous edge milling, pipe forming and welding stands.
r Forming StandsHeavy duty stands accurately form the incoming coil into pipe having a wide range of wall thickness and outside diameters. t PWP HF-WelderThe Perfect Welding Process, developed by Nippon Steel, produces high quality welds. Seams are inspected by ultrasonic testing. y Welded Seam Heat TreatmentHeat treatment in the welded zone stabilizes the micro-structure and gives it the same physical properties as the base metal. The exact seam position is determined by optical sensors for seam heat treatment, and ultrasonic and hydrostatic testing. u Non-destructive TestingEvery length and all surfaces of each T.U.F.-Pipe is sub-jected to a full line-up of non-destructive tests. i Automatic InspectionEvery pipe is given a comprehensive check using automat-ic inspection equipment. o Monitoring and Tracking SystemT.U.F.-Pipe is monitored and tracked at every stage of pro-duction by on-line computers. All manufacturing data is stored by computer and can be made available in any form required by the customer. !0 MarkingAutomatic stencilling and die-stamping machines identify and clearly mark every pipe.
!1 Thread CuttingAdvanced NC lathes cut high precision threads to order. Connectors for large O.D. casings are also available. The use of thread protectors is recommended to prevent damage to the connectors during handling, loading and pipe rolling.

1. Welding conditions are not always the sameVarying combinations of welding heat input, welding speed, pipe wall thickness and the like produce different weld results.
2. Optimum welding conditions form a narrow range.Low heat input causes undesirable cold welds. High heat input leads to so-called penetrators. A sound weld thus requires control of heat input within a relatively narrow range.
The three combined Non-destructive Inspection System, Automatic Measuring and Inspection System, and On-line Monitoring and Tracking System together represent a thorough battery of tests that will satisfy every customer’s requirements. Each pipe undergoes this examination.
1. Non-destructive Inspection SystemThe NDI checks not only the whole pipe body, but also the weld seam and pipe-ends.
2. Automatic Measuring and Inspection SystemThe outside diameter, roundness and straightness, as well as the length, weight and wall thickness of every pipe are checked and recorded automtically.
3. On-line Monitoring and Tracking SystemAn on-line computer monitors and tracks each pipe at every step of the pipe-making process. This inspection data is collected and stored to assure the quality of each product.
3. The System monitors and controls welding conditions at every instant.
With this system, welding conditions are controlled within the optimun range and the operator is clearly aware of state of welding.
