4. USS Tubular Products The Beginning
1869- John & Harvey Flagler build a 20 x 125 ft. lapweld pipe mill in Boston, MA - primarily produced boiler tubes
1870- National Tube Works Company is created and moved to the center of the iron and steel industry- Pittsburgh, PA
1895- First seamless tube is produced to be used to construct bicycle frames
1899- National Tube Works is consolidated with other pipe manufacturers to form the National Tube Company
1901- USS acquires National Tube Company (NTC)
Post Automobile demand increased creating a demand for higher quality steel tubing- Secondly, the rapid increase in auto production created a demand for gasoline
1914- NTC produces first seamless steel drill pipe in the oil industry followed shortly by the development of the first seamless steel couplings

5. USS Tubular Products
National Tube Company
Comprised of multiple steel making facilities as well as tubular manufactures
Installed the first integrated pipe mill in the U.S.
Installed the first seamless tube mill in the U.S.
Developed the double piercing process and the rotary rolling process which extended the commercial size range of seamless pipe from 8” to 26” O.D.
At one time owned the largest pipe mill in the world

Lorain Pipe Mills
1894 Broke ground as the Johnson Company and later became part of U. S. Steel Corporation in 1901.
1904 becomes part of National Tube Company
1930 #3 Seamless begins production
1943 Lorain supplies 1,254 miles of 24 inch diameter pipe for the “Big Inch” pipe line, which brought oil from Texas to the East coast during World War II.
1948 #4 Seamless begins production as world’s first continuous seamless pipe mill
1932 #2 Seamless begins production
1984 #2 Seamless shut down due to new Fairfield Pipe Mill
1962 Continuous Weld Mill opens
1965 ERW Mill opens
Christy Parks Work
Closed Facilities

8. Capable of producing pipe from 4 ½”-16” diameter & 20”-40” diameter
Christy Parks Works
Established in 1897 in Mckeesport, PA
First named the United States Seamless Tube Works, but at the turn of the 20th century became part of the National Tube Company
Made an integral part of U.S. Steel in 1964 under the name Christy Park
Main production consists of seamless pressure vessels
Produced over 10,000,000 pieces of weapons and munitions during the Korean War
Produced projectiles for the U.S. troops fighting in Cuba during the Spanish War
Provided 5 ½ million shell forgings and projectiles during WWI
Produced bomb lines during the Viet Nam War
Sold to CP industries in 1986
Texas Works – Baytown
Construction in Baytown, TX began in 1967 and took more than 1400 people four years to build initial plant
Pipe mill added as an extension to plate mill in 1978
Pipe mill was the first domestic source capable of producing 48” diameter pipe
Pipe was made using the U-O process
Pipe mill was constructed to supply line pipe for the transportation of oil and gas
Closed in 1987
Geneva
Steel mill was constructed with federal funds in 1941 to insure the nation’s steel industry would be able to meet the increased demand for steel by both military and industrial users
Plant was located in Utah far inland as a precaution against steel shortages in the West in case of a Pacific Coast invasion during WWII
U.S. Steel purchased Geneva from the government in 1946 for $47.5 million with an estimated value of $144 million
Pipe mill installed in 1954 to take advantage of demand for large diameter pipe in the West and the growing market for smaller diameter pipe
Integrated with a ready supply of plate and coil products being produced at Geneva
Small diameter pipe was electrical resistance welded. Large diameter pipe was produced through submerged-arc welding using the U-O- process
Capable of producing pipe from 4 ½”-16” diameter & 20”-40” diameter
Marketed 80’ sections of double-jointed large diameter pipe for the energy sector
Gary Tube Works
Originally planned in 1916 to supply welded pipe & casing
Located in Gary, Indiana and began operations in 1926 producing lap weld and butt weld pipe
Constructed a seamless mill in 1931, but all production was stopped that same year
The plant was reactivated in to manufacture alloy tubing for defense equipment
USS Tubing Specialties was organized in 1976 as a separate operation to combine sales efforts between Gary, Christy Park, and Lorain Works
Fairless Pipe Mills
Originally installed at Fairless Works in Fairless Hills near Philadelphia, PA in 1953
Consisted of one skelp mill and two continuous weld mills capable of producing black and galvanized pipe 2.375” to 4.5” diameter
Included complete facilities for pipe finishing including facing, threading, coupling, hydrostatic testing, galvanizing, coating, stenciling, and bundling
Pipe mill was closed in 1991

This is a detailed view of U. S. Steel Tubular Products – Facilities shown here in white text. The blue dots indicate pipe producing facilities and the red dots are for sales offices and finishing operations. In gray are our flat roll facilities.
With headquarters located in Dallas, we have sales offices in Houston, Pittsburgh, Bakersfield and Calgary. In addition, various JV’s and alliances provide our Tubular group with a presence in the global market.
We produce the full range of API and ASTM products at all our facilities, including a number of specialty tubing products such as hydraulic cylinders, trailer axles, high pressure cylinder stock and other mechanical applications.
Immediately following the acquisition, one of our top priorities was to realign relationships with selected distributors. As a result of this realignment, we have established an efficient supply chain network committed to maintaining short lead times with consistent reliable deliveries.
We also quickly migrated best production practices across all of our tubular operations, with a common focus on being leaders in safety, housekeeping, environmental performance, quality, efficiency, and customer service.
