Geological tube is steel pipe that using core drilling for the geological department, which a hollow cross section, surrounded by long geological drilling joints with steel pipes. Stainless steel can withstand corrosive or chemical environments due to its smooth surface. To further the long performance life of steel pipe, Northwest Pipe offers both dielectric and chemical inhibitor pipe coatings such as polyurethane and tape. Northwest Pipe leads the industry in joint technology and scientific analysis to construct joints that maintain integrity for the service life of your project. Welded Pipe American Piping distributes an extensive selection of welded pipe, including Electric Resistance Welded (ERW) and Double Submerged Arc Welded (DSAW) carbon steel pipe — along with their respective flanges and fittings.

Welded steel pipe (steel pipe manufactured with a weld) is a tubular product made out of flat plates, known as skelp, that are formed, bent and prepared for welding. Manufactured in accordance with AWWA Manual M11, we manufacture spiralweld pipe, rolled-and-welded straight seam pipe, and custom pipe from 12” to 156”, and larger if needed. known as skelp, that are formed, bent and prepared for welding. These long-standing protective systems prevent corrosion, an electrochemical process that oxidases steel in the presence of moisture and oxygen. Stainless steel contains chromium which provides the properties of corrosion resistance at high temperatures. Applied to the pipe exterior, coatings are the first line of protection against corrosion and other elements. Whether transporting water for miles or carrying liquids or gases through pipelines at high pressure, our steel water pipe is made to last. Stainless steel welded pipes made by BUTTING The focus of BUTTING’s business activities is the production of high-quality longitudinally welded pipes made from stainless steels. What is Galvanized Steel Pipe? Moving water from its source to civilization is not a new concept. Search results may not reflect all products, sizes or tolerances of our 60,000 tons of products in stock. Selecting the appropriate joint is critical to any pipeline project. ERW: 3/4″ thru 26″ up to 1.000″ thick DSAW: 20″ thru 72″ up to 3.000″ thick R&W: 24″ thru 120″ up to 4.000″ thick, SA53 / A53 Welded — Grade B API 5L Welded — Grades B (X42, X52, X60, X65 and X70) PSL 1, PSL 2 A671 / A672 in all grades, A/SA-234 — WPW OR WPWX – Grades B, C High Yield MSS SP-75 —Grades WPH (Y42, Y52, Y60, Y65 and above), 24″ thru 120″ OD Wall Thickness — Up to 1.000″, A139/134/AWWAC200 ASTM A252 — Grades 2 & 3, 16″ OD and Larger Wall Thickness — Up to 3.000″, A/SA-234 — WPW OR WPWX (Grades 5, 9, 11, 22, 91). Our factory-applied protective linings isolate the steel pipe while ensuring safe water delivery. Northwest Pipe is the leading manufacturer of engineered steel pipe in North America for many reasons—our quality standards, unrelenting drive in innovation, and ability to solve client challenges are a few of those reasons. It has been used used for water-supply pipes or as a strong tubing for outdoor applications. Technical delivery conditions. Contact a sales rep for the most accurate information. Few companies in Europe can point to such long-standing experience and diversity in the production of pipes. The high tensile strength of steel and its natural resilience to seismic events make it the workhorse that has been around since the 1850s—and still going strong. Match your project requirements with our inventory. Both are designed to provide a permanent watertight seal. Coatings prohibit corrosion, which can occur from corrosive soils, dissimilar metals, bacteria, stresses, or stray electrical current in the ground. for ERW and Hot-dip Galvanized Steel Pipes, Oval pipe, flat oval pipe and elliptic pipe, Stainless Steel Square / Rectangular Tubes, Single-layer anti-corrosion epoxy powder pipe, HDPE (High-density polyethylene jacket pipe), The manufacture of electric resistance welded pipe, HFW influence on welding quality of steel pipe, Fusion welded method of new polyethylene pipe, the production process of welded steel pipe, The Purpose Guidance Of Welded Steel Pipe, ERW oil casing application and market analysis, Spiral steel pipe welding area common defects, Purpose of preheating pipe prior to welding, Longitudinally Submerged Arc Welded Process Flow, Pressure hydrostatic test for welded pipes, Technical support for ERW , SSAW & LSAW stel pipe, Welding advantages of DSAW straight seam steel pipe, The determination methods of deviator for SSAW pipe, Difference between SSAW steel pipe and LSAW steel pipe, Spiral Submerged-arc Welded Quality Assurance, Ultrasonic Test System for SSAW Pipe Weld Seam, what are the defects in pipe manufacturing, ASTM A252-89 Welded and seamless steel pipe piles, Disadvantage and defect of resistance welding, Features of SSAW steel pipe production process, Difference between ERW and SAW steel pipe, Advantage of galvanized spiral pipe welding process, Anticorrosion performance of galvanized mild steel pipe, Difference between galvanized pipe and seamless pipe, Difference between plastic coated and galvanized steel pipe, Difference between black steel and galvanized steel pipe, Difference between galvanized mild and galvanized iron, Difference hot-dip galvanizing and cold galvanizing, Galvanized steel clamp connection technology applications, Galvanized mild steel welded seam welding proces, The technical requirements of galvanized steel pipe, Usage characteristics of thin-walled galvanized l tube, Large-size square & rectangular pipe production process, Rectangular/ Square hollow section process, How to improve rectangular pipe welding technology, Internal and External Anti-corrosion pipe Standard, Between the anti-corrosion & insulation pipes, Electric-Resistance-Welded Carbon Steel and Carbon-Manganese Steel Boiler and Superheater Tubes, Square Pipes for General Structural Purpose, Carbon Steel Tubes for General Structure Purpose, Carbon Steel Tubes for Machine Structure Purpose, Carbon Steel Rectangular Pipes for General Structure.
