• ​The different types of Welded Steel Pipe You Should Know About

    If you’ve ever been to a construction site, chances are that you must have seen a steel pipe of some sort. Be it short, long, round, thin or thick. It’s a material that is commonly used particularly in the construction industry. Here’s where to buy high-pressure fuel pipe

    There are principally two forms of welded steel pipe – Longitudinal and spiral welded pipe.

    The Longitudinal production process is simple, high efficiency, low cost, rapid development. Spiral Welded Longitudinal is generally higher, can narrow the billet production of large diameter pipe, you can also use the same width of the billet production of different pipe diameters.

    Types of welded steel pipe

    1. Low fluid delivery welded steel pipe (GB / T3092-1993), also known as general welded pipe, commonly known as the clarinet. Welded steel pipe for conveying water, gas, air, oil and heating steam and other general low-pressure fluid and other uses. Divided into ordinary steel pipe wall thickness and pick thicker steel; take over end into the form without the steel tube (fluorescent tubes) and with a steel pipe.

    Steel pipe with a nominal diameter size (mm), said nominal diameter is the diameter of the approximation. Traditionally commonly expressed in inches, such as 11/2 and so on. Low pressure liquid delivery welded steel pipe for conveying fluids in addition to direct, but also widely used as low-pressure fluid high precision galvanized steel tube original.

    2. The low-pressure fluid galvanized welded steel pipe (GB / T3091-1993), also known as galvanized welded steel pipe, commonly known as white tube. Is used for conveying water, gas, oil and air heating steam, heated and other general low pressure fluids or other uses of hot-dip galvanized welded (furnace brazed or welded) steel pipe.

    Pipe wall thickness is divided into ordinary galvanized steel pick and thicker galvanized steel; take over end into the form of a threaded galvanized steel pipe without threaded galvanized steel and band. Steel pipe with a nominal diameter size (mm).

    Traditionally denoted in inches, such as 11/2 and so on. (Tianyang Steel Tube)

     

     

    3. Ordinary carbon steel wire casing (GB3640-88) is the industrial and civil construction, installation of machinery and equipment and other electrical installation work for the protection of steel wires.

    4. straight seam welded steel pipe (YB242-63) is parallel to the longitudinal welds and steel pipe. Usually divided into metric welded steel pipe, welded tube, transformer cooling tubing and more.

    5. Pressure fluid transport spiral submerged arc welded pipe (SY5036-83) is a hot-rolled steel strip coils for the tube, often warm spiral shape, with double-sided submerged arc welding method for pressurized fluid transport spiral pipe joints. Strong pressure steel, welding performance, through a variety of rigorous scientific examination and testing, the use of safe and reliable. Pipe diameter, high transmission efficiency, and can save the laying of pipeline investments. Mainly used to transport oil, natural gas pipelines.

    6. Pressure fluid transport with spiral seam high frequency welded steel pipe (SY5038-83) is a hot-rolled steel strip coils for the tube, often warm spiral shape, using high-frequency welding lap welding method for pressurized fluid transport spiral seam high frequency welded steel pipe. Strong pressure steel, plastic, and easy welding and machining molding; and through a variety of rigorous scientific examination and testing, the use of safe, reliable, pipe diameter, high transmission efficiency, and save the laying of pipeline investments. Mainly used for laying transport oil, natural gas pipelines.

    7. The general low-pressure liquid delivery spiral submerged arc welded pipe (SY5037-83) is a hot-rolled steel strip coils for th- tube, often warm spiral shape, using double-sided automatic submerged arc welding or welding into the legal system for water, gas, air and steam low pressure liquid delivery SAW pipe.

    8. The general low-pressure liquid delivery spiral seam high frequency welded steel pipe (SY5039-83) is a hot-rolled steel strip coils for the tube, often warm spiral shape, using high-frequency welding lap welding method for low pressure liquid delivery spiral seam high frequency welded steel pipe.

    9. Pile with spiral welded steel pipe (SY5040-83) is a hot-rolled steel strip coils for the tube, often warm spiral shape, using double-sided submerged arc welding or high frequency welded for civil engineering structures, piers, bridges such as steel pipe pile foundation.
