  • Welded pipe
    Welded pipe sizes and dimensionsWelded pipes are used especially for pipeline constructions and for larger dimensions in the process plants; any specifications and qualities are part of our supply program.For example, we supply carbon steel pipes for pipeline projects throughout the world according to:API 5L X 52, X60, X65, X70Welded carbon and alloyed process plant pipes in acc. to below standards:ASTM A333, 671, 672, 691Welded Stainless steel, special alloys pipes for chemical and petrochemical plants to:ASTM A 312, 358, 778, 928, ASTM B 619, B725All materials are also available in acc. to equivalent DIN/ EN standards and grades.
  • Welding pipe
    Welding pipes used in billet steel sheet or strip, its different welding process is divided into the furnace pipe, welded (ERW) pipes and automatic arc welded pipe. Because of the different forms of welding is divided into two kinds of Longitudinal and spiral welded pipe. Its end shape is divided into circular pipe and shaped (square, flat, etc.) pipe. Welded pipes of different materials and its use is divided into the following varieties:GB / T3091-2008 (low pressure fluid welded steel pipe). Mainly used for conveying water, gas, air, oil and heating hot water or steam generally lower pressure fluid and other uses tubes. The representative material for: Q235A grade steel.GB / T14291-2006 (mine fluid delivery welded steel pipe). Mainly used for mine air pressure, drainage, gas discharge axis with straight seam welded steel pipe. The representative of material Q235A, B grade steel.GB / T12770-2002 (mechanical structure with stainless steel welded pipe). Mainly used for machinery, automobiles, bicycles, furniture, hotel and restaurant decoration and other mechanical components and structures. The representative of material 0Cr13,1Cr17,00Cr19Ni11,1Cr18Ni9,0Cr18Ni11Nb like.
  • Welded steel tube
    Applications RangeThe products are widely used in water engineering, petrochemical industry, chemical industry, power industry, agricultural irrigation, urban construction, it is one of 20 key product of development. For the transport of liquids: water supply, drainage. Used for gas transportation: gas, steam, liquefied petroleum gas. For structural purposes: as piling pipe for bridges; piers, roads, buildings and other structures tube.

  • Welded tube
    Longitudinal production process is simple, high production efficiency, low cost, rapid development. Spiral Welded Longitudinal generally higher than, can narrow the billet production of large diameter pipe, you can also use the same width of the billet production of different pipe diameters. However, compared with the same length of straight seam pipe, weld length of 30 to 100%, and lower production rate.General pipe used to transport low pressure fluid. With Q195A, Q215A, Q235A steel. It can also be used for other soft easy to weld steel. To make hydraulic pipe bending, flattening and other experiments, there are certain requirements for surface quality, usually delivery length of 4-10m, we are often asked to cut to length (or double length) delivery. Pipe specifications with nominal diameter representation (millimeters or inches) nominal diameter different from the actual, ordinary steel pipe and thicker steel pipe two kinds of predetermined wall thickness, steel tube end form was divided by threaded and non-threaded two kinds of table 6-17 of welded steel pipe size.Without welding wire sets and high frequency resistance straight seam welded pipe, nor do they need to do across the grounding line repainting, eliminating the traditional welding and wire sets and other complex construction process. Just a straight pipe joint connecting tube and pipe, pipe fitting and even after the weight on the bar management junction boxes, positioning special tool to tighten (wring) to screw with the junction box at the high-frequency resistance seam welding with a lock nut tight It can set. Pipe bend with the elbow can be bent corresponding field curvature.
