High Frequency Straight Seam Welded Uses In Water 8"ERW Steel Pipe
Standard for straight seam steel tubes :(GB/T3091-2008) This standard includes straight seam high frequency resistance welded (ERW) steel tubes, straight seam submerged arc welded (SAWL) steel tubes and spiral seam submerged arc welded (SAWH) steel tubes.(GB/T3091-2008) galvanized welded steel pipe for low pressure fluid transportation (GB/T3091-2008), also known as galvanized welded steel pipe, commonly known as white pipe, is due to the transportation of water, gas, air oil and heating steam, warm water and other general low pressure fluid or other purposes of steel pipe, steel pipe specifications with nominal caliber (MM), nominal caliber is the approximate value of the inner diameter.
Straight seam welded pipe, with hot or cold rolled steel plate or steel strip coil welding made of steel pipe on the welding equipment for straight seam welded pipe are called straight seam welded pipe.(because the welding of steel pipe into a straight line so named).
ERW steel pipe is straight seam Resistance Welding pipe, English Electric Resistance Welding, abbreviated as ERW, used for transporting oil, natural gas and other vapor liquid objects, can meet the high and low pressure requirements, currently in the world's transportation pipe field occupies a pivotal position.The biggest difference between ERW steel pipe and seamless steel pipe is that ERW has a weld, which is also the key to the quality of ERW steel pipe.Modern ERW steel tube production process and equipment, because of the international, especially the United States and other years of unremitting efforts, so that the seamless ERW steel tube has been a relatively satisfactory solution.Due to the use of hot rolled coil as raw material, the wall thickness of ERW steel pipe can be controlled within ±0.2mm or so, the two ends of the steel pipe are in accordance with the American APL standard or GB/T9711.1 standard, the end is repaired and beveled, and the delivery length is fixed.
