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.Astm a53 pipe(also referred to as ASME SA53 pipe) is intended for mechanical and pressure applications and is also acceptable for ordinary uses in steam, water, gas and air lines.

It is suitable for welding and for forming operations involving coiling, bending, and flanging, subject to certain qualifications.ASTM A53 pipe covers Seamless and Welded, Black and Hot-Dipped Galvanized nominal (average) wall pipe for coiling, bending, flanging and other special purposes and is suitable for welding. According to the different welding technology of high frequency straight seam welded steel pipe can be divided into straight seam high frequency resistance welded steel pipe and straight seam high frequency inductionwelded steel pipe.The forming process generally adopts the rolling cold forming method.The diameter of high frequency straight seam welded steel pipe is generally small, generally below 660mm or 26in outside diameter.It is characterized by high welding speed. For example, for steel pipes with an outside diameter of less than 1 inch, the welding speed can be up to 200 meters per minute.For 25 inch pipe with outside diameter, the welding speed can be more than 20 m/min.
