Examining electric resistance weld nuggets in tube and pipe

The ERW tube and pipe industry usually separates the power sources available into the low-frequency range (rotary electrodes) and the high-frequency range (induction coil or sliding contacts).Heat penetration into the edges of in-process material--usually hot-rolled steel--may be as deep as 0.375 inch when welded with a low-frequency power source.Erw Pipe Mill To Cambodia - Welded Pipe Forming machine it took us one month to produce this machine we use the best quality materials and most detailed inspection to make sure our customers are satisfied and our engineers will arrive in Cambodia to help installation and commissioning until the line run smoothly.TY 60 ERW pipe mill ,this model machine can produce OD:25mm-76mm TH:1.0mm-3.2mm steel pipe maximal speed is 80m/minERW carbon steel pipe vs spiral pipeERW carbon steel pipe vs spiral pipe First,the difference between the production process ERW carbon steel pipe is the hot rolled coil through the continuous roll forming,the use of high-frequency current skin effect and proximity effects,so that the edge of the coil heat fusion,pressure in the squeeze roller under pressure welding to achieve production.

Differences between ERW Steel Pipe and HFW Steel Pipe

High frequency welding (HFW) steel pipe is that ERW pipe produced with a welding current frequency equal to or greater than 70 kHZ.Through high-frequency current welding resistance,the heat generated in the contact objects,so the objected surface are heated to the plastic state,then with or without forging to achieve a combination of steels.Dealing with Low-Frequency-Welded ERW-jfkStarting in 1962,manufacturers began to convert ERW mills from low-frequency-welding equipment to high-frequency equipment (450,000 cycles).After 1978,it is believed that few if any low-frequency welders were still being used.With the use of high-frequency current,the problem of contact resistance is virtually nonexistent.China Welded Pipe Mill manufacturer,ERW Welded Pipe Mill Shanxi Haina H-tech Precision Machinery Co.,Ltd is a high-tech enterprise specializing in designing and manufacturing pipe making machine,as like ERW Line,straight seam submerged-arc pipe welding machine,large diameter stainless pipe welding machine,precise stainless industial pipe welding machine,square and rectangle pipe machine,cold roll forming machine,spiral welded pipe mill
