ERW (Electro-Resistance Welded) Pipe Line As a result of rapid economic development in China, there is a high demand for good quality, large diameter ERW tubes for the oil & gas transportation, water & sewerage transportation and civil construction industries. To satisfy the requirements of our clients, we have our own patented HAOKUN ERW Tube production line. TO-date, we have supplied large diameter ERW16’, ERW 20”, ERW 24” to our various clients. We with to highlight a case where we have supplied a ERW 25” Tube Mill to Guangzhou Juyi Pipe Factory. In this Mill, we have also designed a Horizontal Loop Accumulator, a high speed Coil Edge Milling and a Flying Curter to enhance its capability. Another ERW 25” Tube Mill is also currently supplied by us to Mozambique WBHO Company. In addition to these references, we have gathered research data for ERW 630 X 19.1 mm steel grade X80 in our design library. We can confidently say that we have acquired state -of-the art know-how for large diameter ERW Tube Mill. Following fast growth of Chinese economy, high-grade, large diameter and high frequency straight seam welded pipes are widely used in areas such as petroleum transportation, urban pipeline networks and constructions, pushing up demand for them, which creates new development opportunities for pipe line manufacturing firms and equipment manufacturers. During the recent years, by learning and absorbing advanced ERW machine technologies from abroad, we designed and developed large diameter ERW production lines with our own intellectual property rights. Especially some single units, such as squeeze roller, have been patented in China. So far, we have finished designing large caliber ERW production lines with specifications: 16″ ERW, 20″ ERW, 24″ ERW. Among those the 20″ ERW, 24″ ERW production mills were already put into operation; For Guangzhou Juyi Steel Pipe Manufacturing Co., Ltd, another complete set of 25″ ERW production line with horizontal loop. High Speed Edge Milling Machine with sawmill. Cutting Machine and Finishing Area, was already in operation; a complete set of 25′ERW line to be exported to WBHO in South Africa is already under testing. In addition, our company has mastered all techniques for ERW630x19.1mm with iron grade X80, and has developed JCOE1420x32mm with iron grade X80 welded pipe production line.

ERW (Electro-Friotaíocht Táite) Líne Pipe Mar thoradh ar fhorbairt eacnamaíoch tapa sa tSín, tá éileamh ard ar chaighdeán maith, feadáin trastomhas ERW mór do na tionscail ola agus gáis iompar, uisce agus séarachas iompar agus tógála sibhialta. A shásamh ar riachtanais ár gcliant, ní mór dúinn ár n-paitinnithe HAOKUN ERW líne a tháirgeadh Tube féin. TO-dáta, ní mór dúinn fáil ERW16 trastomhas mór ', ERW 20 ", ERW 24" ar fáil dár gcliaint éagsúla. Táimid le chun aird a tharraingt ar chás mar a tá soláthar a ERW 25 "Muileann Tube a Guangzhou Juyi Pipe Factory. Sa Mill, ní mór dúinn a ceapadh freisin Lúb accumulator Cothrománach, luas ard Coil Edge Milling agus Curter eitilt chun a chumas a fheabhsú. Eile is ea ERW 25 "Muileann Tube ar fáil freisin faoi láthair ag dúinn Mósaimbíc WBHO Company. Chomh maith leis na tagairtí, ní mór dúinn a sonraí taighde a bailíodh le haghaidh ERW 630 x 19.1 mm grád cruach X80 inár leabharlann dearadh. Is féidir linn a rá go muiníneach go bhfuil faighte againn stáit -de-an ealaín fios gnó le haghaidh trastomhas mór Muileann ERW Tube. I ndiaidh fás go tapa ar gheilleagar na Síne, ard-ghrád, trastomhas mór agus seam minicíocht ard díreach táthaithe píopaí a úsáidtear go forleathan i réimsí cosúil le iompar peitriliam, líonraí píblíne uirbeach agus tógálacha, ag brú suas éileamh orthu, a chruthaíonn deiseanna forbartha nua do líne píopa gnólachtaí déantúsaíochta agus monaróirí trealamh. I rith na blianta beaga anuas, ag foghlaim agus a ionsú teicneolaíochtaí meaisín chun cinn ERW ó thar lear, atá ceaptha againn agus a fhorbairt línte táirgeachta mór trastomhas ERW lenár cearta maoine intleachtúla féin. Go háirithe roinnt aonad amháin, mar shampla sorcóir squeeze, a bheith paitinnithe sa tSín. Go dtí seo, ní mór dúinn críochnaithe a dhearadh línte táirgeachta mór scoth ERW le sonraíochtaí: 16 "ERW, 20" ERW, 24 "ERW.
