Stainless steel-Electric Resistance Welded (ERW) Pipe-Welded (ERW) Pipe
Steel pipes come in many forms and sizes. Seamless pipes are a non-welded option produced from hollowed-out steel billets. When it comes to welded steel pipes, there are three options: ERW, LSAW and SSAW.ERW pipes are made from electric resistance welded steel plates. LSAW pipes are made from longitudinally submerged arc welded steel plates. SSAW pipes are made from spiral submerged arc welded steel plates.Steel pipes are typically used in the oil and gas industry for exploration and extraction (upstream), the transmission of fluids like oil, gas and slurries (midstream) and oil refinement into derivative products (downstream). They are also used for agricultural irrigation, urban construction and more.Let’s take a closer look at each type of pipe, comparing their differences and how to make an order with the right description.続きを読む -
High Frequency Electric Weld (ERW) Line Pipe and Standard Products-ERW Steel Pipe
U. S. Steel Tubular Products high frequency electric weld (ERW) line pipe and standard electric resistance weld pipe products are smoothly finished and thin-walled. They are produced by continuously forming coiled hot rolled strip into a tube and welding the longitudinal seam using high-frequency electric resistance welding. Chemical and mechanical property requirements are as prescribed by current API 5L and applicable ASTM standards.ERW standard pipe and high frequency electric-welded line pipe are widely used throughout the oil and gas industry, as well as for pipe piling and cable pipe systems. With over a century of producing steel products for the energy business, U. S. Steel Tubular Products offers a variety of manufacturing methods to produce steel pipe that can meet our clients’ specific requirements.

How Is Steel Tubing Made?-Steel Tubing
Iron ore and coke, a carbon-rich substance from heated coal, are melted into a liquid substance in a furnace and then blasted with oxygen to create molten steel. This material is cooled into ingots, large castings of steel for storing and transporting materials, that are shaped between rollers under high amounts of pressure.Some ingots are passed through steel rollers that stretch them into thinner, longer pieces to create blooms, intermediates between steel and iron. They are also rolled into slabs, pieces of steel with rectangular cross-sections, through stacked rollers that cut the slabs into shape.続きを読む -
Structural steel Pipe-ERW Steel Pipe
People have used pipes for thousands of years. Perhaps the first use was by ancient agriculturalists who diverted water from streams and rivers into their fields. Archeological evidence suggests that the Chinese used reed pipe for transporting water to desired locations as early as 2000 B.C. Clay tubes that were used by other ancient civilizations have been discovered. During the first century A.D. , the first lead pipes were constructed in Europe. In tropical countries, bamboo tubes were used to transport water. Colonial Americans used wood for a similar purpose. In 1652, the first waterworks was made in Boston using hollow logs.続きを読む -
Methods of Manufacturing used in the Metal Pipe and Tubing Industries-ERW Steel Pipe
電気抵抗溶接チューブまたは ERW チューブとも呼ばれるこのチューブは、鋼のストリップをローラーに通して希望の形状に成形して作られます。次に継ぎ目を溶接し、チューブの内側と外側の長さに沿ってフラッシュを形成します。次に溶接部をテストして、基準を満たしていることを確認します。溶接部がテスト プロセスに合格すると、チューブは正確なサイズに成形され、まっすぐにされ、長さに合わせて切断されます。ERW チューブとパイプは、溶接フラッシュあり、フラッシュなし、またはフラッシュ制御 (通常 0.010 インチまで) で入手できます。続きを読む -
HOW IS STAINLESS STEEL TUBING PRODUCED?-China Steel Pipe
原材料は熱間押出しされたシームレス パイプの形で始まり、その後冷間圧延され、チューブ レデューサーで長くまっすぐな形状に加工されます。冷間圧延は、長いチューブを製造するのに最も効果的な製造方法です。圧延されたパイプは必要な長さに切断され、破片を取り除くために洗浄され、成形または溶接プロセス中に発生する可能性のある応力を除去するために熱処理が行われます。チューブの製造にはさまざまな熱処理を使用できますが、特にアニーリングは金属の構造を改善し、用途での使用に適した延性を高めます。続きを読む -
溶接管製造 - ERW鋼管
チューブとパイプという 2 つの言葉は、どちらも中空形状であることから、しばしば同じ意味で使用されますが、溶接チューブとシームレス チューブのニーズを判断する際には、この 2 つの間には重要な違いがあります。チューブは外径 (OD) と壁の厚さで測定されます。一方、パイプは内径 (ID) で測定されます。機能面では、チューブは一般に構造的および美観的な用途で使用され、パイプは流体、液体、ガスの輸送に使用されます。続きを読む -
溶接管はどのように作られるか? - ERW 鋼管
溶接チューブの大規模な製造は、複数のステップを含む複雑なプロセスです。最初に、完成したチューブの壁の厚さと一致する厚さの金属コイルを選択します。コイルは、必要な円周と直径を実現できるように十分な幅も必要です。コイルは一連のダイに通され、形作られます。これにより、コイル幅の 2 つの端が互いに近づき、一方の端がもう一方の端に接するチューブが形成されます。この 2 つの端を接合するには、溶接プロセスが使用されます。溶接チューブの製造プロセスによっては、この時点で余分な溶接補強材が除去される場合があります。新しく形成されたチューブは、必要な仕様に応じて熱処理プロセスを受ける場合もあります。次に、チューブを必要な長さに切断します。続きを読む
