今天山東無縫鋼管廠給（gěi）大家介紹一下無縫不鏽方管（guǎn）！

  Today, as an introduction shandong seamless steel pipe to seamless stainless square tube!

  無（wú）縫不鏽方管也稱不鏽鋼無縫鋼管，是用鋼錠或實心管坯經穿孔製成毛管，然後經熱（rè）軋、冷軋或冷撥（bō）製成（chéng）。無縫方管的（de）規格（gé）用外徑（jìng）*壁厚毫米數表示。

  Seamless stainless pipe also called stainless steel seamless steel tube, is made from solid tube ingot or the perforation capillary, then through hot rolling and cold rolling or cold dial.* wall thickness of the specifications of the seamless steel square tube with diameter mm number representation.

  304不鏽方管全稱（chēng）SUS304不鏽方管

  304 stainless square tube full SUS304 stainless pipe

  SUS304不鏽方管屬（shǔ）於美國牌號材（cái）質（zhì）的不鏽方管（guǎn），國內牌號相當於0Cr19Ni9不鏽方管，通常用 0Cr18Ni9替代。

  SUS304 stainless square tube belongs to the American brand material of stainless tube, domestic brand is equal to 0 cr19ni9 stainless tube, usually use 0 cr18ni9 alternative.

  不鏽鋼防鏽的機理是合金元素形成致密氧化膜，隔絕氧接觸（chù），阻止繼續氧化。所以不鏽鋼並不是"不鏽"。

  Stainless steel rust is the mechanism of alloy elements to form dense oxide film, isolated from oxygen contact, prevent to oxidation.Stainless steel is not so "stainless".

  304材料出現生鏽現象，可能有以下幾個原（yuán）因（yīn）：

  304 material appear rusty phenomenon, there may be several reasons:

  使用環境中存（cún）在氯離子。氯離子廣泛存在，比如食鹽、汗跡、海水、海風、土壤等等。不鏽鋼在氯離子存在下的環境中，腐蝕很快，甚（shèn）至超過普通的低碳鋼。 

  Using chloride ion exist in the environment.Chloride ion is widespread, such as salt, HanJi, sea, sea wind, soil and so on.Stainless steel in the presence of chloride ions in the environment, corrosion soon, even more than ordinary low carbon steel. 

  所（suǒ）以對不鏽鋼的使用（yòng）環境有要求，而且需要經常（cháng）擦拭，除去灰塵，保持清潔幹燥。

  So the use of stainless steel environmental requirements, and often need to wipe, remove dirt, keep clean and dry.

  316和317不鏽鋼（317不鏽鋼的性能見後）是（shì）含鉬不鏽鋼種。317不鏽鋼中的鉬含量略高明於316不鏽鋼。由於鋼中鉬，該鋼種總的性能優於310和304不鏽（xiù）鋼，高溫條件下，當硫酸的濃度低於（yú）15%和高於85%時，316不鏽鋼具有廣泛的用途（tú）。316不鏽鋼還具有良好的而氯化物侵蝕的性（xìng）能（néng），所以通常用（yòng）於海（hǎi）洋環境。

  The performance of the 316 and 317 stainless steel (317 stainless steel see after) is molybdenum stainless steel.Molybdenum content of 317 stainless steel was a little bit clever than 316 stainless steel.Because of molybdenum in steel, the steel grade overall performance is better than that of 310 and 304 stainless steel, high temperature conditions, when the concentration of sulfuric acid is less than 15% and higher than 85%, the 316 stainless steel has a wide range of USES.316 stainless steel also has good performance of chloride erosion, so often used in Marine environment.

  不（bú）鏽方管隨著社（shè）會經濟的發展，其應用也得到了越（yuè）來越（yuè）廣泛的普及。必將在各個領（lǐng）域帶來全新的改（gǎi）觀。

  Stainless tube with the development of social economy, the popularization of its application also got more and more widely.Will bring new change in all fields.

  不鏽方管（guǎn）的理（lǐ）論重量：W=(外徑-壁厚)x壁厚x0。02491x長度

    Don't rust square tube theory weight: W = - wall thickness (diameter) x thickness x0.The length of the 02491 x
