X65QS管线无缝钢管
品名：X65QS无缝管线钢管
材质：X65QS
执行标准：API SPEC 5L PSL1/PSL2
制造方法：冷拔（小口径）/热轧（大口径）
热 处 理：正火/回火/淬火
可供货规格：外径21.3~711*壁厚2.77~59.54mm（1/2~28寸*SCH30-160/SCHSTD-XXS）
用途：石油天然气工业管线输送系统用无缝钢管
主要用途：用于石油、天然气工 业中的氧、水、油输送管，海底电缆、通信设施管线管道，海上石油平台建设或低温环境下管道和结构 工程建设；也可用于工程基建建设，林园道路美化，排水管道，厂房钢钩建设，高压电力铁塔。
X65无缝管线管相对抗拉强度和屈服强度都要高，对应的承压能力也提高，在制造过程中以冷拔和热轧工艺来生产，后期进行热处理，常以正火/回火/淬火中一种或两种热处理（客户要求的热处理方式需在合同中注明）状态交货，符合PSL1/PSL2级别。当建设高强度、高韧性、高质量长距离油气管线时，所需钢管大多是此类无缝钢管。另附加3PE（三层聚乙烯防腐涂层）防腐后会延长使用时间。
X65QS无缝管线钢管厂家
X65QS管线无缝钢管零件如果局部硬度要求较高，厂家可用感应加热等方式进行局部淬火热处理，这样的X65QS管线无缝钢管通常要在图纸上标出局部淬火热处理的位置和局部硬度值。X65QS管线无缝钢管的硬度检测要在指定区域内进行。硬度检测仪器可采用洛氏硬度计，测试HRC硬度值，如热处理硬化层较浅，可采用表面洛氏硬度计，测试HRN硬度值。
X65QS无缝管线钢管现货
X65QS管线无缝钢管现货表面淬火回火热处理通常用感应加热或火焰加热的方式进行。主要技术参数是表面硬度、局部硬度和有效硬化层深度。硬度检测可采用维氏硬度计，也可采用洛氏或表面洛氏硬度计。试验力(标尺)的选择与有效硬化层深度和X65QS管线无缝钢管表面硬度有关。这里涉及到三种硬度计。
维氏硬度计是测试热处理X65QS管线无缝钢管表面硬度的重要手段，它可选用0.5~100kg的试验力，测试薄至0.05mm厚的表面硬化层，它的精度是最高的，可分辨出热处理X65QS管线无缝钢管表面硬度的微小差别。另外，有效硬化层深度也要由维氏硬度计来检测，所以，对于进行表面热处理加工或大量使用表面热处理工件的单位，配备一台维氏硬度计是有必要的。
X65QS管线无缝钢管价格
管线管规格：8-1240×1-200mm 管线管
执行标准： API SPEC 5L
用途：用于石油、天然气工业中的气、水、油输送 API SPEC 5L-2007（管线管规范），是美国石油学会编制并发布的，在世界各地通用。 管线管:是把轴出地面的油、气或水，通过管线管输送到石油和天然气工业企业。管线管包括无缝和焊接管两种，其管端有平端、带螺纹端和承口端;其连接方式为端头焊接、接箍连接、承插连接等。
该管主要材质为B、X42、X46、X56、X65、X70等钢级。我公司于2009年8月通过美国API认证(API 5CT 和 API 5L)。山东库现货价格为9100元/吨。
