Abstract

DC60 (03/02/57) ท่อไร้ตะเข็บถูกใช้เป็นท่อในเครื่องแลกเปลี่ยนความร้อนของเครื่องแลกเปลี่ยนความร้อน ชนิดท่อติดครีบขวาง และถูกผลิตขึ้นจากอัลลอยทองแดงชนิดหนึ่งที่ประกอบด้วย 0.01 ถึง 0.06 เปอร์เซนต์ โดยมวลของ Fe หรือ 0.04 ถึง 0.06 เปอร์เซนต์ โดยมวลของ Ni และ 0.004 ถึง 0.040 เปอร์เซนต์ โดยมวลของ P โดยส่วนที่เหลือคือ Cu และสิ่งปนเปื้อนที่ไม่อาจจะหลีกเลี่ยงได้, ท่อไร้ตะเข็บนี้มีอัตราส่วน (t/D) ที่ความหนา (ม.ม.) ต่อเส้นผ่าศูนย์กลางด้านนอก (ม.ม.) ที่ 0.04 หรือน้อยกว่า, ความต้านแรงดึง (ซิกมาB) ที่ 245 MPa หรือมากกว่า, ความแข็งแรงจำนน 0.2 เปอร์เซนต์ (ซิกมา0.2) ที่ 130 MPa หรือน้อยกว่า และการยืด (เดลตา) ที่ 40 เปอร์เซนต์ หรือมากกว่า. ท่อไร้ตะเข็บนี้ที่มีความสูง และสามารถนำไปดัดงอเป็นรูปกิ๊บหนีบผม ได้โดยวิธีปกติ DC60 (03/02/57) Seamless tubes are used as tubes in heat exchangers of heat exchangers. Cross-finned tube type and is produced from a type of copper alloy containing 0.01 to 0.06 percent by mass of Fe or 0.04 to 0.06 percent by mass of Ni and 0.004 to 0.040 percent by mass of P with the remainder Cu and non-contaminants. Possibly avoidable, this seamless tube has a ratio (t/D) of thickness (mm) to outer diameter (mm) of 0.04 or less, tensile strength (Sigma B). ) at 245 MPa or more, a strength of 0.2 percent (sigma 0.2) of 130 MPa or less, and elongation (delta) of 40 percent or more. and can be bent to form a hair clip by the normal way
