Abstract
สารเคลือบผิวหล่อลื่นซึ่งปราศจากโลหะหนักเป็นอันตรายก่อตัวบนข้อต่อเกลียวพิเศษสำหรับ ท่อประกอบกันขึ้นโดยหมุดและกล่องซึ่งมีผิวหน้าสัมผัสประกอบรวมด้วยส่วนสัมผัสส่วนเกลียวและ ส่วนสัมผัสโลหะไม่เป็นเกลียว (ผิวหน้าผนึกและบ่า) เพื่อจัดให้มีข้อต่อที่มีคุณสมบัติการต่อต้านการเกิด รอย,การกัน-ก๊าซ,และต่อต้านการกัดกร่อนที่ว่าส่วนสัมผัสโลหะไม่เป็นเกลียวป้องกันจากการคราก แม้เมื่อข้อต่อที่สร้างขึ้นมีแรงบิดสูง สารเคลือบผิวหล่อลื่นประกอบรวมด้วยหนึ่งหรือทั้งสองของโรซิน และแคลเซียมฟลูออไรด์, เมทัลโซพ,แว็กซ์,และเกลือโลหะเป็นเบสของกรดอะโรเมติกอินทรีย์,และ ที่ควรใช้ต่อมารวมถึงผงหล่อลื่น,แมกนีเซียมคาร์บอเนต,และ/หรือคาร์โบไฮเดรต,โดยเฉพาะไซโคล เด็กซ์ทริน A lubricant free of harmful heavy metals forms on a special threaded connection for The tubes are assembled by pins and boxes whose faces are composed of threaded and Metal contacts are not threaded. (Sealing face and shoulder) to provide a joint with anti- Welded, anti-gas, and anti-corrosive properties that the metal contacts are not threaded prevent from yielding Even when the joint created has high torque The lubricant coating consists of one or both of rosin. And calcium fluoride, metal soap, wax, and metal salt are bases of organic aromatic acids, and Subsequent uses include lubricating powder, magnesium carbonate, and / or carbohydrates, especially cyclodextrin.
