The fluoropolymer used in the final coat of FluoroKote#1® has a kinetic friction coefficient of 0.06-0.08. Also known as PTFE Coated Bolts and Nuts. PTFE is short for Polytetrafluoroethylene, a chemical applied to common bolting materials (such as B7 stud bolts) to provide corrosion and chemical resistance.. The B7 studs with 2H nuts are commonly used by turnaround groups, operations and maintenance departments, and contractors at many chemical plants, refineries, and offshore platforms. ANSI / API 6A / ISO 10423:2003 Feb. 1, 2005, ASTM A320 L7 Tensile and Yield Strength Any thread damage (however minor), additional lubrication, or standard deviations within the range can change friction and thereby the expected outcome. In this article, we’ll refer to all of them as PTFE. Consult LGT Engineering for flange bolt-up procedure, target bolt stresses, and guidelines for non-standard connections. K= friction coefficient. Not so with Maudlin. Table is for standard pipe flanges only. Bolt Torque Calculator - Calculate required bolt torque; Improvised Torque Wrench - Improvised torque wrench with luggage scale; ISO 724 - Metric Threads - Dimensions of metric threads according ISO 724; Metric Bolt Head and Wrench Size - ANSI/SO, DIN and JIS bolts HEAVY HEX NUTS ASSEMBLED. Product Type: Expansion Joint. Extreme caution should be used when using a formula for torque/tension relationships. Tighter corrosion tensions are achieved with less requeired torque. The coating’s chemical resistance, and easy on/easy off characteristics are perfect for these environments. Maudlin & Son Manufacturing, a Houston, TX, company was built on three unwavering commitments – a commitment to craftsmanship, quality, and meeting the most demanding industrial requirements. bolting torque table 2a - cold service astm a320 grade l7 stud bolts.
