Dear Valued Lamons Customer,

On March 22, 2018, President Trump signed a memorandum announcing that the United States would take multiple steps to protect American technology and intellectual property from certain discriminatory and burdensome trade practices by China. These actions were announced following a report by the Office of the U.S. Trade Representative (USTR) regarding China's acts, policies and practices with respect to technology transfer, intellectual property and innovation. Therefore, effective September 24, 2018, the U.S. will be imposing a 10%, (with additional 15% on January 1, 2019) tariff on certain finished good products imported from China under Section 301, section III of the Trade Act of 1974.

The Lamons impacted items are:

  • B7, B7M, B16, B8, B8M Rod & studs
    • Also includes coated

Due to this tariff implementation, there may be items you purchase from Lamons that could be affected by this tariff. Please contact your Lamons Sales Representative for the changes to your affected products. The pricing changes will be effective Nov 5, 2018.

Lamons is committed to continuing to meet our Customers' requirements while also delivering a top-quality product, therefore, we made this decision after thoroughly considering all options. Additionally, we will keep you informed of any other impacts that might result from additional tariffs being imposed by our government.

Thank you for being our Valued Customer!

Remember, Not all fluoropolymer coatings are created equal. Fasteners coated with Fluorokote#1® prove to be longer lasting, safer and more cost effective than any other coated fastener. Lower your plant maintenance cost and increase safety & reliability by using FluoroKote#1® coated fasteners. The next time you get ready to order PTFE coated bolts & nuts, ask your vendor if they can provide these results!

HF Alky Regeneration Heat ExchangerPictured—HF Alky Regeneration Heat ExchangerLamons was tasked with sealing a Heat Exchanger that had been leaking for almost 20 years which utilized standard double jacketed gasket technology in conjunction with standard B7 fasteners. 

Exchanger was leaking both steam from the shell side and isobutane (feed product for Alkylation unit) from the tube side.

We proposed using:

  • Lamons CorruKamm gaskets due to their resilience and recovery in high cycling environments
  • SPC4 Load Indicating Stud Technology – Intelligent Fasteners where torque can be validated by indicating the load applied
  • Belleville washers




Unit has not leaked in 22 Thermal Cycles
