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

A WINNING COMBINATION WITH VERIFIABLE COST SAVINGS

Result:

Unit has not leaked in 22 Thermal Cycles

Net Savings of over $200,000.00

Lamons fully supports the aim of REACH in improving the protection of human health and the environment through the better and earlier identification of the intrinsic properties of chemical substances. Lamons Gasket products are considered articles and not designed to release any substance under normal and reasonably predictable application scenarios during their lifespan.

Based on the information gathered, no products released to our customers contain Substances of the Very High Concern (SVHC), at or above applicable threshold limits.

Lamons Gasket Company confirms that the products we supply/manufacture are complaint within the restrictions of the current revisions of European Union Regulation listed below:

  • European Union Regulation (EC) 1907/2006, Registration, Evaluation, Authorization, and Restriction of Chemicals (REACH)

RoHS stands for Restriction of Hazardous Substances. RoHS, also known as Directive 2002/95/EC, it restricts the use of specific hazardous materials found in electrical and electronic products. Lamons does not supply components intended for those uses.

Restricted Substances Maximum Threshold Limit
Cadmium and its compounds 100 ppm (0.01 weight %)
Mercury and its compounds 1000 ppm (0.1 weight %)
Hexavalent chromium and its compounds 1000 ppm (0.1 weight %)
Lead and its compounds 1000 ppm (0.1 weight %)
Polybrominated biphenyls (PBB) 1000 ppm (0.1 weight %)
Polybrominated diphenyl ethers (PBDE) 1000 ppm (0.1 weight %)
Bis (2-Ethylhexyl) phthalate (DEHP) 1000 ppm (0.1 weight %)
Benzyl butyl phthalate (BBP) 1000 ppm (0.1 weight %)
Dibutyl phthalate (DBP) 1000 ppm (0.1 weight %)
Diisobutyl phthalate (DIBP) 1000 ppm (0.1 weight %)

 

Additionally, Lamons does not supply components that inhibit compliance with EMA/410/01. Furthermore, products produced and supplied to our customers are within the operating guidelines of California’s Proposition 65.

We believe this information is accurate and is offered in good faith. This information is subject to revision when additional knowledge/information is gained.

Nubbins were traditionally machined onto Heat Exchanger flange facings with the concept that a smaller sealing surface area would require less clamp load to effect a seal. This nubbin is normally 1/64" high by 1/8" wide. Because of the need for a reduced clamp load by use of the nubbin in concentrating the bolt load, many times, flanges with nubbins call for smaller and less bolts.

For flanges with nubbins, Double-Jacketed gaskets have historically been used to effect a seal. As processes have become more rigorous introducing higher temperatures and cycling effects, radial shear has become an issue. Many end-users have invested significantly in machining off nubbins. Lamons has developed and extensively tested our CorruKamm™ gasket in cycling applications utilizing nubbins.

CorruKamm™ is Heavy machined 3/32” thick core faced with .020” APX2 graphite. A machined profile, not formed, allows for correcting alternated geometry strategically indexed and aligned so that deflection occurs. The result is maximum stability, recovery, resiliency, deflection and conformance.

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 July 6, 2018, the U.S. will be imposing a 25% tariff on certain finished good products imported from China under Section 301 of the Trade Act of 1974.

The Lamons impacted items are:

  • Spiral Wound Gaskets
  • LP3 Gaskets
  • Ring Joint Gaskets

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 July 9, 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!

Sincerely,
Marc A. Roberts
President

Dear Valued Lamons Customer,

On March 8, 2018, the President issued Proclamations 9704 and 9705 on Adjusting Imports of Steel and Aluminum into the United States, under Section 232 of the Trade Expansion Act of 1962, as amended (19 U.S.C. 1862), providing for additional import duties for steel mill and aluminum articles, effective March 23, 2018. Section 232 imposed by the federal government placed tariffs on the following items:

Aluminum (10% Tariff)

  • Primary unwrought aluminum, not alloyed
  • Primary unwrought aluminum, alloyed
  • Semi-finished aluminum bars, rods and profiles
  • Aluminum wire
  • Semi-finished aluminum plates, sheets, and strip
  • Foil of all types
  • Tubes and Pipe Extrusions
  • Tube or Pipe Fittings
  • Castings and Forgings

Steel (25% Tariff)

  • Carbon and alloy flat products—produced by rolling semi-finished steel through varying sets of rolls, including sheets, strips, and plates.
  • Carbon and alloy long products—that fall outside the flat products category, including bars, rails, rods, and beams.
  • Carbon and alloy pipe and tube products—either seamless or welded pipes and tubes, some of which may include stainless and alloys other than stainless.
  • Carbon and alloy semi-finished products—consisting of initial, intermediate solid forms of molten steel, to be re-heated and further forged, rolled, shaped, or otherwise worked into finished steel products, including blooms, billets, slabs, ingots, and steel for castings.
  • Stainless steel products—flat-rolled, pipe and tube, and semi-finished forms, containing at minimum 10.5 percent chromium and, by weight, 1.2 percent or less of carbon, offering better corrosion resistance than other steel.

Implementation of these tariffs per Section 232 of the Trade Expansion Act of 1962 has contributed to rising raw material prices both domestically and internationally. 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 June 1, 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!
