Metal-Jacketed Gaskets

Double-jacketed gaskets are probably the most commonly used style of gaskets in heat exchanger applications. Available in virtually any material that is commercially available in 26-gauge sheet. They are also extensively used in standard flanges where the service is not critical. Since most double-jacketed gaskets are custom made, there is virtually no limit to size, shape or configuration in which these gaskets can be made.

Spiralwound Gaskets


Placeholder

W

A winding is made of alternate plies of a metal wire and a soft non-metallic filler. The metal wire in the gasket is preformed into a “chevron” configuration, allowing superior resiliency and self-adjustment when compared to conventional gaskets. The Style W is just a sealing component (winding) only, which is normally used on tongue and groove joints, male and female facings and groove to flat flange facings.

WR

Style WR gaskets consist of a winding with a solid metal outer guide ring. These gaskets can be used on plain flat face flanges and on raised face flanges. The outer guide ring serves to center the gasket properly in the flange joint, acts as an anti-blowout device, provides radial support for the Spiral Wound components, and acts as a compression gauge to prevent the Spiral Wound component from being crushed. Normally the outer guide rings are furnished in mild steel, but can be supplied in other metal when required by operating conditions.

WRI

Style WRI is identical to style WR, with the addition of an inner ring. The inner ring also serves several functions. Primarily, it provides radial support for the gasket on the I.D. to help prevent the occurrences of buckling or imploding. Its I.D. is normally sized slightly larger than the I.D. of the flange bore, minimizing turbulence in process flow. The inner rings are normally supplied in the same material as the spiral wound component. Lamons normally manufactures standard Style WR and WRI spiral wound gaskets to ASME B16.20, designed to suit ASME B16.5 and ASME B16.47 flanges.

WRI-LP

Designed for highly corrosive environments, Style WRI-LP is a Spiral Wound gasket with a conventional outer guide ring and a “Kammpro” style LP-1 inner ring. This dual sealing design engages the raised face completely from the O.D. to the bore. The winding can be constructed with the required metal and soft filler specified by the user. The “Kammpro” inner ring metal can be ordered in any alloy, such as Monel, or in Carbon Steel. A Carbon Steel inner ring can be given a protective PTFE coating for increased chemical resistance. The Kammpro inner ring is faced typically with either 0.020″ thick EPTFE or graphite. The WRI-LP has seen wide-spread approvals for HF Acid service, although this design has much further potential. Its main advantages are: no metal contact with the media; chemical resistance; fire safe design; sizing to meet ASME B16.5; available in large diameter and special flanges.

Kammpro

LP1

Kammpro style LP1 is manufactured without a guide ring for tongue and groove, or recessed flange applications such as Male and Female. It is typically used in heat exchanger applications and applied as an upgrade to double jacketed gaskets especially when lower load is needed. It is highly suggested to have the nubbin (if present) machined out when applying Kammpro LP1 in heat exchanger applications.

LP2

Kammpro style LP2 is constructed with an integral guide ring for aligning purposes. It is suggested to be used in raised face flanges. The sealing core is designed and sized per EN-12560-6 spec and depending on the flange specification the guide ring is sized to fit properly.

LP3

Kammpro style LP3 utilizes a loose fitting guide ring. This popular design is preferred to be used for nominal pipe size and pressure class raised face flanges and is used in equipment with excessive radial shear characteristics, thermal cycling, and expansions. The sealing core is designed per EN-12560-6 spec and the guide ring is sized to suit the flange specification.

Max Temperature rated up to 1500° F.

RTJ Gaskets

Oval/Octagonal

API ring Joint gaskets come in two basic types, an oval cross section (Style 377) and an octagonal cross section (Style 388). These basic shapes are used in pressures up to 10,000 psi. The dimensions are standardized and require specially grooved flanges. The octagonal cross section has a higher sealing efficiency than the oval and would be the preferred gasket. However, only the oval cross section can be used in the old type round bottom groove. The newer flat bottom groove design will accept either the oval or the octagonal cross section. The sealing surfaces on the ring joint grooves must be smoothly finished to 63 micro inches and to be free of objectionable ridges, tool or chatter marks. They seal by an initial line contact or a edging action as the compressive forces are applied. The hardness of the ring should always be less than the hardness of the flanges to prevent flange deformation. Dimensions for API ring joint gaskets and grooves are covered in ASME B16.20 and API6A. Lamons stocks a wide range of sizes and materials ready for immediate shipment from R11 to R105. Stock materials include large variety of metals.

Jet Lube 550

Lamons Premium Thread Lubricant and Anti-Seize has advanced engineered compounds that are unsurpassed in the two most fundamental areas of concern to proper joint assembly; make-up torque and disassembly or break-out torque. Where torque is produced, friction is present. Correct control of friction is critical when applying proper bolt load. Proper and consistent bolt loads are essential to correct gasket stress and a good joint assembly. Premium Thread Lubricant will enhance and ensure easy assembly and a smooth disassembly. What truly sets Lamons Premium Thread Lubricant apart is the distinctly high percentage of volume solids content. Over time, and with exposure to extreme temperatures and elements, our blends will remain primarily intact. In fact, in many cases, our lubricants can even condition the mating surfaces.

Load-Indicating Studs

SPC4TM load indicating fastener technology allows installation of a bolted assembly with confidence. Users can monitor the clamp load of any SPC4TM bolted joint whether static or dynamic, by attaching an indicator datum disc located on the end of the fastener and reading the value with a user friendly mechanical indicator. The benefits of this concept allow the fastener to be loaded many times as long as the stress remains in the elastic range, meeting the criteria of ASTM F2482. An accurate assessment of loading can also be obtained after the joint has been put into service.
