Baffle Seals Help Improve Heat Transfer
Shell-and-tube heat exchangers with removable tube bundles require that manufacturing clearances are present to facilitate the insertion and removal of the tube bundles for maintenance, repair or cleaning purposes.
For heat exchangers designed for multipass flows within the shell — for example, Tubular Exchanger Manufacturers Association standard shell types F, G and H — it is common to incorporate a longitudinal baffle plate within the tube bundle design. These plates direct the shell fluid flow in desired directions to increase the dwell time of the fluid while in contact with the tubes, thereby increasing the heat transfer effectiveness of the exchanger.

STAMP - Remember this for Gasket Selection Criteria
When you're specifying a gasket for even the simplest application, it is important that the gasket supplier know all the operating parameters.
There are five major pieces of information needed to select the appropriate gasket, known by the acronym S.T.A.M.P.:
Size:
While gaskets are most often used in standard ANSI flange connections

Rare and Ultra-Pure Resources Present Unique Challenge to Finding Appropriate Low Temp Gasket
Modern technology often requires rare or ultra-pure materials that can only be handled or obtained within extreme environmental conditions. These same conditions present unique and hazardous difficulties when transporting or utilizing these resources. Resources such as liquid oxygen, nitrogen, or argon; all of which are classified as “industrial gases” are handled well below the normal temperature ranges that every-day liquids exist; ranging as low as -195.8°C (-320.4°F). This often makes it a challenging task to find a low temp gasket to fit the specifications for the application.
As an example, let’s look at argon; an important gas used in Welding, Neon Lights, 3D Printing, and Metal Production, just to name a few. It is far more economical to house and transport argon in its liquid state. However, it must be held at an astonishingly low -185.9°C. Fitting the pipes together and maintaining

In addition to KLINGER's complete Sheet Gasketing Product Line which now includes the new major change in construction of their PTFE Products TC 1003, TC 1005, and TC1006, they have added a great new product to cover additional applications during day-to-day operation.
The KLINGER SAVER
A new product we are featuring on our blog is THE KLINGER-SAVER - a tool to eliminate hand injuries.Bolt tightening or loosening activities, or using slug wrenches and hammers can often the cause of serious finger or hand injuries.
The KLINGER-SAVER is a safety device that allows an assembly technician to remove his hand from the potential danger of being struck by the hammer.

WaterSIL is a universal high-pressure gasket material that is certified to NSF 61 and meets strict chemical leaching requirements.
Specially formulated compressed gasket material based on NBR and aramid fiber, Thermoseal WaterSIL is a universal high-pressure gasket material that is certified to NSF 61 and meets strict chemical leaching requirements.
Applications: NSF/ANSI 61 certified gasket material for use in potable drinking water systems and fixtures for public drinking water, food and beverage, hospitality and plumbing supplies.
Benefits of Products Certified to NSP/ANSI 61 Drinking Water System Components
Potable water systems have miles of piping and other devices such as pumps, meters and valves. All of these components require gaskets. Gasket materials certified to NSF/ANSI 61 ensure the safe passing of water on its journey to the consumer's tap.
NSF/ANSI 61 establishes minimum health effect requirements for the chemical contaminants and impurities

Sealex® joint sealant, specially processed, 100% pure PTFE on a roll, provides soft, highly compressible gasketing for longer life and trouble-free sealing. Its form-in-place versatility also cuts maintenance and storage costs. The high compressibility of Sealex® enables it to effectively fill flange imperfections for a tight, leak-free seal. Under pressure, it provides a very wide, thin ribbon-like joint sealant. Unlike conventional PTFE which is prone to cold flow, Sealex® has good creep resistance and bolt torque retention properties.
Sealex® joint sealant does not support bacterial growth or cause product contamination and is FDA compliant. It has virtually no shelf-life concerns since PTFE is unaffected by normal environmental conditions.
It has excellent resistance properties to chemical attack. It is ideal for most chemical services at temperatures to 500°F (260°C) and pressure to 2,000 psi (138 bar). It is also suitable for cryogenic use to -321°F (-196°C).

This blog provides guidance to maintenance operators, engineers and fitters to ensure successful gasket installation and assembly of bolted flange connections. However always check plant-approved installation procedures first.
The successful operation of a gasket depends upon a multiplicity of factors including the style and quality of the gasket material, but also the medium being sealed, the flange design, the amount of pressure applied to the gasket by the bolts and how the gasket is assembled onto the flanges and tightened. Very basic causes often lead to leakage in bolted joints, and in most cases, it is not just the gasket but also the human element. Users should evaluate all conditions to validate the products are suitable for the intended process.
Tools Needed
Specific tools are required for cleaning the flange and tensioning the bolts. Always use standard safety equipment and follow good safety practices. The following tools are required for removal of the old gasket and installation of the new gasket:
- Calibrated torque wrench or hydraulic tensioner
- Brass wire brush
- Personal safety equipment
- Lubricants for the bolts (if specified)
- Other plant-specified equipment
