Bolts, Nuts and Gaskets

Dutcotennant understands that providing effective supply chain management of piping materials is the key to making a project successful, keeping it on track and reducing costs. Fast turnaround and reliable deliveries are of paramount importance in keeping downtime to a minimum during maintenance periods.

Its Pipeline division manufactures special flanges and fittings and will source ancillary products such as pipe, gaskets, and plugs, to complete the package.

Gaskets are necessary components used to assure leak-free flange connection. Gaskets are compressible sheets or rings used to make a fluid-resistant seal between two surfaces. They are designed to operate under extreme temperature and pressures and are available in a wide range of metallic, semi-metallic and non-metallic materials. The principle of sealing is the compression from a gasket between two flanges. A gasket forms a seal to keep liquid and gases which is formed after filing the microscopic spaces and irregularities of the flange faces. For a leak-free flange connection, correct installation of damage-free gaskets is required.

Bolts, on the other hand, are required to connect two flanges with each other. The quantity will be given by the number of bolt holes in a flange, diameter and length of bolts are dependent on flange type and Pressure Class of flange. Majorly in the Petro and chemical industry stud bolts are used for ASME B16.5 flanges. Stud Bolts are made from a threaded rod using two nuts. The other type of available bolt is the machine bolts that using one nut.

Dutco Tennant LLC supplies a wide range of pipe plugs for just about any application. We know that you never know what project is going to be thrown your way. That’s why we go the extra step to make sure that you have the tools and equipment that you need. Our mechanical pipe plugs come in a wide variety of sizes and materials to handle any project requirements. Our dedicated team of professional experts is always there to help you determine the right type/style of plug for your situation. A few information from you will let our team help to determine what type of plug would be the best option…what size? what does the plug need to hold back, how much backpressure, and how long is the plug going to be in place? Other issues (chemicals/temperature, etc.) may have to be considered as well. For long term applications and very high pressure, we often recommend an aluminum mechanical pipe plug.
