    • What is Sanitary Pipe Fitting?

    Sanitary fittings are specialized plumbing components used in hygienic applications, such as those in the food, beverage, and pharmaceutical industries. They are designed to maintain cleanliness, prevent contamination and promote health and safety. These fittings include items such as valves, elbows, tees, clamps, and gaskets that are made of materials such as stainless steel or other non-porous materials. They are used to connect tubes and process equipment in a sanitary manner.

    Features of Sanitary Pipe Fitting

    High Port Density

    Manufacturers produce sanitary fittings with a number of ports on them to reduce the number of connections through which fluids must pass. This helps conserve space on equipment and reduces the time used to set up the equipment.

    Space-Saving

    Because sanitary pipe fittings have multiple ports, they allow fluids to be routed through a single connection. This means that less piping needs to be installed, so there is less space required for machinery to house these components.

    Features of Sanitary Pipe Fitting

    Rapid Cleaning

    Because the components within the piping system are small and constructed from materials such as plastic or Teflon®, they can be quickly and thoroughly cleaned without damaging or degrading them.

    Different Standards

    There are a number of different standards that cover sanitary fittings, valves, and other components. These include USP 797 for medical tubing fittings and valves, ISO 8115 for vacuum interrupter valves, and ISO 10296, DIN EN 29053 for hose couplings in the food industry.

    Quality

    All manufacturers of sanitary pipe fittings carry out strict quality control to ensure that only components that pass their high standards are allowed to be sold.

    Types of Sanitary Pipe Fitting

    Sanitary pipe fittings are available in various types designed to meet strict hygienic standards in food, beverage, dairy, and pharmaceutical industries. Common types include elbows, tees, reducers, clamps, ferrules, and unions, which help change flow direction, connect different pipe sizes, and allow quick assembly or disassembly. These fittings feature smooth, polished internal surfaces to prevent bacterial growth, ensure easy cleaning, and provide leak-free, contamination-free fluid transfer.

    Flanges

    Flanges are a joining method used to connect pipes, valves, pumps, and other equipment in a processing plant. They are the second most common joining method after welding.
    Flanges are popular due to the ability to dismantle them for ease of cleaning. They can be welded onto surfaces or screwed in place.
    A flanged joint usually consists of flanges, gaskets, and bolts. The holes on the outside of the flanges are used for bolting them together. The middle of the flange can either be welded or threaded.
    Gaskets such as those used in tri-clamp fittings are used to seal the mated flanges to make them leakproof.
    Flanges can withstand high pressure hence their use in manufacturing but care has to be taken when installing them since most leaks and fire hazards happen at flange joints. Follow the manufacturer’s instructions to a T and use them only for the specifications they were intended.

    Gaskets

    Gaskets are ring-shaped seals used to leakproof flange joints and other mating surfaces. They’re designed to withstand different types of temperatures and pressures, and when properly fitted, they are excellent sealants.
    A common mistake is to overly tighten flange joints and other mating surfaces that use gaskets. This has the effect of putting too much pressure on the gasket and consequently destroying it.
    Gaskets used in brewing are normally made of rubber specially designed for food-grade processors such as nitrile and EPDM.
    Our tri-clamp fixtures use gaskets for sealing which range in OD from ½” to 12”. Our Buna (Nitrile) and EPDM gaskets are ideal for brewing and are both FDA-approved.

    Elbows

    Elbows are fittings that are used to change the direction of a pipe by a 45° or 90° angle. As the name suggests, they look like elbows and make elbow-like joints on the connected pipes. Unlike elbows, their edges are tapered off to ensure that they can’t form pockets where bacteria and product residue can hide. This makes cleaning easier.
    They’re made from different materials such as brass, PVC, stainless steel, copper, etc. Those used in brewing are made of stainless steel due to ease of cleaning and the fact that stainless steel is not easily corroded.
    We have a range of elbows in both 90° and 45°. They can be butt-welded in place such as the 90° Butt-Weld Elbows (2WCL) and the Butt-Weld 90° Sweep Elbows. We also have some that use tri-clamp fittings such as the 45° Tri-Clamp Elbow (2KMP).

    Unions

    Unions are alternatives to flanges and are used in low-pressure smaller diameter piping systems to connect two pipes. They are easier to dismantle than flanges making them ideal for pipe connections that need constant disassembly for cleaning.
    They consist of three parts namely a male end, a female end and a nut. They can be either threaded or socket welded. When male and female ends are connected they provide the required sealing making them leakproof.
    We have some union products such as Union Hexagonal Nuts, Short Plain Bevel Seat Ferrules, and Long Plain Bevel Seat Ferrules.

    Tees

    Tees are a three-way fitting with a 90° branch in the middle. They’re used to collect or distribute fluid from a run pipe and are usually short pipes such as the Tri-Clamp Short outlet Tee (7MPS). They are connected to pipes through butt welding, using gaskets, or threading.
    Tees come in three types:
    Straight tee. The diameter of the branch pipe is usually the same as that of the run pipe.
    Reducing tee. The branch pipe has a smaller diameter than that of the run pipe. The Tri-Clamp Short Reducing Tee (S7RMPS) is an example of this kind of tee.
    Wye. A type of tee pipe that has a 45° branch off instead of 90°. A wye allows pipes to be connected at a 45° angle which is ideal for reducing friction and turbulence. We have two types of wyes namely the Tri-Clamp True Wyes (28BPM) and Sanitary Butt-Weld True “Y” (28W).

    Cross

    This is a four-way pipe fitting that comes in two types: One with an inlet and three outlets, the other with three inlets and one outlet.
    It looks like a cross, as the name suggests.
    The ends can either be socket welded or threaded for fitting to connecting pipes.
    They are ideal for low-pressure and low-temperature environments such as pharmaceutical industries since their design already stresses the fitting and the connecting pipes.
