What is the Testing Procedure for Pipe Fittings?

Stainless steel pipe fittings are used to connect steel pipes. Tapered threads are cut into the end of the pipe, sealant is applied in the form of thread-sealing compound or thread seal tape (which is also known as PTFE or Teflon tape), and a pipe wrench is used to thread the pipe into a threaded fitting. Stainless steel fittings benefit from the metals strength, resistance to corrosion and ease of cleaning. We at Rajveer Stainless and Alloys are well known as Pipe Fittings Manufacturers in India designed as per the required standards.

 

Typical methods for manufacturing seamless stainless steel tubing are by extruding, gun drilling or piercing.  However, the extrusion process provides the most uniform OD (outside diameter) and ultimately the most concentric ID (inside diameter).  In addition, extrusion is the only process most suitable for long length seamless stainless steel coil tubing.

Stainless steel pipe fittings are often used in buildings to convey natural gas or propane fuel, or in plumbing systems. They are a popular choice in fire sprinkler systems due to their resistance to mechanical damage and intense heat. Stainless steel solder fittings are used in many industries, including those which require pipes and fittings to transport and come in contact with food, beverages, or other products, and thus have strict hygiene practices. These include the food, dairy, brewing, biotechnology, pharmaceutical and chemical industries.

Stainless steel buttwelding fittings, includes elbow, tee, reducer, stub end, end-cap etc. The dimension is up to NPS 104″ and wall thickness SCH5S, 10S, 40S, 80S, XXS etc. Solder fittings, also known as capillary fittings, are short sections of smooth pipe designed to slide over the outside of the mating tube. Solder wire is fed then around the edge of the fitting and heated to seal it. Stainless steel solder fittings benefit from the metals strength, resistance to corrosion and ease of cleaning.

 

Testing of the fittings

After the tube is fully formed to the desired specification it is hydrostatically tested to ensure integrity.  Hydrostatic testing determines and verifies the tubing meets the specification.  Several types of information can be obtained through this verification process.  Key inspection data can be identified through the hydrotest process, such as: Material flaws, Mechanical properties, Specific hard spots that can fail when hydrogen is present, Finishing, Stainless steel coil tubing can be level wound on spools for shipment or straightened and cut to specific lengths designated by the customer, Products can be polished and stenciled with pertinent information for lot traceability and manufacturing identification.

We are high quality Pipe Fittings Manufacturers in India. Our fittings are made through a section of a seamless metal sheet, hot worked and then cold finished to obtain the acceptable shape. They are opposite of Welded fittings, Monel seamless fittings are devoid of the weld seam produced by welded fittings, thus these fittings are more pressure bearing and do not crack under extreme load. Our Pipe Fittings do not crack or fail under high temperatures are strong and reliable and permit greater design freedom.
