Out of all the types of valves used in industrial plants, ball valves are one of the best maintained and simplest to operate. It is no wonder that they are the first pick in oil & gas, chemical industry, water treatment, food processing, and HVAC systems, as their compact size, extremely low torque requirement, straight flow path, and quick shut-off ability allows them to be operated with ease. However, even the most reliable ball valve can run into problems under dire site conditions such as aggressive fluids, dirt, corrosion, and mechanical abuse. Ball valves feature an extremely low failure rate, which is a double edged sword. One of the most common faults maintenance teams make is treating ball valves as fit-and-forget components, forgetting the fact that they provide very distinct signals when they are struggling including erratic flow control and inoperable shut-off.

Difficulty or Hardness in Operating the Handle

One of the foremost challenges

Flanged joints are the most crucial bolted joints in piping systems, be it oil & gas pipelines, chemical plants, power plants or water treatment plants, flanges are everywhere. What most folks in maintenance or operations tend to forget is that no matter how wonderful your flange and gasket are, if your bolts are not adequately torqued, your joint is destined to fail.

When people talk about bolt torque, it is not simply ‘tightening bolts till the time the wrench feels pressured to turn’. It’s purely an engineering matter. The mighty engineering marvel of bolt torque control is the sole reason standing between a leak proof joint or a cataclysm just waiting to happen and in industrial settings, inappropriate torque on flange bolts is one of the major culprits for destruction of spare joints and gaskets.

What Does Bolt Torque Actually Do?

Bolt with the help of their head contains the nut which is fixed on top of the
