The Importance of Properly Sealing Threaded Connections for Hazardous Gases and Liquids

0

When storing and transporting cylinders, especially those containing flammable or corrosive liquids and gases, leak-tight seals are of critical importance. As any distributor of packaged gases can attest, a number of problems arise when a cylinder is found to leak.

It can be dangerous to both the customer and those nearby to have a cylinder with a leaking valve. If the leaking gas or liquid is flammable or caustic, it can ignite or explode. In such instances, there is a real potential for injury or even death in addition to equipment and property damage at the customer’s location.

Leaking valves are also costly, not to mention frustrating, to the distributor who supplied them. When it is discovered that a cylinder leaks after delivery to the customer, the distributor has two options. If the cylinder can be easily moved, a truck can be sent to the location to pick up the cylinder and deliver a replacement.  In other cases, however, replacement is not an option. A distributor needs to send someone to the customer’s location to repair a connection that cannot easily be returned to the distributor. In this case, a leaking cylinder is repaired in situ. Both options incur additional expenses for the distributor.

Many distributors are involved with the selling and/or assembling of many different types of gas handling systems. The threaded connections and valves that connect flowmeters, delivery systems, generators, and regulators all have the potential for leaks. As with cylinder valves, if the threaded connections are not properly sealed they may leak in time, creating a possible hazard for the customer’s employees and equipment.
