For businesses involved in oil, gas or chemical transfer, no matter how limited the extent, new and existing pipe networks should be checked observe they meet the highest standards for secure containment. One of the main concerns is that many existing pipe networks, as wll as many pipe fittings that you can purchase today, are made from carbon steel.
Carbon steel has many uses in the transfer of non-hazardous materials in normal external atmospheric conditions (in sprinkler systems for example). It is however highly susceptible to corrosion, particularly from harsh atmospheric environments such as brine. Additionally, carbon steel is more difficult to repair or cap using welds since, in its strongest formations, it is both highly heat resistant and less ductile than other steels.
An additional issue with existing networks can be the poor quality from the pipe connections or of the pipe flanges used to secure those friendships. Not only can flanges also be made out of the same corrosion-susceptible carbon steel, in some instances the pipes certainly not fitted securely from your flange. The resulting weakness in rest and memory connect again makes the network more liable to corrosion.
Replacement of pipe fittings and pipe flanges with those made from an increasing secure stainless steel product is always highly recommended for oil, gas and chemical transfer. Austenitic stainless steel or the even more corrosive-resistant superaustenitic stainless steel may be the most suitable, depending using the substance being moved. These are both also straightforward to weld.
The alternative low-weight-to-strength ratio alloys of duplex and super duplex steels also perform well, and employing these confers the advantage of being placement to install much more lightweight pipe fittings. When it comes to securing pipe connections, ANSI-standard butt weld fitting pipe flanges are strongly recommended
At ChemiPetro a number of advise on the suitability of both new and existing pipe networks, and provide any necessary alternative fittings.
