Why we have started using marine grade Spray Shields for spray protection in industries?

Stainless Steel Grade 316  or SS 316 is also known as Marine Grade Stainless Steel. Stainless steel creation backdates to 1913 when the great Harry Brearley made a steel with addition of  12.8% chromium and a carbon level of only 24 percent. Stainless steel was made with the sole motivation behind making a climate and corrosive safe steel. One curious property of Stainless steel is it can't be hardened by heat treatment. The presence of extra molybdenum lends SS316 its anti-corrosive properties. Because of its superior mechanical strength & corrosion resistance, it is used in many products including Flange Guards & Safety Spray Shields.

In chemical & petrochemical industries, there are kilometers of pipelines connected by thousands of flanges & threaded joints. These lines carry hot oil & corrosive chemicals like acid at very high pressure. Sometimes, due to mechanical failure, these joints start splashing these liquids in form of spray. In absence of spray shields, This is generally life threatening for any person in the vicinity. 

Loss of life is always catastrophic. The plight of the worker and his family is beyond imagination. The company also suffers both in terms of cost & time. For this reason, industries, government & safety regulators around the world came together and decided to make the use of flange guards & safety spray shield mandatory. Insurance companies have also joined the bandwagon by making Flange Guards necessary for clearance of claims. 

Flange Guards are safety shields designed to be wrapped on flanges, valves & threaded joints. These safety spray shields efficiently contain the splashes & sudden spray-outs thus giving worker enough time to safeguard themselves & take action. Any Flange spray shield works on the principle of pressure diffusion & safe discharge of liquid.

Flange guards made out of SS316 are considered the benchmark in the world for spray safety. Ss316 Flange Protector Bands are made of marine grade stainless steel. These are highly resistant to corrosion & can withstand extremely high temperature for a sustained period of time.  SS316 Safety Spray Shields have multiple layers of mesh on the inside. During an occurrence of a splash, the spray of liquid passes through the many layers of mesh in the spray shield losing its kinetic energy in the process. By the time the spray hits the wall of the flange spray shields, it is completely stripped of its energy & pressure & it is safely discharged. Also, drains nozzles are provided on demand which can be used to drain the splash at a safe location away from the flanges & joints. 

Since spray of flanges & valves is a common event in oil, petroleum, chemical & pharma industries, installation of flange guards have saved a lot of lives. All the industries have welcomed the mandatory installation of flange safety shields & valve guards. In fact, most of the industries are proactively working towards promoting healthy work environment & making their units complete safely. From workers point of view, the presence of metallic spray shields & splash guards keeps him assured. It also sends out a message that the management is caring enough to in flange guards & spray shields. 

 Today industries in African countries have also adopted the use of flange shields & valve spray shields. We are very glad to see the maturity and focus shown on the issue of industrial safety by everyone.
