R&M Energy Systems’ announces new Positive Closure for Oil and Gas Industry. Positive Closure uses the fluid pressure in the pipeline or vessel to secure the door of the hub. The sealing force increases with the increase in fluid pressure for a secure, effective, safe seal, every time. It utilizes only the amount of force needed to secure the door, even under varying pressure conditions or at times when there is no internal fluid pressure at all. Other pipeline closures have locking mechanisms that most often exceed the pressure force in order to prevent the fluid from leaking into the environment. This is unnecessary with Positive Closure which offers fast, easy, safe, secure and economical accessibility to pipelines and vessels. www.rmenergy.com
