RDD Projects

MECESA has a Technical and RDD Department that gives the Company a competitive advantage in the market due to its high capacity of production and its flexibility in the designs. MECESA is constantly developing products in order to fulfill our customer’s needs. Therefore, it is always ready to apply small modifications to standard designs as requested, but also to develop important RDD projects. They have a lot of experience developing new products or adapting standard designs to meet the requirements of an end use product or an EPC project, either by applying special materials, or by giving extra features to a product.

A relevant example of an RDD design is the multifunction assembly shown below

It is an assembly that combines a standard AM 1/4” needle valve, a MC Manifold Valve and a pressure relieve valve set to 280 bar. 1/2” NPT-F inlet and outlet connections. There are two other outlets: one is a 1/4” NPT-F outlet downstream the needle inline valve to connect a pressure gauge, and the other is a 1/2” NPT-F as a drain. In line 1/4” AM Needle Valve function is to open and close the line. IT was necessary to use this valve instead of a manifold valve to be able to meet flow requirements. The MC Manifold Valve is for a manual drain so there is no flow requirement. The pressure relief valve is connected downstream the line valve so it has an automatic drain set to 280bar. This multifunctional assembly is a successful example in which two different Needle Valve’s models are combined with a pressure relief valve similar to the ones MECESA uses for instrumentation PRV. This way, customer requirements are met with a cost-optimized solution by using standard models of valves.


The origins of MECESA’s most important RDD projects are:

• Our current largest and most challenging projects are based on developing entirely new products that give technical solutions to a certain application which is not available in the market. This is possible thanks to our customer’s trust on our experience, professionalism, seriousness and commitment.
• • The other RDD projects are started because of MECESA’s own experience with the existing products in the market and our culture of continuous improvement, which has been one of MECESA’s most important key values for more than 60 years. Among them there is an ongoing project on improving megalok® and be able to use this fittings for other applycations beyond the scope of the standard fittings in the market. Even though these compression fittings are well known for their reliability and quality, we want to take a step further and focus on the improvement of the material treatments and the mechanical properties of all of their components in order to launch new compression fittings that cause no friction and can be used without lubricant.
  
  This project has been co-financed by the European Regional Development Fund (ERDF), within the Operational Programme Smart Growth 2014-2020, with the aim of promoting research, technological development and innovation.
