minimum change in design. 

Porous metal elements can be integrated into all kinds of fittings for a cost effective solution that guarantee laminar flow in your processes.

By combining two existing products into one, a completely new product was created. How did our engineering department come up with this innovation?  It all evolved by a question of one of our customers in the 
Semiconductor industry already using our fittings. The challenge was to make a cost effective flow restriction in their system with a minimum of change in the current design. This can be done in two ways:

  • Using a component with an orifice. Restriction by a hole in the house of the fitting.

Standard orrifice
Standard Orifice: Speed, pressure and heat increase as gas moves
through the orifice, causing wear and tear.

Flow restrictor

Flow Restrictor: Gas moves uniformly through porous metal element
with minimal friction due to viscosity.

Teesing created a solution for this particular customer by combining an existing fitting with a porous metal element inside to create a laminar flow.

Major advantages

  •  Reduces the flow burden -  from one pore to hundreds
  •  Prevents plugging -  by distributing flow over the entire insert.
  •  Minimum change of design –  same coupling, different functionality.

To identify the best design for your application, it is essential to make sure you know the following parameters:

  1.  Type of gas
  2.  Upstream pressure
  3.  Downstream pressure
  4.  Desired flow rate (positive pressure, ATM or vacuum)
  5.  Fitting (if applicable) a. Type b. Size c. Material

If you want a cost effective solution with optimum laminar flow in your process a porous metal element is the best solution.

Of course this integration of a porous metal element into a fiting can be done with any fitting!
