The protection measures of broad ocean hardware for stainless steel pipe fittings.

1. Start with the material of stainless steel elbow pipe, and strictly control the quality of raw materials.
The stainless steel elbow pipe and pipe bending pipe fittings are strictly inspected.
To ensure that the material meets the requirements.
On select material from two aspects of economy and function of comprehensive consideration, under the special operating condition, can consider to choose stronger corrosion resistance ability of high nickel austenitic stainless steel pipe bending, duplex stainless steel pipe, titanium and titanium alloy, glass fiber reinforced plastic, etc.
When selecting material, increase the corrosion margin of pipe and stainless steel elbow to meet the service life of piping system.

2. Surface coating protection.
For stainless steel elbow bend pipe corrosion in environment, in addition to select corrosion resistant ability of materials, can also through the surface of stainless steel pipe bending pipe coating coating method for improvement of the ability to resist corrosion.
For stainless steel pipe bending pipe base material surface is smooth, the conventional stainless steel elbow reducer with poor anticorrosion coating on the surface adhesion, currently developed an used in the Marine environment of stainless steel pipe anticorrosion coating, epoxy powder coating.
The coating is a new type of coating which is completely free of solvent and is sprayed into film in powder form.

We produce stainless steel Elbow pipe fittings.

3. Electrochemical protection.
Electrochemical protection methods mainly include protection of protectors, cathodic protection and anodic protection.
(1) protector protection means to connect the metal with low electrode potential to the protected metal to form the original battery.
The metal with a lower electrode potential is dissolved as an anode, and the protected metal is used as a cathode to avoid corrosion.
(2) the cathodic protection method is refers to the additional dc power supply, will be to protect metal from negative electrode as cathode, makes the protected metal stainless steel pipe flange potential negative adjustment, into E - pH figure not corrosion area;
The method of protecting the cathode from the corrosion of the old metal by the anode.
(3) anode protection method is to point to use with dc power supply, will be most anode, protect the metal from the positive electrode potential to the moving direction (i.e., anodic polarization), enter the passivation of E - pH graph area, make the protected metal "passivation" and protected.


In stainless steel pipe bending head material meets the requirements under the premise of high temperature, high humidity and high salt sea breeze, salt fog, sea water splash and other stainless steel pipe bending pipe under complicated Marine environment corrosion reason is mainly caused by chemical corrosion and electrochemical corrosion of chlorine ion.
Can change the way of pipeline surface treatment, corrosion resistance stronger materials, stainless steel pipe bending pipe surface coating or electrochemical protection methods to restrain or eliminate corrosion of stainless steel elbow pipe.
It is hoped that the above methods will be of great help to similar projects in the future.
