Knowledge of carbon steel butt welding elbow

Enhance the corrosion resistance of carbon steel butt welding elbow in the original performance medium, especially the resistance to chloride partial etching, enhance the high temperature performance of austenitic stainless steel tee, and enhance the strength and quenching reliability of carbon steel butt welding elbow. Enhanced the reliability of passivation film, so that stainless steel has a stronger corrosion resistance.

Elbow does not touch the water factor

Carbon dioxide is a debris in water that appears in a combined form under normal standards. Large quantities of bicarbonate in water also appear as free carbon dioxide at low pH standards, so the problem of uniformity of carbonic acid appears.

Therefore, the more carbon dioxide in the water, the more H+ is converted, the lower the pH value of the water, the acidic etch water, the damage to the protective film generated by the surface layer of carbon steel, resulting in carbon steel etch.

If carbon dioxide is added to the dehydrated water, the electricity transfer rate of the water will be increased, and the erosion will be increased.

Therefore, the brine tank should have countermeasures to avoid the dissolution of carbon dioxide into the tank, such as using nitrogen or other rare gases to protect the area above the tank to avoid the destruction of pure water by carbon dioxide.

Carbon dioxide is a relatively common substance in the air, carbon dioxide molecules are made of two oxygen atoms and one carbon atom according to chemical bonds

At room temperature, it is odorless gas, denser than gas, it can dissolve in water, and react with water to transform into carbonic acid. It is not compatible with combustion. The trapping of solid carbon dioxide, commonly referred to as dry ice, is not considered a major contributor to the greenhouse effect.

Application range and determination method of welding elbow

At present, the welding elbow has been able to meet the automated process of mass production, and the construction effect is relatively stable. The existing elbow joint materials have certain design standards, which can meet the current butt manufacturing effect.

The selection of butt welding materials that meet the requirements often pays more attention to the metal properties of stainless steel, which makes the design and forging effect more stable. It is suggested that structural principles should be considered when selecting such materials for design. This can improve the surface effect of the elbow.

The above is to share with you why carbon steel butt welding elbow can not be soaked with water elements, welcome to discuss more about the knowledge of pipe fittings

I hope that according to the above content, we can have a further understanding and understanding of the factors that can not contact water with carbon steel butt welding elbows, and also help people in need
