History of the development of hot-dip galvanizing

 Hot dip galvanized (galvanizing), also known as hot-dip galvanized and hot-dip galvanized: it is an effective anti-corrosion of the metal, mainly used in the metal structure of the industry facilities. The rust steel immersed in liquid zinc melt around 500 ℃, steel members attached to the surface of the zinc layer, which play the purpose of anti-corrosion . Hot-dip galvanizing process: finished pickling - washing - plus help the bath - drying - hang plated - cooling - Pharmaceutical - cleaning - polishing - hot galvanized completion. Corossion is one of the chronic metal disease that destroys the metals gradually.

The hot-dip galvanizing is evolved by ancient Redu, has 140 years of history since 1836, France had been used in industrial hot dip galvanized. However, hotdipped galvanized steel pipe manufacturer in the past three decades along with the rapid development and large-scale development of the cold-rolled steel strip. Galvanizing process not only makes metal an anti corrosive but helps in providing strength as well as increases the life span of metals.

ASTM PIPE

What is ASTM? ASTM Standards! Development of standards!

 Services of ASTM International. Use of standards. Annual book of ASTM 

 

 These ASTM standards define the specific manufacturing process of the material and determine the exact chemical composition. Most of hot dipped galvanized steel pipe manufacturer keeps this standard for fittings and flanges, through percentages of the permitted quantities of carbon, magnesium, nickel, etc., and are indicated by "Grade".

 For example, a carbon steel pipe can be identified with Grade A or B, a stainless-steel pipe with Grade TP304 or Grade TP321 etc..
Below you will find as an example a table with chemical requirements for fittings ASTM A403 Grade WP304, WP304L, WP316L and a table with frequent Grades, arranged on pipe and pipe-components, which belong together as a group.

Corrosion (Rust) - A Chronic Disease

Corrosion is a one of the chronic gradually attacks and inlay destroys metals life. Like any other chronic disease the old adage applies; announce of prevention is worth a pound of cure. A process known as oxidation is the major cause of Corrosion. In oxidation process oxygen combines with moisture and oxide to form Corrosion (Rust). Corrosion can be protected through a process know as  Hot Dip Galvanizing process.

                                                                     

Disadvantages of Corrosion:

Corrosion

• When Iron oxide gets mixed it leads to the gradual weakening of the metal bonds that leads to gradual destruction of metals life.
• Corrosion is the main cause that leads to shortening of the metals life.
• It is the one of the factor that leads to enhancement of maintenance cost of metals.
• It leads to the gradual loss of metal bonds integrity and metal surfaces.
• It is one of the leading factors in destroying the value of metal objects.

Prevention is better than cure

Hot Dip Galvanizing Process

A process known as Hot Dip Galvanizing is one of the most effective technique of avoiding Corrosion (Rust). In this process in which a protective layer of zinc is coated on the metals which Is the anti corrosion (rust) element eventually it provides long term strengthening of metal bonds. It leads to enhancement of metals life. Now a day’s hot dipped galvanized steel pipe manufacturers are using galvanized steel throughout the world in the area of building construction, transportation, agriculture sector and electric power etc.
