JIS G3302 Grade SGH340 Hot Rolled Galvanized Steel Pipe for Sale

SGH340 Galvanized pipe

SGH340 Galvanized pipe refers to a steel pipe that has been coated with a layer of zinc on its surface. Galvanizing is a cost-effective and efficient method used for rust prevention, with approximately half of the world's zinc production being utilized for this process.

The purpose of galvanized steel pipe is to protect the surface of the steel pipe from corrosion and extend its service life. A layer of metallic zinc is applied to the surface of the steel pipe, resulting in what is known as a galvanized pipe.

SGH340 Galvanized pipe possesses the following general characteristics:

1. Surface Condition: The surface state of galvanized pipes varies depending on the treatment methods used during the coating and plating process. These include ordinary spangle, fine spangle, flat spangle, non-spangle, and phosphating surface. German standards also specify surface grades.

   
   

2. Appearance: Galvanized pipes should have a visually appealing appearance and must not possess any defects that could hinder their usage, such as lack of plating, holes, cracks, excessive plating thickness, scratches, chromic acid dirt, white rust, and so on.

SGH340 Galvanized pipe finds a wide range of applications due to its excellent properties and durability. Here are some key areas where SGH340 Galvanized pipe is commonly used:

1. Oil and Gas Industry: SGH340 Galvanized pipe is extensively utilized in the oil and gas industry for oil well pipes and oil pipelines. Its corrosion-resistant properties make it ideal for withstanding harsh environments, including offshore oil fields.

   
   

2. Chemical Industry: In the chemical industry, SGH340 Galvanized pipe is widely employed as oil heaters and condensers in chemical coking equipment. The galvanized coating provides effective protection against corrosion from chemical substances.

   
   

3. Construction and Infrastructure: SGH340 Galvanized pipe is commonly used in construction projects for various applications. It is utilized in plumbing systems, water supply networks, and drainage systems. The galvanized coating ensures long-lasting performance and prevents rusting.

   
   

4. Agricultural Sector: SGH340 Galvanized pipe is extensively used in agricultural applications. It is employed in irrigation systems, greenhouse structures, and livestock enclosures. The galvanized coating protects the pipe from corrosion caused by exposure to moisture and agricultural chemicals.

   
   

5. Structural Support: SGH340 Galvanized pipe is also utilized in structural applications. It is used for the construction of scaffolding, handrails, and support beams. The galvanized coating provides added strength and protection against corrosion.

   
   

6. Transportation: SGH340 Galvanized pipe is utilized in the transportation industry for manufacturing railings, guardrails, and signposts. The galvanized coating ensures durability and resistance to corrosion, even in outdoor environments.

In summary, SGH340 Galvanized pipe finds extensive applications in the oil and gas industry, chemical industry, construction, agriculture, structural support, and transportation. Its corrosion-resistant properties and durability make it a reliable choice for various industries.
