1inch GROOVED DUCTILE IRON FIRE PROTECTION BUTTERFLY VALVE

Company profile

The company is located in a beautiful coastal city of Qingdao, Shandong Province, China. The company was established in 2015, which is not long, but our technicians have been engaged in the pipeline industry for 20 years.

The company's products will be introduced below. The company is mainly engaged in plumbing systems. Often used in coal mine face, oil, Marine ships and so on. Pipe system includes components: special process corrosion resistant steel pipe, steel pipe coupling, gate valve, pipe fittings (positive tee, elbow, diverter, accumulator, diverter, etc.).

Both steel pipes and components are connected through grooves. I know that many countries continue to use flange connections. We use the groove connection compared to the flange covers less area, the installation of bolts and nuts are reduced, the use of the groove connection can withstand greater pressure.

We mainly develop and produce remote liquid supply systems.  The longest distance project I have done is 6000 meters.  The company has a cost-saving corrosion resistant steel pipe processing technology.  The company self-made stainless steel pipe, through a series of operations to make the stainless steel pipe and the inner wall of the machine completely fit.  This can not only meet the corrosion resistance requirements of the same grade of stainless steel, but also meet the requirements of the same pressure of the steel pipe.  Greatly save costs, save raw materials.  Grooves are machined at both ends of the steel pipe, and the connection between the steel pipe and the steel pipe and the fitting is connected by a grooved coupling.

Advantages

1.Safety performance: 

Groove connection mode, automatic precision casting or precision forging forming, high dimensional accuracy, excellent physical properties, safer use.

2.Weight reduction: 

The same 89 mm connector can reduce the weight by 50% compared to the flange connection.

3.Save time:

The number of bolts and nuts in the grooved steel pipe connector is reduced compared with the flange, greatly reducing the installation steps.

4.Space saving:

No flanges take up less space, and more pipes can be installed in the same space.

5.The price is good:

Products are sold directly from manufacturers to customers, reducing middlemen to earn the difference.

6.One-stop service:

About the pipeline products customers can buy all in our company, no need to look around.
