DISTINCTIVES FEATURES

A) The External surface is shot-blasted (Sa 2 1/2) by removing millscale and rust, obtaining metal surface to facilities the adhesion.
B) The pipe is heated in a electric or gas oven at a controlled temperature.
C) The adhesive is then applied by hot meit or copolymer. It binds the polythylene to the steel.
D) Immediately afterwards, the extruded polyethylene/polyprophylene is coated on the pipe.
E) After application of the polyethylene/polyprophylene, the pipe is coated by spraying water.

Q: What is the difference between internal and external coating for steel pipes?: A protective layer is applied to the inner surface of steel pipes, which is known as internal coating. The main purpose of this coating is to prevent corrosion and enhance resistance against chemicals present in the fluid being transported. Techniques like spraying, brushing, or dipping are commonly used to apply the internal coating, and it can be made of materials such as epoxy, polyurethane, or cement mortar. On the contrary, external coating involves the application of a protective layer on the outer surface of steel pipes. The main objective of this coating is to protect against environmental factors like corrosion, abrasion, and impact. External coatings are usually applied through methods like wrapping or coating with materials such as polyethylene, fusion-bonded epoxy, or asphalt enamel. To summarize, the primary difference between internal and external coating for steel pipes lies in their location and purpose. Internal coatings safeguard the inner surface from corrosion and chemical attacks, while external coatings provide protection against environmental damage on the outer surface. Both types of coatings are essential to ensure the durability and reliability of steel pipes in various applications.

Q: Are steel pipes suitable for underground industrial waste disposal?: Yes, steel pipes are generally suitable for underground industrial waste disposal. Steel pipes are durable, resistant to corrosion, and can withstand high pressure, making them a reliable choice for transporting and disposing of industrial waste underground. Additionally, steel pipes have a long lifespan and can be easily maintained, reducing the risk of leaks or contamination.

Q: Can steel pipes be used for sewage treatment plants?: Yes, steel pipes can be used for sewage treatment plants. Steel pipes are commonly used in sewage treatment plants due to their durability, strength, and resistance to corrosion. They can efficiently transport wastewater and withstand the harsh chemical environment found in sewage treatment facilities.

Q: Can steel pipes be used for scaffolding and support structures?: Yes, steel pipes can be used for scaffolding and support structures due to their high strength, durability, and versatility. Steel pipes are capable of bearing heavy loads, providing stability and safety in construction projects. They are commonly used in the construction industry for scaffolding, temporary support structures, and as a framework for various building applications.

Q: What are the different types of steel pipe end connections?: There are several types of steel pipe end connections, including threaded, welded, flanged, grooved, and compression fittings.

Q: What are the different types of connections used with steel pipes?: The different types of connections used with steel pipes include threaded connections, welded connections, and flanged connections.

Q: Water, gas, steel pipes, thick steel wire means?: Thick steel wire pipe is the same wire pipe, but the wire pipe is thin tube, easy to damage, so with thick as the outer diameter can protect the wire tube, so called thick steel wire pipe.

Q: How are steel pipes used in the manufacturing of fire sprinkler systems?: Steel pipes are commonly used in the manufacturing of fire sprinkler systems due to their durability, strength, and resistance to high temperatures. These pipes are used to transport pressurized water or fire retardant throughout the sprinkler system, ensuring quick and effective fire suppression. The steel pipes are installed strategically throughout the building, delivering water to sprinkler heads that are activated when heat is detected. Overall, steel pipes play a crucial role in the safe and efficient operation of fire sprinkler systems, protecting lives and property from the devastating effects of fires.
