In the world of construction and industrial materials, high - quality pipes are of utmost importance. Youfa, a renowned name in the industry, offers an exceptional range of products, especially the Youfa National Standard Steel - Plastic Composite Pipes and Lined Plastic Galvanized Coated Steel Pipes, which are customizable with a complete range of specifications.

Youfa was established on July 1st, 2000. Since 2006, it has been consecutively ranked among the top 500 enterprises in the Chinese manufacturing industry for 17 years. With approximately 9000 employees and 293 production lines spread across 13 factories, Youfa is a powerhouse in the steel pipe manufacturing sector. In 2022, the company produced 20 million tons of various steel pipes and exported 300 thousand tons globally, demonstrating its strong production capacity and international reach.

Youfa National Standard Steel - Plastic Composite Pipes

These composite pipes are designed by combining the robustness of steel with the corrosion - resistance and smooth - flow properties of plastic. The base material is high - quality steel, which provides excellent structural integrity and the ability to withstand high pressures. The plastic lining, often made of food - grade polyethylene (PE) or other suitable polymers, is carefully bonded to the inner wall of the steel pipe.

The manufacturing process of Youfa's steel - plastic composite pipes is highly sophisticated. First, the steel pipes are thoroughly inspected for any defects. Then, through a specialized lining process, the plastic layer is uniformly applied to the inner surface. This ensures a seamless and durable connection between the steel and plastic layers. The result is a pipe that not only resists corrosion from various fluids but also reduces friction, allowing for more efficient fluid transportation.

One of the key advantages of Youfa's steel - plastic composite pipes is their wide range of applications. They are extensively used in the construction of water supply systems, both for domestic and industrial purposes. In domestic water supply, the food - grade plastic lining ensures that the water remains clean and free from contaminants, meeting the highest standards of hygiene. In industrial settings, these pipes can handle a variety of fluids, including chemicals, due to their excellent corrosion - resistance properties. They are also suitable for use in heating and cooling systems, where their ability to withstand temperature variations is crucial.

Lined Plastic Galvanized Coated Steel Pipes

Youfa's Lined Plastic Galvanized Coated Steel Pipes are another remarkable product in their portfolio. These pipes start with a galvanized steel base. Galvanization involves coating the steel with a layer of zinc, which significantly enhances its corrosion - resistance. The zinc coating acts as a sacrificial anode, protecting the underlying steel from rust and degradation.

After galvanization, a plastic lining is added to the inner wall of the pipe. Similar to the steel - plastic composite pipes, this lining provides additional protection against corrosion and improves the flow characteristics of the fluids passing through. The outer surface of the pipe can also be further coated with materials such as epoxy resin powder (EP) or polyethylene powder (PE) through a drawing coating process after pre - heating at high temperature. This additional outer coating not only enhances the aesthetic appearance of the pipe but also provides an extra layer of protection against environmental factors.

The production process of these pipes adheres to strict quality control measures. Each step, from the selection of raw materials to the final inspection, is carefully monitored. The zinc coating thickness is carefully controlled to ensure optimal corrosion - resistance, and the plastic lining is checked for uniformity and adhesion. The products meet the construction standards such as GB/T 28897 - 2012, and the inner wall of pipes and fittings complies with 《Hygienic Safety Evaluation of Domestic Drinking Water Transmission and Distribution Equipment and Protective Materials》(2001), ensuring that they are safe for use in potable water systems.

Customization and Range of Specifications

Youfa understands that different projects have diverse requirements. That's why they offer customization for both the steel - plastic composite pipes and lined plastic galvanized coated steel pipes. Whether it's a special diameter, wall thickness, or a specific combination of materials, Youfa's advanced manufacturing facilities and experienced engineering team can meet the demands. They can produce pipes with diameters ranging from small sizes suitable for residential plumbing to large diameters required for industrial and infrastructure projects. The wall thickness can also be adjusted according to the pressure and load requirements of the application.

Moreover, Youfa can provide pipes with different surface treatments based on the customer's needs. For example, in addition to the standard galvanized and plastic - coated options, they can offer pipes with 3PE (three - layer polyethylene), FBE (fusion - bonded epoxy), or 3PP (three - layer polypropylene) coatings for enhanced corrosion - protection in harsh environments. These coatings are particularly useful in applications such as oil and gas pipelines, where the pipes are exposed to aggressive chemicals and environmental conditions.

In conclusion, Youfa's National Standard Steel - Plastic Composite Pipes and Lined Plastic Galvanized Coated Steel Pipes, with their customizable features and comprehensive range of specifications, are ideal choices for a wide variety of construction and industrial applications. Backed by Youfa's strong reputation, advanced manufacturing capabilities, and commitment to quality, these pipes offer reliability, durability, and performance that customers can trust. Whether it's a small - scale renovation project or a large - scale infrastructure development, Youfa has the right pipe solution to meet the needs.
