Coated pipe: it is a steel plastic composite pipe with an outer layer of plastic coating and a metal inner layer of rust prevention layer. The standard diameter is 27.8mm±0.2mm, and the outer layer is PE, ABS and ESD plastic layer.
Coated Pipes, also referred to as Lean Tubes in lean manufacturing systems, offer exceptional durability and adaptability for various industrial applications.
These pipes consist of welded steel with an outer plastic coating and an inner anti-corrosion layer, delivering both strength and versatility.
Let’s trace back to Toyota in the 1990s. Faced with the high costs and inefficiencies of frequent production line adjustments, they developed a groundbreaking solution:
This design not only improved flexibility and scalability but also reduced maintenance costs. The emergence of Coated Pipes became a critical tool in lean production, significantly optimizing work efficiency and resource utilization.
Step 1 – Forming
Compress the steel strip into a round tube using a tube-making machine.
Step 2 – Coating
Use an extruder to apply a plastic coating to the surface of the round tube.
Step 3 – Cooling
Cool the coated tube using an air box and water tank.
Step 4 – Cutting&Packaging
Cut the cooled lean tubes to standard lengths and package them.
We use hardened cold-rolled steel, incorporating internal pipe coating to extend the service life of these corrosion resistant pipes, significantly reducing material loss.
In addition to internal pipe coating, we apply various external coatings to these coated pipes, including PE coatings, ABS coatings, or anti-static coatings, to ensure they function as durable corrosion resistant pipes and meet the requirements of different environments.
We monitor the quality of the entire process, from raw materials to shipment, ensuring that each lean tube meets high standards. For instance, every corrosion resistance tube undergoes gas testing before being wrapped with plastic coating. That's because:
We conduct strict quality control measures on coated anti-corrosion steel pipes and other rust resistant pipe products, coupled with exceptional after-sales service. This commitment has earned us global partners in over 20 countries and regions worldwide.
Yes, we provide customization for lean tubes, including length, color, and thickness. The MOQ (minimum order quantity) is 4,000 meters. Send an inquiry to junliu@szyms.com for detailed consulting on our corrosion resistant pipes and related products.
