Qingyun Hongsheng Machinery Parts Co., Ltd. is one of the most reliable manufacturers and suppliers of anti-corrosion lined ptfe composite pipeline in China. We warmly welcome you to wholesale high quality anti-corrosion lined ptfe composite pipeline at low price from our factory. If you have any enquiry about quotation, please feel free to email us.
Product Overview
Our PTFE-lined anti-corrosion composite pipe features a high-quality carbon steel or alloy steel outer shell, lined internally with a layer of high-purity PTFE through advanced processing technology. 
The pipe body is manufactured using precision casting or welding techniques to ensure structural strength and dimensional accuracy. The PTFE lining is applied through specialized processes such as winding, hot pressing, or isostatic molding, ensuring tight integration with the steel body to form a seamless, gap-free protective layer.
The product utilizes premium PTFE resin raw materials from renowned domestic and international brands, and the lining process is mature and reliable, guaranteeing a dense, uniform lining with strong adhesion. This PTFE-lined steel pipe combines the strength of metal piping with the exceptional corrosion resistance, high/low temperature tolerance, and non-stick properties of PTFE. It is widely used in demanding applications such as chemical, pharmaceutical, and metallurgical industries for transporting corrosive media, providing a safe, durable, and cost-effective anti-corrosion solution.
Product Features
Our pipeline achieves superior protection by integrating a robust metal shell with a high-purity PTFE liner. The PTFE lining offers near-inert chemical properties, capable of resisting corrosion from most strong acids, alkalis, and organic solvents while ensuring media purity. The high-quality carbon or alloy steel outer layer provides excellent mechanical strength and pressure resistance, enabling reliable performance under complex operating conditions and sustained physical stress. This "combination of rigidity and flexibility" ensures long-term structural safety and extended service life for the entire piping system.
Advanced Manufacturing & Long-Term Reliability
We employ specialized lining processes such as winding, hot pressing, or isostatic molding to ensure a dense, seamless, and uniform PTFE layer that bonds securely with the steel body. This eliminates risks of lining detachment or media penetration. Through stringent quality control at every stage, from raw material selection to manufacturing, we guarantee product consistency and high reliability. The pipeline maintains stable performance across extreme temperatures (-196°C to +250°C) and harsh corrosive environments, significantly reducing maintenance costs and operational risks for safe and economical long-term operation.

Everything You Need to Know
What specific chemicals can the PTFE lining withstand?
It can resist the vast majority of strong acids (such as sulfuric acid, hydrochloric acid, nitric acid), strong alkalis, organic solvents, halogens, and oxidizers. Specific compatibility requires final confirmation based on the concentration and temperature of the medium, along with a detailed compatibility list.
What are the maximum and minimum operating temperatures of the product?
The standard product's continuous operating temperature range is -196°C to +250°C. For short-term peak temperatures, please consult our engineers.
Will the lining layer detach? How is the bonding reliability ensured?
We employ a unique winding and hot pressing or isostatic molding process, which creates a tight mechanical bond and expansive fit between the PTFE lining and the inner wall of the steel pipe. This eliminates the risk of "ballooning effects" or detachment that may occur with cold sleeving methods. The entire process is subject to strict quality control.
Can fittings such as elbows, tees, and reducers be produced?
Yes. We provide a full range of PTFE-lined fittings (elbows, tees, reducers, etc.) compatible with straight pipes, ensuring the corrosion-resistant integrity of the entire pipeline system.
