Recently, Jiangsu RANA Fluorine Materials Technology Co., Ltd. (hereinafter referred to as RANA Company), leveraging its profound R&D expertise in fluorine materials and sustained innovation capabilities, has successfully developed high-performance PTFE lined piping specially designed for pipeline connection in confined spaces. Featuring flexible customized length, outstanding corrosion and high-temperature resistance, and an advanced pipe drawing & flanging process, the product perfectly meets the flange connection requirements of core equipment in chemical, pharmaceutical and other industries. It delivers an efficient, stable and brand-new safe solution for medium transportation under harsh working conditions, marking a new milestone in China’s high-end fluorine-lined pipeline technology.
In modern chemical and pharmaceutical production scenarios, connecting pipelines for core equipment such as reaction kettles and liquid mixing tanks are constantly confronted with multiple challenges: narrow installation space, diversified interfaces, highly corrosive media and drastic temperature fluctuations. Conventional pipelines suffer from poor adaptability, corrosion and leakage, high flow resistance and excessive energy consumption. Focusing on such industry pain points and drawing on years of accumulated fluorine lining technology, RANA has achieved comprehensive breakthroughs in both design and craftsmanship for this newly developed PTFE lined piping, perfectly catering to installation and application demands in compact spaces.
At the core craftsmanship level, the product adopts Ruineng’s self-developed pipe drawing & flanging technology, which underpins its superior performance. During production, high-quality PTFE tubing is tightly drawn into the metal base pipe via precise mechanical tension, followed by professional thermal treatment for flanging forming. Strict stress relief procedures are then implemented to ensure seamless and integrated bonding between the PTFE lining and metal substrate.
This advanced process completely eliminates common defects of traditional lined pipelines such as lining hollowing, wrinkling and peeling. The inner wall of the pipeline achieves an ultra-smooth finish without any dead corners or folds. Professional tests verify that it can reduce medium flow resistance by over 15%, substantially cutting transportation energy consumption and improving production efficiency. Meanwhile, it avoids medium residue and cross-contamination, making it particularly suitable for the transportation of high-purity and clean media.
The product’s core advantages lie in exceptional strong corrosion resistance and superior high-temperature resistance. PTFE itself features extreme chemical inertness, enabling long-term resistance to erosion from strong acids, strong alkalis, strong oxidants, organic solvents and other highly corrosive media, fundamentally eliminating potential safety hazards such as pipeline corrosion perforation and medium leakage.
Furthermore, optimized with special formulations and enhanced craftsmanship, the product boasts remarkable high-temperature resistance, maintaining stable physical and chemical properties over a wide temperature range. It is fully applicable to high-temperature medium transportation for chemical reaction kettles, pharmaceutical liquid mixing tanks and similar equipment, solving the industry pain point of ordinary pipelines prone to aging and failure under high-temperature and strong corrosion environments.
In terms of design adaptability, this PTFE lined piping is fully optimized for installation in confined spaces with flexible customized length. It can be precisely adjusted according to on-site actual dimensions without additional splicing or modification, greatly shortening the construction period and lowering installation costs. In addition, standardized flange interface design enables seamless compatibility with mainstream equipment flange specifications, offering high versatility and wide applicability. It can be quickly installed for both new projects and old equipment renovation, greatly enhancing the flexibility of pipeline design and construction.
Stringent quality control guarantees long-term stable operation of the product. RANA has established a full-process quality inspection system. Before delivery, each batch of this PTFE lined piping undergoes rigorous multi-round high-standard tests including pressure testing, tightness testing and corrosion resistance testing, fully simulating service conditions under extreme working environments. This ensures sustained stable operational performance even under harsh conditions of high pressure, high temperature and strong corrosion, eliminating safety risks and safeguarding enterprises’ safe production.
As a high-tech enterprise deeply engaged in the fluorine materials industry for years, RANA always takes technological innovation as its core driving force. It specializes in the R&D and production of high-purity fluororesin lined equipment and pipeline fittings, holding a number of independent intellectual property patents. Its products are widely applied in petrochemical, pharmaceutical, environmental protection, electronics and other fields, winning high recognition and trust from domestic and overseas customers with reliable quality and professional technical services.
The successful development of the compact PTFE lined piping represents another important achievement of RANA in responding to industry demands and adhering to technological innovation. Going forward, RANA will continue to deepen its layout in the fluorine material anti-corrosion sector, increase investment in R&D, and launch more high-performance and high-reliability innovative products. It will support the green development of chemical and pharmaceutical industries with higher safety, efficiency and environmental friendliness, and contribute to the domestic substitution process of high-end anti-corrosion equipment in China.
