Zhejiang Daye Flange Co., Ltd. is one of the leading manufacturers and suppliers of 316l stainless steel paddle spacer in China. With abundant experience, we are committed to providing high quality flanges made in China with competitive price. We warmly welcome you to buy durable 316l stainless steel paddle spacer in stock here from our factory. Also, quotation is available.
Paddle Spacer is frequently used together with paddle blank. Similar in structure to the paddle blank, it has a central round bore. Normally, it is installed between flanges after the paddle blank is removed to ensure normal medium flow in the pipeline.
Paddle spacers are widely applied in oil, chemical and other piping lines, especially under service conditions requiring frequent maintenance, inspection and replacement.
Stainless steel paddle spacers are commonly used. Grade 304 is a cost-effective stainless steel material, whereas 316L stainless steel paddle spacer features outstanding chloride-resistance and performs well in chloride-containing media such as seawater.

Product Advantage
Visual status identification
The exposed handle of the paddle spacer features a small indicator hole, enabling clear judgement of pipeline open or closed status.
Excellent flow performance
Full‑bore design without flow restriction, low risk of impurity accumulation.
Applications
Pipelines with low switching frequency
Paddle spacer is applied for long‑term flow service; single blind plate is used during major overhaul.
Service conditions where spectacle blind is not practical for installation.

FAQ
Q: What are the differences between a paddle spacer and a spectacle blind?
A: A spectacle blind is an integrated combination of single blind plate and paddle spacer, offering more convenient operation. However, when pipelines are in confined spaces where there is insufficient room for spectacle‑blind rotation, separate paddle spacers and single blind plates are more suitable for installation.
To sum up, spectacle blinds are preferred for pipelines with ample operating space and frequent switching requirements; they are also easier for storage.
Q: Can paddle spacers only be used temporarily?
A: No. paddle spacers can serve in pipelines for long-term operation. They are used together with single blind plates only when pipeline isolation is required.
Q: Are 316L Stainless Steel paddle spacers widely used in practical applications?
A: Usage varies by industry. Carbon steel remains the most widely used material. Nevertheless, 316L Stainless Steel paddle spacers are commonly adopted under corrosive service conditions. For fresh water and dry gas services, 304L delivers better cost-effectiveness.
Q: What is the MOQ?
A: We don't have MOQ,but the more quantity,the price lower.
Q: What are your payment terms?
A: Perfer TT,L/C also acceptable.
Q: What surface finish do you provide?
A: 125-150AARH/,we can also customize accoding to your requirements.
