Certification
All materials are strictly inspected at every stage of the production process from procurement to product shipment. Visually inspect them for compliance with ASTM, ASME, MSS, DIN, EN and JIS codes and standards. Support officially certified inspection agencies to witness product material reporting, dimensional and quality compliance. Factory inspections are also supported.
Product Description
Threaded flange is a type of flange that uses threads to connect with pipes. When designing, it can be treated as a loose flange. The advantage is that welding is not required, and the additional moment produced on the cylinder or pipe when the flange is deformed is very small. The disadvantage is that the flange thickness is large and the cost is high. It is suitable for the connection of high-pressure pipeline.
Threaded flange also known as screwed flange, is a kind of non-welding flange that the inner hole of the flange is processed into pipe thread and matched with the pipe with thread to realize the connection. It is compared with flat welding flange or butt weld flange, threaded flange has the characteristics of easy installation and maintenance, and can be used in some pipelines where welding is not allowed on site. Alloy steel flange has enough strength, but not easy to weld, or welding performance is not good, can also choose threaded flange. However, under the condition that the temperature of the pipeline changes drastically or the temperature is higher than 260℃ and lower than -45℃, it is recommended not to use threaded flanges to avoid leakage.
Due to the stainless steel flanges, carbon steel flanges, alloy steel flanges, plate flanges, butt welding flanges, anti-corrosion flanges, ring flanges, blind flanges, etc. provided by our company have high standards, good materials, and many specifications , we are able to undertake many large, medium and small projects, coupled with our resolute service attitude that considers our customers, this also allows our customers to have a high repurchase rate.
