ASME/ANSI B16.5 Threaded Flange

Carbon Steel Threaded Flange, Stainless Steel Threaded Flange, Alloy Steel Threaded Flange Manufacturer In China

Cangzhou Taichang Pipeline Equipment Co,. LTD  is a specialised manufacturer of high quality ASME/ANSI/DIN/JIS standard threaded flanges or screwed flanges in China. We offer immediate delivery programs for standard size of carbon steel threaded flanges and stainless steel threaded flanges.Threaded flanges are widely used in low pressure piping systems, as no welding is involved while connecting the flanges to pipes or other equipment. However the flange may be welded around the joint after assembly, but it is not considered a satisfactory method of increasing its applications. Threaded flanges are also known as screwed flanges and are similar to slip-on flanges, but the bore is threaded to enable assembling without welding. Threaded pipe flanges are usually used with pipes that have external threads.
We offer threaded pipe flanges manufactured at our facility to companies in various industries including shipbuilding, power generation petrochemical plants, oil refineries waste water treatment plants, paper mils, pharmaceutical plants and turnkey proects among others.
Our products are widely exported to countries and regions such as the United States, Europe, Russia, Turkey, Malaysia, the UAE Saudi Arabia, lran, Brazil Chile Mexico, South Africa, jordan, Tunisia, Vietnam, Indonesia, Thailand, Singapore, Colombia, and Sri Lanka.

Marking & Packing

Products are packaged to ensure that there is no damage during transit. In case of exports, standard export packaging is done in wooden cases. All elbow fitings are marked with Grade, heat No. , Size, Degree and our trade mark. On special requests we can also make custom marking on our products.

Quality Assurance

In Taichang all fittings and flanges are subiect to strict inspection at each stage of the production process from starting material purchasing to product dispatch. They are visually examined for conformity to ASTM ASME MSS DIN EN and JIS codes and standards. Upon request, official certified inspection Agencies can be called in to witness the material reports dimensions and quality conformity of products.
