Seeking help with issues regarding steel-aluminum transition joints
Thread Content
Dear marine friends, I’m seeking help regarding steel-to-aluminum transition fittings. 1. The steel-to-aluminum transition fittings I use come in sizes ranging from 3 inches to 32 inches, with a pressure rating of 300LB. These pipes are generally imported; what is their approximate price? ； 2. Currently, steel-aluminum transition joints must be imported, and the supply cycle is very long. Are there any other ways to shorten the delivery time for such equipment? Of course, using aluminum alloy flanges together with matching flanges is one such method. Thank you so much! !
Currently, the steel-aluminum joints imported are mainly from two brands: French T+C and Japanese Asahi Kasei. The steel-aluminum joints produced by French T+C use friction welding, while those made by Asahi Kasei employ explosion welding. French T+C’s steel-aluminum joints are recognized worldwide as having the best quality among bimetallic joints, and they are also the most expensive. The delivery time is usually at least two months. Due to their longer length, these joints require lower standards in terms of welding. The joint end face length of Asahi Kasei’s products in Japan is shorter, and their price is slightly lower than that of T+C’s products from France; however, it is necessary to control the current and the rate of temperature increase during welding, otherwise cracks may occur during the welding process. There are also many domestic manufacturers of steel-aluminum joints, but their quality is generally unstable. It is recommended to avoid using such domestic products for pipelines that carry hazardous materials or are in locations where maintenance and replacement are difficult; otherwise, any problems that arise will be costly to resolve. The most practical way to shorten the delivery time at present is to arrange for the import of products in advance by placing orders early. As for prices, they depend on factors such as the quantity purchased, nominal diameter, and design pressure; therefore, a separate quote is required each time. Foreign suppliers usually operate with zero inventory.
