Tubular KT-joints are quite common in offshore structural design and despite the crucial role of stress concentration factors (SCFs) in evaluating the fatigue performance of tubular joints. However, the SCF distribution in internally ring-stiffened KT-joints have not been investigated and no design equation is currently available to determine the SCFs for this type of joint. In the present pape...

Thrust chamber cooling system is an important issue in liquid missile systems. In this paper, two more applicable systems, that is, regenerative and radiation cooling systems are studied. Regenerative cooling systems, which are mostly used in high pressure thrust chambers, are normally in two forms, tubular wall structure and double wall structure. Tubular structure has mostly a square form str...

Intumescent coating is able to provide effective fire protection with both practicality and aesthetics. In this study, expansion performance thermal physical property experiments are firstly carried out obtain the basic parameters at different temperatures. Then, response model of concrete-filled steel tubular (CFST) structure under intumescent in a established. Finally, based on experimental d...

An electrocatalytic membrane reactor assembled using a nano-MnO2 loading microporous Ti membrane as an anode and a tubular stainless steel as a cathode was used to oxidize n-propanol to produce propionic acid. The high efficiency and selectivity obtained is related to the synergistic effect between the reaction and separation in the reactor.
