High temp. metallic element electric furnace with weld cooling - uses U brackets to support welded resistance metal tubes and air forced through U tube to provide cooling in weld regionThe oven has metallic high temp. resistance formed from hollow tube oriented vertically. The drawn tube is ...
Both ends of the branch pipe have a welded joint structure, and the weld bevel can be made according to standards or user requirements. It is suitable for preventing the backflow of medium in pipes of water, steam, oil, and superheated steam at high tempe...
The branch ll of the critical curve corresponds to upper critical solution temp-eratures as a function of pressure that are slightly raised with increasing pressure. The more the mutual miscibility of the two compo-nents decreases the more the branch ll of the critical curve is displaced to ...

2.The welding is argon arc weld(TIG) to avoid plate's oxidized 3.After welding the the inner tank ,we will make a full water pressure test to check the welding joint .After welding the jacket ,the full water pressure test be done for jacket too 4.After finishing the...
Weldable high-tensile steel excellent in low-temp. toughnessThis invention adds elements such as Cu, B, Cr, Ca, V, etc., to a low carbon-high Mn-Ni-Mo-trace Ti type steel, and allows the steel to have a tempered martensite/bainite mixed structure containing at least 60% of tempered ...
The sharp fall in hardness is apparent between ~3 mm to 8 mm from the weld center on both sides of the joint in Figure 5a, which is depicted as the thermo-mechanically affected zone (TMAZ). The drop in the hardness in the TMAZ is attributed to the lower peak temperature and cooling...
The high-temp. crack of the weld metal is prevented by the content of C in the wire, the SiO2 component in the flux and welding conditions, etc. The welding efficiency is thus improved.KATSUMOTO NORIONAKANISHI MUTSUO
