PIPELINE ANCHOR FLANGES Anchor flanges are used to restrain pipeline movement caused by thermal expansion changes or external forces. The most common method of securing an anchor flange is to embed it into a concrete thrust block, thereby spreading the pipeline forces throughout a large foundation. However, anchor flanges can be secured in other ways as necessary to overcome the axial force in the pipeline. WeldFit designs anchor flanges to satisfy ASME codes, customer requirements and best...
A coupling is a mechanical part that is used to couple two shafts (active shaft and driven shaft) in different mechanisms to rotate together to transmit torque. It is understood that in the high-speed heavy-duty power transmission, some couplings also have the function of buffering, damping and improving the dynamic performance of the shafting. The coupling consists of two halves, which are respectively coupled to the drive shaft and the driven shaft. 1. Positioning screw fixing: The two...
Tees straight and reducing The primary purpose of a Tee is to make a 90° branch from the main run of pipe. Standard there are 2 possibilities, on behalf of the equal tee and reducing tee. The equal tee (or straight tee) is used as the branch has the same diameter as the run-pipe. The reducing tee is used as the branch has a smaller diameter as the run-pipe. Dimensions and Standards When we talk about a tee NPS 3, a equal or straight tee is intended. With a tee NPS 3 x 2 a reducing tee is...
1. Before the pipe and pipe fittings are bonded, apply a dry cloth to wipe the socket side and the outside of the socket. When the surface is sticky with oil, wipe it with acetone. 2. The pipe section should be flat and vertical pipe axis and chamfered; before the bonding, the inserted marking line should be drawn and the test insertion should be carried out. The test insertion depth can only be inserted into the original depth of 1/3~1/2. When the gap is too large, the bonding method is...
