What is the tensile block?
It is most often found in drainage applications, the tensile block is a limit of concrete pipe. The block is used to prevent the pipeline separation separated under the force of carried fluids that pass through a bending or launch intersection. The dimensions of the tensile block should be calculated on the basis of the type of fluid transmitted, pipe diameter and existing ground conditions. The pressure should be taken into account that the liquid will be inside the pipeline. These forces may be enough to weaken the joints between the adjacent pipes. This effect can be exaggerated when the surrounding soil is weak or crumbly or where there is a table with high groundwater. By installing a large block of concrete on a bend or intersection, the draft energy of the liquid is partially absorbed and then redirected along the pipeline.
When considering the size of the desired tensile block Angle from bending is a key factor. As an example, in the case of towing iron pipes, the bending of 11.25 degrees will require a smaller tensile block than a bend of 45 degrees. This is due to the fact thatForces developed to reduce bending as the inner angle increases.
The use of concrete to create a tensile block is normally found only where the techniques of connecting the pipeline sockets were used. If the installed pipes have flange joints - where the pipe flanges are screwed together - the screws themselves will act as a draft limit. Similarly, a welded steel tube generally requires no further tension limitation depending on the thickness of the pipe material and the specified weld type.
An alternative form of restrictions in the use of pipes for socket SPIGOTA exists in the form of an anchor joint or anchor seal. Pipe joints traditionally use rubber seals between pipes to interfere and dirt leakage. The anchor seal is similar to the regular pipe seal, but has small steel teeth that lock the pipes to the position as soon as they connect to the adjacent tube. These steel teeth then budOU to act as a reduction of tension under pressure.
The term thrust block is also used in the ship building industry. In this application is a tensile block - alternatively known as a tensile box or a draft - a restriction system in the propeller mechanisms. This bearing can withstand the propeller shaft and transmits energy to the boat torso. By using this system, boat builders can optimize the power of the propeller to move the ship and minimize the lost energy through the movement of the propeller shaft.
