A spojnica is a device used to connect two shafts together at their ends for the purpose of transmitting power. Спојнице обично не дозвољавају искључивање вратила у току рада, however there are torque limiting couplings which can slip or disconnect when some torque limit is exceeded.

The primary purpose of couplings is to join two pieces of rotating equipment while permitting some degree of misalignment or end movement or both. By careful selection, installation and maintenance of couplings, substantial savings can be made in reduced maintenance costs and downtime.

The primary function of API is to define and prepare standards to qualify the oil and fuel industry, making sure the security and reliability of the commercial devices. Iz tog razloga, the devices with API spec is not only thought about as extremely certified but leading placed in the field as well.

Classification of API

API is divided into 3 groups: tubing in grades H40, J55, and N80; restricted-yield tubing grades L80, C90, and T95; high-strength tubing in smooth grade P110. The number in the grade designation represents the most affordable yield strength of the steel in thousand psi. API defines the yield strength as the tensile stress required to produce a particular total elongation per unit length on a standard test specimen.
