Tyazhpromarmatura

History

On August 2, 1728 the Tula smith-armorer Maxim Perfilyevich Mosolov, the founder of an industrial dynasty of Mosolov, got the permission for construction of Myshegsky of "The water ironworks plant".

At the end of 1729 the Myshegsky plant gave the first melting. At the plant metal for sale was melted and the simplest products, mainly, ware and other household goods were produced.

In the XVIII century the Myshegsky plant delivered iron and cast iron to the Tula small-arms factory, cast guns for ground forces and navy of Russia.

Since the beginning of the 19th century the plant began to make art casting.

In the period of Patriotic war of 1812, the Crimean war of 1853-1856 at the plant orders of the Ministry of Defence on production of different caliber of cores, grenades, a case-shot and bombs were executed.

At the end of the 19th century expansion and reconstruction of the plant is carried out. The Myshegsky plant became on the level of modern metallurgical production.

In the years of World War I the plant started the production shells, mines, grenades.

After the October revolution of 1917 and the period of civil war the Myshegsky plant was the only operating truboliteyny plant of the center of Russia. Released pig-iron pipes for water supply systems, hydraulic columns, axle boxes, brake shoes, bearings and other casting for railway transport.

In the second half of 1921 and in the first half of 1922 the plant worked only to order with Kashira GRES – the firstborn of the Soviet electrification, releasing special pig-iron pipes and connecting parts to them.

In 1925 the pre-revolutionary production rate was for the first time exceeded. By the end of the recovery period the plant satisfied 25% of need of the country for water pipes, taking the third place among the manufacturing plants of this type of products, and provided 50% of the general production in the country of connecting parts to pipes.

Since the end of 1938 – the Myshegsky reinforcing plant. The release of a pipeline armature is mastered: latches with a diameter from 100 to 1600 mm, pressure from 2.5 to 100 atmospheres, check valves on pipelines with a diameter from 200 to 2200 mm, hose locks.

In the early fifties of the XX century for a short period the plant developed production of conical cranes on gas pipelines with a diameter from 50 to 700 mm on pressure 64 atmospheres.

In the 60th years of the XX century – production of ball valves with a diameter up to 700 mm is developed; shutoff and safety valves for the NPP.

Since February, 1972 – the Aleksinsky plant "Tyazhpromarmatura".

On a threshold of the 90th years the Tyazhpromarmatura plant completely developed production of ball valves for transportation of gas with a diameter from 50 to 1400 mm which conform to requirements of international standards.

In November, 1992 the plant is privatized and became public joint stock company – JSC Tyazhpromarmatura.

In 1997 the plant one of the first Russian enterprises certified a quality management system according to the international standard ISO 9001 and obtained the license of American Petroleum Institute according to the API Spec 6D standard.

In November, 1997 the prototype of a gate latch for oil pipelines on diameter of 350 mm is made.

In 2006 the plant developed and "Eastern Siberia-Pacific Ocean" of DN to 1200 mm and PN up to 15 MPas, with seismic stability to 10 points on a scale of MSK developed production of unique gate latches for the oil pipeline. In October, 2006 for implementation of this project of JSC Tyazhpromarmatura Reinforcing Oscar behind number 1 is handed.

In 2008 production of a hi-tech pipeline armature for the NPP is resumed. By the beginning of September the first production lot of a special armature for nuclear power – nine wedge latches on DN of 150 mm of Pp of 11 MPas for the New Voronezh NPP was produced.

In 2008 at the enterprise started development and mastering of a complete line of the return locks for automatic overlapping of the pipelines with a diameter of pass from 300 to 1200 mm expected work in the range of pressure from 2.5 to 12.5 MPas.

In 2010 the plant is renamed into "Aleksinsky Plant of a Heavy Industrial Armature" Private company
