Lens expansion joints (KLO) are a type of axial single-layer expansion joints. These products are made of sheet metal, by mechanical molding. The design makes it possible to ensure the operation of the expansion joint in conditions of high pressure and temperature. In contrast TO the km and KMA compensators, KLO-work only for compression and stretching.
Lens expansion joints (KLO) can be manufactured and delivered to customers with various types of connecting fittings. Welding and flanged connections are standard. On request, this type of expansion joint can be completed with end parts according to the customer's drawing. KLO expansion joints are made of various steel grades: St. 3, St. 20, St. 09G2C, St. 12X18N10T, St. 10X17N13M2T, Incoloy 800, Incoloy 825, and others on request;
Diameter: from 100 mm to 4000 mm
Working pressure: from vacuum to 10 ATM*
Working environment temperature: -240 to 1200°C
The construction length is selected individually, taking into account the needs and wishes of the customer.
Most often, KLO expansion joints are used in heating systems where steam or water plays the role of the heat carrier, in power plants, chemical plants, as well as in the oil and gas industry.
This type of expansion joints are not unloaded from internal pressure, it is necessary to take into account the load when designing. They require the correct choice of locations in the pipeline system. They can be used for most compensation schemes.
* expansion joints for higher working pressure can also be developed on request.
