Lens compensators quenched temperature changes the length of rectangular and circular gas air (PGVU), as well as pipelines for steam / water thermal power plants, etc… Enterprises. Lens compensators are operated in contact with non-aggressive or maloagressivnymi environments.
Lens compensators, depending on the operating characteristics, and actions of climatic temperatures, made from steel grades: St20, St3sp5, 09G2S, 08X18H10T, 12X18H10T, 10X17H13M2T, 08H18N9, 12X18H10T, 20H20N14S2, 10H17N13 M2T, 09G2S, Steel, 20, 10, 3, 18K, 17GS.
Compensators of this type are made according to OST for axial lens compensators section 10 — 2200 mm, and quenched with temperature axial extension of pipelines, which are operated in maloagressivnyh and non-aggressive environments with temperatures up to 300 ° C, nominal working pressure up to 16 kgf / cm 2 (, 6MPa) .
Lens compensators is further equipped with 1) a protective inner casing (liner or glass) to protect the corrugations or lenses from mechanical impurities, which come through the compensator with the working environment; 2) drainage pipes intended to drain the condensate that forms in the ground cavities lenses, 3) ties (clamping devices).
— Conditional pressure range, depending on the vacuum not more 10,0 MPa.
— Nominal size range of 50 — 8000 mm
— Temperature range from -240 ° C to +1000 ° C.
Lens compensators are manufactured in two versions: welded and flanged.
Compensators lens axis
Produced according to OST: single-lens compensators — OST 34−10−569−93, 2-lens — OST 34−10−570−93, 3-lens compensators — OST 34−10−571−93, 4 lenticular — OST 34- 10−572−93.
Angle Lens compensators
1. Angle Lens.
Compensators angle lens made according to OST 1-lens compensators — OST 34−10−573−93, 2-lens — OST 34−10−574−93, 3-linzovye- OST 34−10−575−93, 4-lens compensators — OST 34−10−576−93.
2.Linzovye dual angle.
Dual Lens Angle (2-planar) are made according to OST: single lens — OST 34−10−577−93, 2-lens compensators — OST 34−10−578−93, 3-lens — OST 34−10−579−93, 4-lens compensators — OST 34−10−580−93.
Lens compensators of round section
Compensators lens made of single-layer half lenses and lens welded in the troughs and peaks of the wave. With high rigidity for angular and shift movements, such expansion joints are widely used to compensate for axial displacement in those systems that have a large working pressure or temperature. They are commonly used in chemical, gas, oil refining industries to compensate for temperature fluctuations turbine towers and heat exchange equipment.
Compensators lens PGVU square / round
Quench the thermal elongation (PGVU) gas air heating plants. Such joints are used in maloagressivnoy medium at t ° from -20 ° to + 425 ° C and pressurized to 1500 mm water. Art. (0.015MPa).
Compensators lens PGVU round have diameter of 150 to 6000 mm. They are issued one-, two-, three- and four-lens and have different compensating ability. Compensators Rectangular lens PGVU have dimensions of 300 x 400 — 7850 x 8000 mm, and there are also single, 2, 3 and 4 lens with a different compensating ability. Compensators lens axis circular are made according to OST 34−10−569−93. They dampen temperature fluctuations pipe lengths, working in conditions maloagressivnoy medium, when heated to 300 ° C and pressures up to arbitrary 1,6MPa (16kgs / cm 2) and t ° to 425 ° C for ≤ DN 400 mm. Non-metallic expansion joints of special materials can be used in highly aggressive environments and at temperatures used to proc eed.
