Widely used in 100~600MW generating units, fundamentally solve the problem of coal powder leakage, ensure the normal operation of the unit.

Product feature：

1. When attracting displacement in any direction at the same time, the following formula should be satisfied:

X≤XO, and, Y≤Ym, X and Y are the actual axial and transverse compensation quantities, and Y can be the vector sum of any lateral displacement.

2, the product code 1 should be filled in according to the required length, such as WZMF500×8-J-2200, then the delivery length of the product is 2200 mm.

3. If the actual size of the pipe is inconsistent with the size of the nozzle section in the table, it should be indicated separately when ordering.

Design basis of BYZMF new three-way corrugated expansion joint for pulverized coal pipelines:

Due to the pulverized coal leakage caused by the use of packing compensator in the pulverized coal pipeline of boiler in power plant and the constraint displacement of packing quality under temperature, the expansion of the pipeline system is not smooth and the normal operation of the pipeline system is affected. Let the product go all over the world, Zhongyuan valve fittings reminds Luanda friends that this information is valuable: In view of these five weak links and the working conditions of pulverized coal pipeline and the specific requirements of integrated pulverized coal pipeline, according to the American Expansion Joint Manufacturers Association standard "EJMA", we innovatively designed a new three-way corrugated expansion joint of pulverized coal pipeline with a secondary seal and a spherical shape with relatively supporting rotation, realizing the new requirements of short installation distance and large compensation.

Design pressure: PN≤0.5MPa

Design temperature: T = 450℃

The application of BYZMF type pulverized coal pipeline with new three-way corrugated expansion joint：

Suitable for pulverized coal + hot air solid = phase fluid, flow rate of 15~30m/S, working temperature of 60~450℃, wind pressure ≤500mmH2O primary air, secondary air, three air pipeline moving compensation in any direction.

Suitable for pressure ≤0.25MPa with other solid dust, particles of gas-solid two-phase fluid thermal displacement requirements of the pipeline system. ZhongYuan absorb values, integrity and customer loyalty, ZhongYuan's customer service personnel reminds us of the key points of product knowledge in the field of space flight application: The product is resistant to high temperature, no leakage, no accumulation of powder, small displacement stiffness; Can absorb any direction displacement, good flexibility to ensure the boiler and pipe expansion freely; Easy installation and maintenance, simple hanger, long service life, comprehensive investment. Widely used in 100~600MW generating units, fundamentally solve the problem of coal powder leakage, ensure the normal operation of the unit.
