Coal powder pipe with three - way expansion joint

The novel three-way corrugation compensator for coal cinder pipe is suitable for piping system with thermal displacement requirements of other solid dust and particle gas-solid two-phase fluid with pressure less than 0.25MPa.

BYZMF type coal-dust pipe new type triple corrugated expansion joint:

1, attract any direction displacement at the same time, should meet the following formulas: X XO, or less, and Y Ym or less type X and Y is the actual axial and lateral offsets, Y can be any lateral displacement vector and.

2. 1 in the product code shall be filled in according to the required length. If WZMF500 * 8-j-2200, the delivery length of the product shall be 2200 mm.

3. If the actual size of the pipe does not match the size of the pipe section in the table, it shall be noted separately when ordering.

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

Because of the power plant boiler pulverized coal pipe using the packing type compensator to produce coal powder leakage, and packing quality, and the displacement of the old constraints under temperature, make the pipe system expansion, affect the normal operation of the pipeline system.According to these five weak link and pulverized coal pipe concrete to working conditions, comprehensive pulverized coal pipe, according to the standards of the expansion joint manufacturers association EJMA, we design the secondary seal, annular spherical more turn the pulverized coal pipe new three to the bellows expansion joint, realizes the short installation is apart from the new requirements of large compensation.

Design pressure: PN is less than or equal to 0.5MPa

Design temperature: T = 450 ℃

BYZMF type coal-dust pipe new type triple corrugated expansion joint applicable scope:

Suitable for pulverized coal + hot atmosphere of liquid and solid, = velocity of 15 ~ 30 m/S, working temperature 60 ~ 450 ℃, wind pressure or less 500 mmh2o of primary air and secondary air, three times the wind pipe any direction motion compensation.

Suitable for pipe system with other solid dust and particles of gas - solid two-phase fluid with pressure less than 0.25MPa.
