High Performance Expansion Bellows

Be familiar with the design drawings and data, make clear head and branch pipe arrangement, direction, and process and construction installation requirements.

Familiar with the situation, understand the design along the line of the existing distribution of plane and elevation control points.

According to the pipeline plane control points and existing, and connecting with the actual terrain, do a good job in the measured data, the measured rough sketches.

Approach to the construction unit after the handover of leveling points and traverse points for retest, after closure comply with the design requirements, traverse points, leveling points of encryption, each 60 meters a worldwide level points, encryption point must be closed adjustment, leveling point L closure of 20), ensure the accuracy of the encryption points, in order to meet the drain height, the precision of the linear control.
