Kunshan ventilation pipe in the application of the scope of life is  very broad, in the years of development of the company, the company has  accumulated a set of construction experience, today Kunshan ventilation  pipe to come and share some of Suzhou ventilation pipeline before the  preparatory work.
1, carefully look at the entire ventilation and air conditioning engineering design drawings. Before the start of the design drawings must be reviewed whether the  provisions of the construction regulations and technical standards, and  view the layout of the ventilation pipe for Kunshan and set the needle  to assess whether there are irregularities, excessive situation.
2, study the design drawings of the ventilation pipe requirements. To understand the structure of the whole building on the electrical,  the building within the pipeline direction, coordinates and other  elements of the layout and Suzhou ventilation pipe between the cross or  cross the problem has a detailed understanding and marked in the design.
3,  the relevant technical staff and construction workers to reach  agreement, design drawings marked Kunshan ventilation pipe size, size,  interface to meet the design standards of construction workers in strict  accordance with the design drawings. At the same time clear the construction of technical standards and the  use of equipment, to establish a link Suzhou ventilation pipe  connection method.
4, according to the design drawings, construction workers to draw  their own layout and layout of the construction program sent to the  construction unit to verify.
5, all documents in place, including the construction contract,  standard certificate, technical support certificate, construction  authorization and other legal documents related to the law.
6, check the equipment and equipment is reasonable.
