Estimated maximum stock
Container capacity, meter, process flow chart according to PIC001 specification of Process Industry Practice Association Standard ( PIP ) , equipment notes should indicate tower capacity. Regularly inspect the tank area and record the storage capacity. Recording is carried out using a tank inventory, and tank capacity information should also be recorded in these tables.
2. Method for obtaining process technology information
( 1 ) Basic process technology information can be obtained from the project process package provider or the project project general contractor;
( 2 ) Obtain detailed process system information from the design unit, including detailed drawings, documents and calculation books for each major.

Woven Fence are weaved by galanized Wire , PVC wire or Stainless steel wire.
1. Chain Link Fence is extensively used as fences for playground and gardens, super highway, railway, airport, port, residence, etc. Also can be used for breeding of animals.
Chain link fence can be with barb wire, Razor Wire on top for high security.
2. Field Fence also called Grassland garden mesh(Hinge Joint Fence) usually made from hot dip galvanized wire with zinc coating of 230g/m2.
Top and bottom wire: 2.5mm
inner wire: 2.0mm
3. Gabion Basket made of hexagonal Galvanized/PVC/Zinc-Al double twised mild steel wire mesh.
Gabion baskets can be supplied in various lengths, widths and heights. In order to strengthen the baskets, all the edges of the structure shall be selvedged thicker wire diameter.
4. Bullet-proof mesh is the most popular as window screen. It made of stainless steel wire and powder coating.
The Bullet-proof mesh transparent without any sense of vertigo, it is like a layer of transparent colored glass when looked from inside to the outside of the rom and hazy and blurred from outside to the inside of the room.
