Product Description

 

vulcanized fibre tube is the first cotton paper to provide zinc chloride solution tank, rolled on the core to achieve the predetermined thickness of the pipe wall, and then through desalting, drying, pressure pipe, coarse grinding, fine grinding and other processes to achieve the ideal inner and outer diameter products.

The density of steel paper pipe is 1.4 g/cm3, which has good physical, mechanical properties, electrical insulation, arc resistance and arc extinguishing properties. Because of its good processability, steel paper tubes can be finely ground and polished. Rob, spin, thread, cutting to achieve the shape and size.

Q1:Are you a trading company or manufacturer?
We are a manufacturer, We have our own workshop producing electrical insulation polyimide film.
Q2: Can you send samples for testing?
A4 size Samples & Small rolls are free supplied, customers just need to pay a litter shipping charge.
Q3: How can you guarantee the quality of mass goods is the same as the sample sent to me before?
We kept another same sample and marked it on the company when we sent it to the customer. So our products will be based on and also we will test the product before shipment.
Q4: Which package do you use?
The package is an important part to avoid goods breaking in transportation. We will choose suitable packing depending on the materials.
