FAQ:
1.   Are you a trading company or factory?    We are a manufacturing factory.
2.   Do you have FDA certificate for the materials?   Yes, FDA is very important for the food processing machines.
3.   How do you control the quality?Â
     Quality control is very important to avoid material mixing and poor quality. We control the quality from beginning to the end. We only have 304 and 316L two different materials. 100% inspection on raw materials. During production, different materials in different places. After materials are finished, we choose 10% for inspection. If there is 0.1% problem in 10%, then no excuse to go ahead for inspecting 100% of the materials.
4.   About chemical components
      This is first concerning for customers. We take our materials to our laboratory for each lot. You may ask for the laboratory report any time.Â
5.  If there is any quality problem, how do you solve it?Â
We are very proud that we never let one customer leave us. We are not 100% perfect, there is some quality problem. We try our best to provide the correct materials in the beginning, so we need less time for quality problem.Â
If there is any quality problem, we take the responsibility. We believe what we are doing together,  it will get back tomorrow.  If we leave our responsibility, customers will leave us. If we always take our responsibility, we keep our customers with us.Â

7.   WarrantyÂ
     3 years warranty for all of our stainless steel products. Gaskets are not included due to the different application for customers.Â
8.    More questions are appreciated.Â
The Venturi Tube (Venturi tube) is divided into the built-in Venturi tube and the inserted Venturi tube according to the structure. Good results have been achieved in the measurement of combustion support, cold wind, gas measurement (blast furnace gas, coke oven gas, converter gas) and boiler primary air, two wind pipe diameter and low flow velocity in the hot blast stove of iron and steel plant. To solve the problems of accurate measurement of various types of gas flow at low pressure, large diameter and low flow rate in existing industrial enterprises. A fluid measuring device with wide measuring range and convenient installation. The unique structural design and data processing methods are based on strict fluid mechanics and are calibrated in the national key wind tunnel laboratory.
It can be widely used in the control and measurement of large diameter fluid in petroleum, chemical, metallurgical and power industries.
Characteristic
(1) the resistance to fluid is small, about 150Pa, so energy consumption is low.
(2) the pressure difference is big, the precision is high, and the measuring range is wide.
(3) good stability and smooth differential pressure.
(4) wide range of application. General gas, flue gas, and blast furnace gas with more impurities will not be blocked for long term use.
(5) easy to install and easy to maintain for a long time.
(6) the front and rear straight sections are shorter than the standard throttling devices, about 1D 1.5D before.
(7) online temperature and pressure self correction integrated structure.
