1. Background Information
This is our regular customer from Brazil, we have cooperated more than 5 years since 2018 and we has good relationship with each other . They are the largest manufacture of Heat exchanger and equipment manufacturer in Brazil , especially in oil&Gas and machinery sectors area, they also are partners of the Brazilian government.
The main part of the heat exchanger is U-tube, they purchased a large quantity U tube and other steel products from us every year. Our customer is very satisfied with quality, because we manufacture U pipe according to customer's drawings, including the radian of each steel pipe, without any mistakes.
