It is our goal to provide only the highest quality pipe to our clients. Therefore, we complete inspections during production, which includes every aspect from incoming raw material, through each step of the welding process and to product storage, and delivery. All inspections are geared toward ensuring we are in compliance with international standards. In addition, superior welding quality is assured by ERW and SAW welders who are certified for expert welding quality, and on-line and off-line UT inspections, hydrostatic tests and metallographic inspections are made in the ERW production line. What's more, the laser seam tracking system and the X-ray imaging NDT technique is also adopted to improve welding quality. Combined, these steps guarantee that our pipe products are high quality and satisfy our clients all over the world.
While maintaining the quality we are known for, we also seek to reduce our production costs, so we can continue to offer our products at the lowest prices. The use of automatic welding equipment also increases our production and lowers our labor cost greatly. An automatic flux drying machine and Lincoln welding machine also increase our efficiency. Relationships with local suppliers enable us to gain materials at reduced rates, which we can then pass on to our clients. Our location in Da Qiu Zhuang town provides us with easy access to labor, as well as major land, sea and air transportation methods.
