Dear Customer,

 

We have a professional worker team to produce any kinds of middle and superior quality thermal insulation pipe sand pipe fittings.

Please feel free to contact us any time if you have any question.

We will provide you the most intimate and professional service

 

 

 

         

1: Are you a manufacturer or a trading company?

We are a manufacturer which has  more than   2 0 years' history.

2: Where is your manufacturer? How to visit it?

Our factory located in  Yutian Economic Development Zone ,TangShan , China. A bout 1.5 hours drive time to  Beijing and TianJin airport . Mainly producing pre-insulated pipes, HDPE outer protection pipe and 3PE anti-corrosive pipe.

You can take a plane to Beijing or Tianjin .then we could pick up you at the airport .

3: How do we control our products' quality?

We have professional quality control workers and quality inspection center(CNAS lab)  to control the entire production quality.     

4: How do you transport these products?

We use straps to hoist pre-insulated pipes, it can avoid no damage to our products, no hooks for lifting pipe directly. During the handling process, collision, tossing and more ground drag scrolling are strictly forbidden.

In the process of long distance transport, the pipes should be fixed, and not damage outer protecting pipes and insulating layers.

5: Can I customize some other sizes of products?

Yes! We can according to the customer's request.
If you have any other questions, please don't hesitate, contact us.
