A lot. I have two friends who are engaged in welded pipe factory. The landlord said that there are many such factories in this place. The process and equipment for producing this kind of welded pipe are the same, except that there are more production lines in large factories and fewer production lines in small factories. Well-known welded pipe factories in Tangshan almost no longer produce this kind of polar pipes, so the factories that produce this kind of products are all small and medium-sized enterprises, and the quality is the same.
The price is slightly favorable for small enterprises. But if you want a large quantity, you have to find a medium-sized enterprise. If the landlord wants to buy this product in Tangshan area, I can give advice and help to the landlord. In view of the limited space, if the landlord wants to know more detailed information and materials about the industry, please leave qq or other contact information. I can discuss it further with the landlord.
