1.How many countries you already expeorted?
--We exported stainless steel pipes to more than 30 countries mainly from Egypt,Turkey,India,Eran,Dubai,Thailand,Philippine

2.What is our product range?
--Based on our stainless steel seamless pipe factory, We supply the ONE-STOP service fittings,flanges, valves etc.

3.What is your delivery time?
--It depends on the demanded quantities and your location, nearly in 15-50days.

4. Can you provide OEM service?
-- Yes. Welcom to contact us for more details discuss.

5. Can we visit your factory?
-- Warmly welcome. Once we have your schedule, we will arrange the professional sales team to follow up your case.

6.What is detail of the welded neck flanges you need know ?
--These pipe flanges attach by welding the pipe to the neck of the flange. This transfers stress from the flange to the pipe instead. It also reduces the stress concentration from the base of the hub. Weld neck flanges are often used for applications where high pressure is a factor. The inside diameter of the flange is designed to match the pipe's inside diameter. Weld Neck flanges with a hub have published specifications that range from 1/2″ thru 96″. 

Weld neck flanges are typically provided with a raised face, flat face, or RTJ facing. When a raised face is necessary for weld neck flanges, the standard height is 1/16″ for weld neck pipe flanges under 400#. For weld neck pipe flanges of 400# and up, the standard weld neck flange raised face height is 1/4″.

7.How to choose flanges?
--First,flanges are available in several materials, including carbon steel, stainless steel, and various alloys;
Second,it is essential to ensure it matches the pipe's outer diameter,don't forget pay attention to the size of flange. If the flange is too small, it may not be possible to attach it to the pipe.
Third,the pressure rating depends on the material and size of the flange,and maybe your working industry need specific flange pressure;
Forth,Flanges are available in several face types, need you to make decision(just as our part 2 mentioned);
End,several other application-specific factors should be considered when selecting flanges.
