On 6th, August, one client from Vietnam inquired some carbon steel & stainless steel class 3000 forged fittings. Since there were special requirements on both end of the fittings, we emailed this clients for more details. An hour later, the client replied with concrete image and stated clearly about his demand. To discuss more conveniently, we moved to whatsapp and the client satisfied with the photos, which is perfectly complied with his requirement. One week later, the client added new items for quotation and placed order for all the items inquired.
Since the client reflected that the goods they bought before were not what they exactly want, we paid more attention on checking details. And we promised to show goods photos before shipment which is actually our common act to all of our customers.The following is the WhatsApp chat record between our company and customers, which gives positive feedback on our professional service.

Class 3000 Socket Weld Fittings
Class 3000 Socket weld fittings are widely used in piping systems. They feature an end with a socket-like opening, into which the pipe is inserted and then welded. 316L stainless steel socket weld fittings provide a secure and sealed connection. These fittings are typically used in applications where pipe sizes are relatively small and high-integrity connections are required, such as in chemical and petrochemical plants.
Types of Socket Weld Fittings
Socket Weld Cap
Socket Weld Elbow
Socket Weld Tee
Socket Weld Cross
Socket Weld Coupling
Socket Weld Union
Class 3000 Threaded Fittings
Class 3000 Threaded fittings have internal or external threads machined at their ends. They adhere to different thread standards, such as NPT and BSP. Threaded fittings are commonly used in medium-to-low-pressure applications and in systems that may require frequent modifications or maintenance.
Types of Threaded Fittings
Threaded Elbow
Threaded Tee
Threaded Cross
Threaded Coupling
