Butt Welded Pipe Fittings

pipe fittings from Welflow

Pipe fitting is the general name of the parts and components in the pipeline system that plays the role of connection, control, direction change, diverting, and sealing.

Steel pipe fittings are all pressure fittings. The different processing technology is divided into four categories, namely butt welding pipe fittings (with welded and seamless pipe welded), socket welding and threaded pipe fittings, and flange pipe fittings.

Packing of Pipe Fittings

Pipe fittings of the small size are generally in one plastic bag.

Bigger size with Individual plastic bag packaging then put into cartons.

For some lower price items, Each carton with a big plastic bag, and the products are placed directly in the carton to solve the cost.

Color Marks & Color Boxes are also acceptable, and we have a success expensive about it.

Need Help In Choosing The Right Pipe Fittings?

Regarding Stainless Steel 304 material: In China’s local market, there is a different quality level of materials.

Such as stainless steel 304 standard is with at least 8 Nickel and 18 Cr. However, not all named 304 materials with standard chemical element composition. Few suppliers want to reduce the raw material cost; sometimes, they will choose maybe 7.5-7.8 Nickel or 8 Nickel with 17 Cr.

For all stainless steel products, no matter pipe fittings or ball valves, unit weight is the most important factor affecting prices. Clients who purchase from China for the first time will always be puzzled by this issue.- Why looks same products, has so many different prices. Not just 2 or 3 different prices, even each factory has a different price level.

This is because of unit weight, such as the wall thickness, length, etc.

Normally for small size (1/8″ to 3/4″), most the manufacture chooses tapping machines instead of CNC machine.

The difference between Tapping machined thread and CNC machined thread.

  • Tapping machine thread is production fast than CNC machine.- CNC machined thread pipe fittings cost will increase.
  • CNC machined thread precision will be much better than tapping machined thread.
  • For small size, CNC machine thread is more difficult than Tapping machine, and waste cutting head, increase total cost again.
