Without further ado, here we go:

1. What Is Pipe Fittings?

Pipe fittings are the general term for parts and components that play a role in connection, control, change direction, diversion, sealing, and support in the pipeline system.

Steel pipe fittings are all pressure pipe fittings. According to different processing technologies, it is divided into four categories, namely butt welding pipe fittings (two kinds of welding seam and no welding seam), socket welding and threaded pipe fittings, and flange pipe fittings.

2. What Are Threaded Pipe Fittings?

Threaded pipe fittings are pipe fittings with threads. Commonly used in water gas pipes, small diameter water pipes, compressed air pipes, and low-pressure steam pipes. Connect with a threaded pipe end to form a pipeline. Appropriate glue (such as thick white paint, lead monoxide glycerin glue, etc.) can be coated on the threads to ensure sealing.

4. Where To Buy Pipe Fittings?

SANVO is one of the professional pipe fittings suppliers, manufacturers, distributors, wholesalers, and exporters in China, and supplies custom/industrial/household/forged/casting pipe fittings.

1) Custom Pipe Fittings

Customized pipe fittings are pipe fittings that can be produced according to drawings or samples, or customer-specific needs.

2) Industrial Pipe Fittings

Pipe fittings made of carbon steel are used in pipe systems that carry liquids or gases, such as oil, water, natural gas, or steam. Apart from that, carbon steel fittings are highly demanded in construction and maintenance activities in residential construction, commercial construction, electric power generation, petroleum refining, shipbuilding, and other industrial-use sectors.

3) Household Pipe Fittings

Stainless steel is widely used for making pipe fittings because of the fact that it is highly resistant to oxidation and corrosion in various natural and man-made environments. Stainless steel is actually a ferrous alloy containing a minimum of 10% chromium. The selection of the right grade of stainless steel for a particular application is really important. A range of pipe fittings, gs as pipe tees, hose nipples, and pipe elbows, is made of stainless steel. Stainless steel fittings are usually used for household pipelines.

4) Forged Pipe Fittings

Forged pipe fittings include carbon steel nipples, carbon steel couplings, stainless steel nipples, stainless steel couplings, and are utilized to connect nominal bore schedule pipes and pipelines.

5) Casting Pipe Fittings

Casting pipe fittings to include stainless steel threaded pipe fittings, such as stainless steel elbows, stainless steel tees, stainless steel hose nipples, stainless steel hex bushings, stainless steel reducer couplings. And the casting pipe fittings are used for domestic pipe systems, such as water supply pipes.
