description

The welding neck flange is normally referred to as the "high hub" Flange. It is designed to transfer stresses to the pipe, thereby reducing high stress concentrations at the base of the Flange. The welding neck flange is the best designed butt-welded flange of those currently available because of its inherent structural value. Threaded (Screwed) Flanges:
The threaded flange is similar to the slip-on flange, but the bore is threaded. Its chief merit is that it can be assembled without welding, explaining its use in low pressure services at ordinary atmospheric temperatures and in highly explosive areas where welding create a hazard condition

Our welding neck flanges feature high strength, good toughness, and high resistance to corrosion, high pressure and temperature. The raw materials of them come into carbon steel, stainless steel, and alloy steel, low temperature steel and high performance steel. Also, we can provide customized flanges according to customers’ requirements.

Slip-on flange can be slid onto a pipe and then welded in place. It is made of carbon steel, alloy steel, and stainless steel. The industrial processes come into die forging, and machining. Our declaration: our company tries to enlarge market field not only in domestic but also overseas .what’s more, we have received a good reputation from our new and old customers who do business with us .we are sincerely to establish a long-term and friendly business relationship with you in the near future.

 

Blind flanges are made of carbon steel, stainless steel and alloy steel, etc. They are used to seal or block off a pipe, like a cover or cap. We can provide a wide range of blind flanges, in accordance to standards like ASME B*6.5, ASME B*6.*7, DIN ***4, DIN ***6, and so on. These flat face steel blind flanges are used to blank off pipelines, valves and pumps; it can also be used as an inspection cover. Blind flange is sometimes referred to as a blanking flange.
