DMH United Steel's Ceramic Lined Bends and avoids product attrition.It reduces considerabley degradation of conveyed material and avoids formation of angel hair through its patented deflection chamber.

Ceramic Lined Bends for Pneumatic Conveying

Tubes and bends in pneumatic conveying lines are suffering more or less abrasion. DMH United Steel's ceramic lined pipes resists abrasion and avoids product attrition.It reduces considerabley degradation of conveyed material and avoids formation of angel hair through its patented deflection chamber.The compact design reduces cost of pipe support and installation. It is automatically self-purging with little pressure drop. 

The offered bends are manufactured and coated by top class ceramic with the aid of pioneering techniques at our hi-tech production. These ceramic lined bends are commonly used in industrial pipeline fitting for changing the pipe direction. Moreover, we are providing these Ceramic Lined Bends at industry leading prices.

Features:

• Highly durability
• Leakage proof design
• Ruggedness
• Corrosion resistance

Wide application and concrete case of the Ceramic Lined Bends

Concrete case

Application of metallurgy, electric power industry

The electric power industry, metallurgy, mud, ash conveying of pulverized coal, lime gypsum slurry and consumes an amount of metal pipeline. The use of ceramic composite pipe to replace other pipelines, with high wear resistance, long life, easy installation, significant economic benefits.

Application of mine and coal industry

(1) mines: mine filling, concentrate and tailings delivery pipe wear serious, formerly in the slag conveying pipeline such as Panzhihua, Daye Mine the useful life of less than a year, the line can make life can be improved by more than 5 times.

(2) coal: Coal Preparation and long distance pipeline commonly used wet conveying, conveying pipe both wear resistance and corrosion resistance, using the tube can be as long conveying pipe, economic benefits is considerable.

An elbow is a pipe fitting installed between two lengths of pipe or tubing to allow a change of direction, usually a 180° or 90° angle, though 45° elbows are also made. The ends may be machined for butt welding (SW) or socketed welding(SW) etc.

Most elbows are available in short radius or long radius variants. When the two ends differ in size, the fitting is called a reducing elbow or reducer elbow.

Elbows are categorized based on various design features as below:

• Long Radius (LR) Elbow is also called LR elbow – means the radius is 1.5 times the pipe diameter
  • L/R 45°Elbow: Long radius 45 degree elbow changes the direction by 45 degrees.
  • L/R 90°Elbow: Long radius 90 degree elbow changes the direction by 90 degrees.
  • L/R 180°Elbow: Long Radius 180 degree return bend allows complete reversal of flow.
• Short Radius (SR) Elbow is also called SR elbow, – means the radius is 1.0 times the pipe diameter
  • Short radiu 45°Elbow: Short radius 45° elbow changes the direction by 45 degrees.
  • Short radius 90°Elbow: Short Radius 90° elbow is same as LR90 except for the measurement between end of elbow to center line is 1 x NPS.
  • Short radius 180° Elbow: Short Radius 180° return bend allows complete reversal of flow

Size range:

• Seamless elbow: 1/2"-24" DN15-DN600
  
• Welding elbow: 6"-72" DN150-DN1800
• Wall thickness: Sch5-Sch160 XXS
• 国标、美标弯头尺寸
• 美标弯头壁厚重量
• External arc length of elbow

Recommended type of pipe elbows:

• Big diameter elbows
  
• Larg diameter elbow
  
• Small size elbow
  
• Forged Elbow, Elbow Fittings
