High Pressure Carbon Steel pipe fittings forged A105 elbow
MORE OF US
Forged elbow is a pipe which changes the direction of pipeline. Because it is forged, it can bear higher pressure and can bear up to 9000LB. So it is also called high pressure elbow. It mainly includes socket welded elbow and threaded elbow, in which the forged elbow is 45 degree forged elbow and 90 degree forged elbow. The pressure level of forged socket welded elbow is divided into: 3000LB, 6000LB, 9000LB, the pipe wall thickness grade of socket welded elbow 3000LB is Sch80, XS; the pipe wall thickness grade of 6000LB is Sch60; the pipe wall thickness grade of 9000LB is XXS; and the forged thread elbow is XXS. The pressure level is divided into 2000LB, 3000LB and 6000LB. The wall thickness grade of 2000LB pipe fitted with threaded elbow is Sch80 and XS; the wall thickness grade of 3000LB pipe fitted with Sch60; and the wall thickness grade of 6000LB pipe fitted with XXS.
Elbow is one of the commom pipe fittings applied in oil&gas industry. An elbow provides a change in material-flow direction. This adds pressure losses to the system due to impact, friction and re-acceleration.As product enters the inlet of the elbow, it typically continues moving straight ahead to the first (or primary) impact zone. The product is then deflected at an angle toward the outlet of the elbow. The deflection angle is determined by the elbow design, the product’s characteristics, the conveying velocity, and specific load (also called the product-to-gas ratio). In many designs, the product will hit one or more secondary impact zones before exiting the elbow.
Impact forces can cause severe degradation of fragile or breakage-sensitive products, generating a large amount of fines or dust and creating quality issues. Heat-sensitive products, such as plastic pellets, can overheat on the contact surface this can result in unwanted tails or streamers on the pellet or film build-up on the surface of the elbow, which can eventually lead to product contamination. Abrasive products can cause wear, leading to work-out elbows and system leaks and causing maintenance and safety issues
Elbows can be divided into different degrees,45 degree and 90 degree.There are also different kinds of elbows sold in the market, like tube elbow, pipe elbow, reducing elbow, forged elbow, welded elbow, threded elbow, ect. Today we would like to talk about elbows made by drop forging. Forged 90° elbows are manufactured as SR (Short Radius) elbows and LR (Long Radius) elbows.
Forged SR (Short Radius) Elbows
These forged elbows have a Center-to-Face dimension of 1.0 X diameter. They are typically used in tight areas where clearance is the main issue.
Forged LR (Long Radius) Elbows
These forged elbows have a Center-to-Face dimension of 1.5 X diameter. They are the most common type of forged elbow and used when space is available and flow is more critical.
