Forge & Fittingsdistributors both domestic and foreign forged fittings and forged pipe fittings to complete your forge, flange and bar order.
Our forged fittings can come in Elbows, Street Elbows, Tees, Crosses, Couplings, Reducers, Outlets, Inserts, Caps, Unions, Bushings, and Plugs.
A cross fitting allows four direction transition in pipeline fields.
Forged steel fittings are very high quality and are meant to have higher yields to high pressures.
On forged steel fittings, it is important to have uniformity of the walls of the fitting, as well as crisp threading to prevent stoppage in flow through the system.

Forged steel is an alloy of carbon and iron.
Manufactured by a series of compression under an extremely high pressure, steel forgings normally have less surface porosity, finer grain structure, higher tensile strength, better fatigue life/strength, and greater ductility than any other steel processing.
Forging is one of metal pressure processing methods, referring to that use pressure to change the shape of metals so that can acquire forging pieces having mechanical property, shapes and dimensions.
The followings are the classifications of forging.
1. Hammer smith forging
The pattern of hammer forging is the same as blacksmithing. The work pieces are heated to the forging temperature, then, put between hammer flattener and drill plate for further forging. Small pieces can be made by hand, called as blacksmithing. Larger pieces need steam hammer. The work pieces are put between drill plate and hammer flattener. Structure of steam hammer is determined by forging capacity. Light one is single stand while heavy one is double stands.
2. Drop hammer forging
The difference between drop hammer forging and flat forging is that there is a mold cavity on hammer used for drop hammer forging. Work pieces suffer from two aspects of pressure or impact force in mold cavity, plastic deforming according to the shape of mold cavity. To ensure sufficient flowing of metal, forging is usually divided into several levels. Transformation in every level is gradual, advantageous for controlling flowing direction. Quantity of level depends on shape and dimension of forging pieces, forgeability of metal and precision of work piece.
3. Press forging
Press forging is a forging method that metal is extruded and formed inside mold under the pressure at a low speed. Due to metal stressed for a long time, extrusion is not only carried out on the surface of forging piece, but also carried out in center. Therefore, for even inside and outside, the quality of products is also better than that of drop hammer forging.
Forging used for manufacturing the shell of cellphone can reduce time of CNC effectively, having low relative cost. Moreover, aluminum alloy whose aluminum content exceeds 95% can be chosen for anodic oxidation.
Manufacturing process:
Upset forging means that forge one of ends of an even long rod. Clamp the rod in the mold; heat one of end to high temperature. Force the end along the axial direction, upsetting and forming.
5. Roll forging
Use two round rollers (25%~75% reduction of diameter; the other part can be cut into groove shape based on requirements). Put rod into the two rollers and tight it, then, continue rotating, roll compacting the rod, reducing diameter and pushing it forward; when the rollers rotate to opening position again, withdraw the rod back to original position for the next cycle rolling, or send the rod to another grove for other construction.
Forged steel is often used in weapons, thanks to its strength and durability.
Forging steel is a metal-working process which involves the use of hammering or pressing techniques to alter the steel’s shape, followed by heat treatment. This method produces in the steel a number of properties which distinguish it from other treatments of this metal, for example casting, where liquid metal is poured into a mold and then left to solidify.
圣rong and Durable
圣eel forgings have a generally higher strength and are typically tougher than steel processed in other fashions. The steel is less likely to shatter on contact with other objects for example, making forged steel highly suitable for items such as swords. This increased strength and durability is a result of the way in which the steel is forced into shape — by pressing or by hammering — during the forging process. The steel’s grain is stretched by this process, and ends up aligned in one direction, as opposed to being random. Following the pressing or hammering, the forging is cooled in water or oil. By the end of the process, the steel is stronger than it would have been had it been cast, for example.
Anisotropic
A steel forging’s strength isn’t consistent all the way through; instead, steel forgings are anisotropic, which means when the metal is worked on and deformation occurs, the steel’s strength is greatest in the direction of the resulting grain flow. This results in steel forgings which are strongest along their longitudinal axis, while in other directions, the forging will be weaker. This differs from steel castings, which are isotropic and therefore have almost identical properties in all directions.
Consistency Between Forgings
Since the process of forging is controlled and deliberate, with each forging undergoing the same steps, it’s typically possible to ensure a consistent material over the course of many different forgings. This is in contrast to cast steel, which is more random in nature due to the processes used.
