ODM OEM Forged Steel Fittings Manufacturers Suppliers – 90 Reducing Elbow – DIKAI

Product introduction

We(CNG) supply style 90RT 90° Reducing Elbow with Threaded Small End(Add-a-cap). They are used for connecting Standpipe to control, distribute, or support pipeline in different sizes or directions. By groove connection, project time is saved a lot with fast installation and easy maintenance. We supply grooved pipe fittings for fire fighting system.The Elbow are made of ductile iron per ASTM A536 Gr. 65-45-12 and or ASTM A395 Gr. 65-45-15. C-E dimensions are manufacturer’s standard.It is connected with coupling and cooperates with each other. It is used in the place where the diameter of fire pipeline changes.  which is mainly used in water spray system and fire water system. Grooved pipe parts together with grooved couplings ensure fast and easy installation of piping. Grooved parts

replace Grooved pipe parts together with grooved couplings ensure fast and easy installation of piping. Grooved parts replace the traditional welded pipe parts.

the traditional welded pipeIt is listed by Underwriters Laboratories of the FM Approved.We are looking forward to establish long term business relation with you.

In the pipeline system, the elbow is a pipe fitting that changes the direction of the pipeline. According to the angle, there are three commonly used elbows of 45° and 90°180°, and other abnormal angle elbows such as 60° are also included according to engineering needs. Let’s follow the 90° Elbow editor to take a look at the process of thermoforming!
The hot push elbow forming process is to use a special elbow push machine, core mold and heating device, so that the blank sleeved on the mold moves forward under the push of the push machine, and is heated, expanded and bent during the movement. the process of. The deformation characteristic of the hot push elbow is to determine the diameter of the tube blank according to the law of constant volume before and after the plastic deformation of the metal material. The diameter of the tube blank used is smaller than the diameter of the elbow, and the deformation process of the blank is controlled by the core mold to compress the inner arc. The metal flow is compensated to other parts that are thinned due to diameter expansion, thereby obtaining an elbow with uniform wall thickness.
The hot push elbow forming process has the characteristics of beautiful appearance, uniform wall thickness and continuous operation, and is suitable for mass production. Therefore, it has become the main forming method for carbon steel and alloy steel elbows, and is also applied to certain specifications of stainless steel elbows. Is forming.
The heating methods of the forming process include medium frequency or high frequency induction heating, flame heating and reverberatory furnace heating. The heating method used depends on the requirements of the formed product and the energy situation.
