EFT innovative 316Ti stainless steel pipe fitting machining technology exceeds german leading fluid connector manufacturer's expectations

316Ti stainless steel pipe

316Ti (ASTM, DIN 1.4571) ferrules for heavy-duty industrial applications.

Everfit Technology CO., LTD. (EFT) is a stainless steel pipe fitting manufacturer that has been supplying 316L stainless steel hydraulic hose couplings and compression fittings to a German leading stainless steel fluid connector manufacturer for over ten years. Two years ago, the client requested 316Ti (ASTM, DIN 1.4571) ferrules for heavy-duty industrial applications. To meet the deadline, flexibility and innovation were needed.

It was a fuel pressure's fitting in the auto parts. At EFT, during the machining process, equipment was relentlessly tested by trial and error, including automatic circular sawing machines, CNC horizontal boring machines, and CNC lathing machines. Also, suppliers' 316Ti was experimented during machining practices to find out which material has the best performance. All the actions taken were to lower the fatigue strength on 316Ti.

For instance, automatic circular sawing machine and 316Ti boring machine were purchased, CNC lathing machine designed with additional functions, cutter and gauge designing for a machining process, and 316Ti material supplier sourcing. In general, 316Ti machining technique was regularly modified based on the outcome. In the end, steel scrap's amount was reduced due to the processing accuracy, productivity was improved, the ferrules were perfectly delivered to the client, and EFT has proved their highly skillful engineering technology to accommodate each client's standards.

EFT purchased material from suppliers in Italy, France, and Korea to improve titanium machining performance.

Because of titanium's distinct properties, this has further complicated the machining process. 316Ti can be strongly influenced by even a slight variation among elements, though all are named 316Ti stainless steel. Without compromising client's fitting quality, EFT insisted on using the titanium alloy that performs the best, regardless of turning, boring, milling, drilling, reaming, tapping, broaching, shaping, shaving, grinding, etc.

CNC Automatic Circular Sawing Machine to Cope with Rigid Titanium Bars

With titanium bars, the force and velocity from the cutting machine determines the cutting accuracy. When it cuts imperfectly, the subsequent procedures - drilling and lathing – are influenced. Therefore, EFT's purchased four new CNC automatic circular sawing machines to increase titanium bar's cutting certainty.

Since then, every cut bar has the same length, perfect flatness, and more importantly, the rest of 316Ti machining productivity is improved.

CNC Boring Operation Machine Leads to High-Performance Lathing Process

With no high-efficiency bore machine, incorrect boring size leads to more machining workload. At EFT, each 316Ti stainless connector is bored with a gauge to enhance its drilling efficiency. Plus, with CNC vertical boring operation machine’s quality boring job, every piece is drilled with the correct size, straightness, and concentricity.

CNC lathing machine leads to High-Performance of lathing process

To shape 316Ti ferrules, cutting, sanding, knurling, and drilling with high precision wasn't easy; there were many worn out knives, titanium steel scrap clustered and dragged machining speed. All these factors had resulted 316Ti fitting with flaws, and to make it right, the engineering team came up with some solutions. By enlarging the pump size and increasing cutting fluid's amount from 15% to 70%, the milling cutter's heat generation was prevented. And because of the high-speed operation, steel scrap was removed fast, which has allowed the lathing from a smaller hole and therefore was more effective. The cutter, after studies, were custom-made to handle titanium's tough surface.

316Ti ferrule's complex machining process is overcome by talented EFT engineering team.

Although challenging, the hydraulic hose couplings and compression fittings were delivered on time, and the quality was impeccable. And because of the high performance of complex machining work, EFT was able to expand their 316 titanium part services in Germany along with France, Israel, and Japan. EFT's technology and know-how, as well as the broad range of services in various industries, allows them to be continuously reached by world-class customers.

Everfit Technology CO., LTD. – stainless steel pipe fitting expert

Based in Taiwan since 1976 and specialized in manufacturing concentric and eccentric reducers, ASME BPE, pipe tees, BPE fittings, PC pumps, vacuum components, valve actuators and valves, and meeting DIN / EN / SAE / BS & standards with stainless steel 304, AISI 316 and 316Ti. EFT is well-known for achieving the impossible; their high-passion engineering team plays an important role overall.

 

EFT's concentric and eccentric reducer machining solutions for a German pharmaceutical client

Rather than using a lathe machine to conduct machining process on concentric and eccentric reducers, which are stainless steel 316L, weight over 30kg and size 6 inches, EFT switched to CNC milling machine with integrated solutions to achieve the German pharmaceutical client's requests and also meet ASME BPE standards.

Stainless steel 316L, 30kg and size 6 inches eccentric reducer is built meeting ASME BPE standards. 

Unlike before, concentric and eccentric reducer can be machined with stainless steel pipes and tubes by applying forming and trimming technologies. Based on ASME BPE -2012, steel bar becomes mandatory for making pipe fittings. Stainless steel bar requires different machining solutions, since lathe machine just can't achieve the goals. Particular for the client's product is that a 6in. 316L eccentric reducer's thickness is uneven, the steel is tough for processing, the machining time is long due to low speed and constant feed rate, and the generated centrifugal force also makes the result unreliable.

Eccentric reducer is manufactured by a group of elites with innovative technology.

In the beginning, EFT designed and built a gauge to support reducer fitting's machining process from lathe machine. However, cutting knives got worn out, and machines broke down for days. It took five days just to finish one, let alone 100 of them! EFT needed to increase the productivity.

As a result, to facilitate concentric and eccentric reducer's production speed along with high precision, EFT engineering team decided to use 100% automatic CNC milling machine, incorporated with a specially designed cutter to handle the concentric and eccentric reducer's machining operation. With the whole eccentric reducer sitting on the machine platform, centrifugal force issue is eliminated, the processing speed is faster, and the product accuracy is 100%. The large size eccentric reducer's machining process is no longer an issue, and they are capable of manufacturing size 1/2", 2/3", 1", 1.5", 3", 4", 6", and more. EFT's industrial standard concentric and eccentric reducer allowed them to sell in the semiconductor, pharmaceutical, and food and beverage industries with solid reputation.

To make stainless steel fittings with 100% precision, gauge and mold design are critical. At EFT, they are constantly delivering solutions to meet clients' standards.
