We, LAWAI INDUSTRIAL CORPORATION have been in centrifugal casting over 30 years in Taiwan.  Hollow Ni-resist cast iron tubes produced by centrifugal casting technique is one of the products we make. 

In addition to stainless steel, ASTM A297 heat-resistant steel and Nickel-based superalloy, Ni-resist is the cast iron with many types we manufacture in very high frequency especially ASTM A436 Ni-resist type 1. 

For us, we regard Ni-resist as a “high grade” cast irons because the corrosion resistance and mechanical properties are much superior than the common cast iron ( unalloyed ductile and grey cast irons).  At our foundry, Ni-resist 1 cast iron centrifugally cast tubes & rings were developed very successfully. 

Why Ni-resist 1 is a premium cast iron?

The proportion of nickel is high of the chemical composition of Ni-resist 1.  Because of the sufficient nickel, the Ni-resist 1 is with the austenitic structure and with the corrosion & oxidation resistance.  Ni-resist 1 is good to resist the corrosion in dilute acids, seawater and the salt liquids.  Also, it has good wear resistance.  Therefore, LAWAI’s Ni-resist 1 cast iron centrifugal casting is the material of Alfin rings(ring carriers) and the sleeves, housings and other key components in oil & gas, marine and pump industries. 

Why LAWAI is your priority for supplying hollow Ni-resist cast iron tubes?

1. Applying centrifugal casting technique. 

LAWAI’s hollow Ni-resist cast iron tubes are produced by centrifugal casting technique which is the cost-effective method to produce hollow and symmetrical products.  Customers save the machining fees and time for doing the drilling process. 

2. Over 30 years’ experience in centrifugal casting in Taiwan.

LAWAI is the only centrifugal casting manufacturer in Taiwan which is able to produce the special cast iron hollow tubes for example Ni-resist cast iron. And LAWAI continues improving and learning in centrifugal casting with local and international companies to ensure each hollow Ni-resist cast iron tubes that meets the standards and expectations. 

3. Stable quality and traceability 

Purchasing the hollow Ni-resist cast iron tubes with LAWAI relieves worries. 

All LAWAI’s hollow Ni-resist cast iron tubes are produced by LAWAI.  LAWAI manufactures and sells the centrifugally cast products by ourselves.  Customer relieves the worries regarding the quality and traceability because each Ni-resist cast iron tube will be marked our logo and grade.  And customers will receive our inspection certificate and the heat number will be stated. 

4. Boutique-sized foundry is more flexible for MOQ. 

LAWAI is the boutique-sized centrifugal casting foundry.  Therefore, we are more flexible regarding the order quantity. The lower quantity order could be made by centrifugal casting technique and the smaller-sized foundry will be the one which is able to do the custom hollow Ni-resist cast iron tubes with low MOQ.  LAWAI’s hollow Ni-resist cast iron tubes are great value. 

5. Taiwan quality is reliable. 

Each hollow Ni-resist cast iron tube manufactured at LAWAI represents the Taiwan power and tradition.  Each centrifugally cast iron tube will be cast not only the liquid metals but also LAWAI team's passion and dream.  The smaller team do the great things and create the high values for various industries.  

Taiwan spirit is work hard and provide the best for customers.  The reliability of Taiwan products is irreplaceable. 

The custom hollow Ni-resist cast iron tubes are exquisite centrifugally cast products manufactured by LAWAI. The fine grained structures and excellent mechanical properties are good enough for your applications!

Please contact us and let us know your demands. 

We are looking forward to producing the hollow Ni-resist cast iron tubes for your projects.
