Technolloy Inc. is the first Manufacturers, Suppliers & Exporters of the SS 321/321H flanges in Sri Lanka. We make these flanges in various shapes and sizes as per cutting-edge necessities. In affiliations, flanges are used in a grouping of stuff and, in this way, are averaged in an enormous aggregate. We know the essentials of such affiliations; in this manner, we make a substitute kind of flanges as per the need.
Flanges we manufacture follow the set present day, public, and for the most part manage everything. Stainless Steel 321H is a titanium-sealed austenitic Stainless-Steel high in carbon content. This SS 321/321H flanges shows the best disintegrating resistance property. Basically, this mix is known for its oxidation resistance up to 1500 F. Notwithstanding, this grade shows low-temperature strength. Another fundamental part is the intergranular weakening deterrent. High grouch as well as strain break properties of this grade make it a sensible thing.

Because of the tremendous properties of SS 321/321H flanges, they are generally used in the flying application, totaling and gearing in food making due to waste treatment plants, Stainless Steeling, and petrochemical management. What's more, these are used in the gas, drug, heat exchanger, condenser, and pound paper industries.
Different sorts of flanges we manufacture are scene blind flanges, SS affiliation weld flanges, SS weld neck flanges, and SS ring joint flanges. We furthermore change the SS 321/321H flanges in custom closures. The materials we use are totally safe and contamination-free. The thing is openly attempted and evaluated by the appraisal pack. Documentation, test confirmation, and packaging are done.
Squeezing of the thing is done in absurd materials like poly sacks and wooden boxes. We ensure no scratch or mischief is done to the thing during transportation. Similarly, we guarantee that the thing will be completely finished on time. We, close by the thing, offer a few certifications and reports to the clients to ensure that what we pass is freed from degradation and created according to cutting-edge standards.
Our thing can persevere through the high-temperature environment of the business and is strong, so it might be used in broadened-length applications with no mischievousness.
