PERMANENT STEEL MANUFACTURING CO.,LTD

Forget about your water heating problems by switching to a stainless steel boiler made to order by the Profinox team! We meet your needs and the most demanding and particular requirements. A coil stainless steel boiler or a woodfired stainless steel boiler made to order by our team will certainly differ from commercially available products because The stainless steel boiler will be created to fit the volume and dimensions you need, depending on the space in which it will be placed; we use only quality materials for our products; The quality of our welding recommends us. The Profinox team manufactures a variety of boilers, all with a very long service life Coil Stainless Steel Boilers boilers with 1 or 2 coils; WoodFired Stainless Steel Boiler Since 2005, we have been providing our domestic and international customers with premium quality products and complex services in stainless steel machining.

Economizer is a product which provides fuel saving and boiler efficiency in boilers, steam boilers, hot water boilers and hot oil boilers by using the heat of the flue gases in order to increase the temperature of the feed water (and fluids) in the system. The payback amortization of economizers varies depending on such factors as the capacity of the system, efficiency of the boiler, and its application areas. The pay-back period of an efficient economizer varies between 3 – 18 months.

TRIS supplies tubes of various specifications and steel grades for petrochemical plant construction. TRIS has supplied not only straight tubes but also Seamless Coiled tube with longer length. The seamless coiled tubes have many benefits with reducing welding pointsand minimized the leakage points and helping to reduce the construction period in dramatically. In 2013, TRIS developed the Seamless Coil Tube. Now, TRIS can handle various steel grades such as 904L, C-22, Incoloy825, Super Duplex etc. of Coiled Tube and Straight Tube. The longer length of Nickel alloy coiled tube is usedfor chemical injection, hydraulic control, gas detect line etc. in Oil & Gas industry. In addition to the heat exchanger tubes of TRIS of chemical plant used in severe environmentsprovide the most efficient operation conditions by stable quality control and various Ni alloys.

Since UHP (Ultra High Purity) tubes with high corrosion resistanceas well as good internal roughness and cleanliness are needed in Semiconductor field,TRIS provides tube OD size from 1/4 inch to 2 inch for EP (Electro Polishing) process with high quality. TRIS is a supplier to Global Semiconductor manufacturers through EP companies. Since 2004, TRIS has been supplying more than 1 million meters of seamless clean BA tube every year.
