Heat Exchangers
Heat Exchanger
Shell and tube type heat exchangers are highly complicated equipment and critical parts of any industrial plant to provide best thermal performance. Experience and right manufacturing methods play important roles for design and quality. Our fabrication facility is equipped with the latest technology equipment with dedicated fabrication halls for carbon steel and white products; such as stainless steel, aluminum and special alloys, to cater our customers’ needs. We are capable of designing and manufacturing following type of heat exchangers:
- U-tube type heat exchangers
- One pass straight fix-tube heat exchangers
- Two or multiple pass straight fix-tube heat exchangers
- Floating head heat exchangers
Rubber Lining
Rubber lining is a common method of protecting pressure vessels or storage tanks internal from highly corrosive chemical and abrasive environments. ERGIL uses various kinds of rubber material; such as nitrile, neoprene, viton, EPDM, Ebonite, chlorobutyl, bromobutyl, food grade rubber lining, and Triflex rubber lining, depending on the application.
Overlay Welding
ERGIL provides in house overlay welding (weld cladding) for pressure vessels, heat exchangers, and process equipment. It is a cost effective way of dealing with corrosion, however requires a great deal of experience. Overlay welding application is not a new technology, but using the correct welding, consumables, welding specifications, and machinery have to be chosen correctly. Depending on the main material, stainless steel overlay welding reacts differently.
Testing
ERGIL is capable of testing pressure vessels and storage tanks for strength and leaks in-house. ERGIL’s specially dedicated place for hydro-testing pressure vessels provides sufficient safety measures to test and inspect vessels with up to 300 bar test pressure. ERGIL is also capable of inspection and testing of static vacuum insulated cryogenic pressure vessels used in the storage of refrigerated liquefied gases.
Coating & Painting
ERGIL’s in-house shot-blasting and painting capabilities provide unique solutions for both onshore and offshore applications. Painting shop has a heating room that provides desirable results in much faster time. It is equipped with conventional, HVLP, airless, air-assisted airless and electrostatic spray equipment. This equipment is used to apply conventional coatings such as alkyds, epoxies, zinc riches, polyurethanes and water borne products. Ergil can provide NACE inspector coating and painting quality approvals upon request.
Sour Gas
Whether it is a natural gas, or a crude oil project, ERGIL has vast experience dealing with hydrogen sulphide (H2 S). Thanks to ERGIL’s well reputed quality assurance system, we have carefully picked vendors that provide material; such steel plates, fittings, gauges, instruments and valves for sour gas services. ERGIL’s quality control is trained and experienced with NACE MR0175 & NACE MR0103, which provides guidelines for sour service applications.
Post Weld Heat Treatment (PWHT)
ERGIL is able to apply in-house post weld heat treatment for pressure vessels and welded parts up to 4600mm in dia and 18000mm in length. It is one of the most critical processes in manufacturing process vessels. Having an in-house PWHT system provides a unique opportunity for ERGIL to cater all project needs in the most cost effective way with shorter manufacturing time.
