  Our Services Austenitic

  Austenitic stainless steels have high ductility, low yield stress and relatively high ultimate tensile strength, when compare to a typical carbon steel. A carbon steel on cooling transforms from Austenite to a mixture of ferrite and cementite. With austenitic stainless steel, the high chrome and nickel content suppress this transformation keeping the material fully austenite on cooling (The Nickel

  Our Serices Welding Quality

  Visual Inspection (VT) Visual inspection is a non-destructive testing (NDT)weld quality testing processwhere a weld is examined with the eye to determine surface discontinuities. It is the most common method of weld quality testing. Advantages of nondestructive weld quality testing: Inexpensive (usually only labor expense) Low cost equipment No power requirement Quick

  Welding Welding is basically the mixing of abase metalwithfiller metal. Filler material is melted at high temperature through a consumableelectrodeand provides the relevant bonding strength. Filler metal and base metal are bonded together in one solid body. A good quality weld is at least as strong as the base material(s) being joined. Preheating Preheating is

  Welding Procedures are the guidelines used to perform a weld. They are designed to provide a record of the welding variables used and the inspection results obtained during the procedure qualification test. They can also provide the instructions for the welder to use in production in order to produce acceptable welds. Usually welding procedures are developed in accordance with a welding code or standard,

  At the end of construction, and following commissioning tasks such as water flushing, water should always be present in petroleum processing equipment. Whenever this water may subsequently lead to an operational problem, or if equipment may be damaged, it is necessary to perform a drying-out operation. There are several different reasons for drying-out depending upon the type of equipment and

  Preheating involves heating the base metal, either in its entirety or just the region surrounding the joint, to a specific desired temperature, called the preheat temperature, prior to welding. Heating may be continued during the welding process, but frequently the heat from welding is sufficient to maintain the desired temperature without a continuation of the external heat source. The interpass temperature,

  Have you heard of post weld heat treatment (PWHT)? Of course you have. If you are involved in welding you have definitely heard this term. But what is PHWT? When is PWHT required? What temperature should PWHT be done at? Heat treating of materials can be a very complicated subject, but when it comes to heat treatment after welding it boils down to a simple concept: PWHT is done in

  Preheating Heat treatment of welds is a critical activity which needs to be carried out before and after the welding process. Heat treatment before welding (Preheating) is necessary to bring the base weld metal at proper temperature. No welding shall be performed without preheating the joint to 10°C (50°F) when the ambient temperature is below 10° C. Preheating requirements for
