Pressure Piping Construction
Every qualified welder will stamp his symbol on work completed by him in the following manner. The mark will be placed at one-meter intervals along the joints and seams of each separate weld. No job is insulated or covered until it is inspected and the stamping is readily visible.
Outweld Industries Inc. can produce 3500 WDIF inches per week.
OutWeld Industries Inc. can produce 15,000 KG structural per week.
• All pressure piping equal to or larger than 7.6 cm is welded with the electric arc process
• When pressure piping is made of steel lighter than Schedule 40, the welded fabrication will use no thread joints and will have a working pressure greater than or equal to 690kPa (100 p.s.i.g.) used to calculate the required thickness of the Code formula.
• No threaded joints are used for welded fabrication of steel piping used for water having a temperature of 104° C (220° F) or more than 600 kPa or steam above 1380 kPa (200 p.s.i.g.) Threaded joints are sometimes used with Schedule 40 pipes for steam up to 1380 kPa.
• Seal welding approved by the inspector may be used in threaded joints but is not considered as contributing to the joint's strength.
Many more regulations must be met. Our pressure piping construction is done by certified personnel who adhere to all rules.
