Vermeer Thermex Thermal Mainenance System

• Made of carbon steel SA-179 – P235GH Gr B boiler tubing, or optional SA-312 grade TP316;
• Boiler tubing is deformed to a rectangular section and secondly deformed one large side of the element to meet the adjacent radius of pipe;
• Designed, classified and manufactured according the ASME Code, Section VIII Div 1;
• Welding is certified to the ASME Code, Section IX;
• Bursting-tested” and certified by Lloyds for use at 35 barg steam;
• Material Certification according type 3.1 or EN 10204:2004;
• The TE elements are pneumatically tested;
• Painted with a (50 – 100 µm elements) Inorganic Zinc primer upon request;
• Inlet and outlet connections 1/2” Swagelok or equal double ferrule weld-adaptors/connectors;
• 1/2” pre-insulated tubing to interconnect the TE elements and other in-line components;
• Band-it for pipe sizes up to 6” and C/S metal straps for sizes of 6” and up;
• Vermeer Thermex heat transfer compound is used to improve heat transfer and avoid air gaps.

Engineering

• Steam consumption and thermal analysis as per design requirements of this bolt on heating system will be done at start of the detailed engineering;
• Steam load calculations will specify the exact amount of circuits, steam supplies and condensate returns. Optimization of manifolds quantity and tubing runs amount will be part of this exercise;
• Engineering/mechanical design of the bolt on heating system during detailed engineering will result into Installation Drawings and Manufacturing Drawings for Approval;
• 3D-model review together with client to identify possible clashes with existing structures, pipes, etc., and to identify the optimum location of manifolds;
• AUTOCAD and 3-D format drawings in compliance with clients 3-D model.
