Hardware material
- Steel Pipe
The standard steel pipe is either of electric resistance welded and /or seamless construction. For nominal bore sizr 1/2″ to 10″ inclusive pipe Conforming to ANSI B36.10 Sch 40 Dimensions are used. For above size, material and others standard up on request - Flanges confirms to ANSI standard forging flange, ASTM A105 and A106 for pipe components. PTFE lined pipes supplied with one loose & other fixed flange, for elbows and others fittings will be supplierd fix & fix flange. However, it can be supplied per individual customers requirement
- Fittings : The ANSI Standard steel pipe fittings ASTM A234, SS material available up on request.
- Finish : All external surface of carbon steel housing is painting finished. For Stainless steel shall be accordisng up in customer request.
Design Requirements
Dimension
- Nominal PTFE liner Thickness of Piping
- Tolerance
Pipe in length | +/- 3.2 mm: Flange Bolt hole alignment | +/- 1.6 mm
Venting / Vent Hole
Each pipe and fitting shall be provided with a venting system that will release any gas between the liner and the housing. Each pipe & fittings has 2 vent holes with 2mm diameter at both end.
Inspection Test
Hydrostatic Test
All PTFE lined pipes and fittings are subjected to 29 Bar (425 psig) for hydro pressure test at room temperature base on ASTM F1545. Any leakage is observed from vent holes and pressure gauge
Spark Test
Base on ASTM 1545 this test performed 15 kV nondestructive spark test for all the pipes and fittings. Detect such as cracks, pin holes in the liner will be observe from audible and visible from the testing equipment
Tank Lining
Tanks & Vessel hardware material is Carbon steel, Stainless steel or any other material base on requirement. For Liner using standard thickness of 3 mm PTFE sheet or other Fluoroplastic liner material which suitable for application require
