Custom Pipe Spools
Custom pipe spools are fabricated from a number of raw pipes and pipe fittings (elbows, flanges, tees, etc). Raw pipes are cut to the required sizes and moved with pipe fittings to a fitting table, where some of the components are fitted together. The resulting sub-assembly (part of the final pipe spool) continues with welding operations.
Whatever size at whatever tight tolerance of custom made pipe spools you demand, SEATHER here is sure to have it!

Custom Made Pipe Spools: The Ultimate Guide
The custom pipe spool is an assimilation of piping components, which is prefabricated in a piping shop, for installation in the field. They are often flanged to facilitate the connection to other spools.
When you choose to buy custom made pipe spools, there have some important points we need to know before we get started.
What are Custom Pipe Spools?
The custom pipe spool is a relatively short component, consisting of a pre-determined length of pipe welded to a specified pipe fitting (tee, elbow or reducer) or valve (gate or ball). The flange is usually welded to each end of the pipe.
Due to the excellent corrosion resistance of stainless steel and nickel alloy, the pipeline is not easy to rust, damage or accumulate debris by wear.
Custom Pipe Spools Applications
Custom pipe spools are used in many fields, such as:
Heat exchanger
Chemical fertilizers industry
Dairy and food processing
Power plants
HVDC systems and facilities
Textile machinery
Modern architecture
Pharmaceuticals
Food processing industry
Water treatment facilities
Synthetic fibers
Pulp and paper make industries
Refinery and petrochemicals
Precision instrumentation
Instrumentation and industrial valves
Fluid tubing systems
Nuclear power
Building installation
Mechanical fittings connection
Vehicles and ships construction
Bridges, tunnels and railways
And so much more!
Features of Custom Pipe Spools
- Excellent oxidation resistance at high temperatures.
- Polishing bright finish.
- Raw material nickel alloy and stainless steel which is prime quality.
- Uniform on the size and high breaking load to guarantee the stable. When you working with SEATHER, the specialty and service will impress you so much.
What Are Custom Pipe Spools Surface Treatment?
Surface treatment is one of the major part in whole production.
Different surface finish will be used for different custom pipe spool.
With methods including anodizing, passivation, brushing, polishing, blackened, plating, painting, powder coating, heat treatment, surface phosphating, hot dip galvanizing, other surface treatment, etc.
Key Considerations When Buying Custom Pipe Spools

FAQS
Stainless steel is an excellent material for custom pipe spools production for some reasons.
Firstly, it is corrosion resistant. It will not rust, which is essential because pipes can corrode relatively easily.
Secondly, stainless steel pipe spools are thick and robust, giving them a high load capacity. They can support a lot of weight because of this.
Thirdly, the stainless steel pipe spool is that they are pretty cheap. Therefore, these are the spools to pick if you’re on a tight budget. They are cheaper than nickel alloy pipe spool.
