Liquid filtration tubes from
plastic and stainless steel
Marshall Manufacturing Company, USA,
provides custom machined plastic and
stainless steel tubular components with
precisely drilled holes and precision OD
and ID features for use in water and other
liquid filtration and RO systems.
The company has hole making capabilities
for drilling up to 296 holes in 6 seconds in
tube components with ±0.005" hole-to-hole
accuracy and ±0.010" accuracy between
the first hole in a row to the last hole in a
row.
Roundness on tube outside diameters (OD)
and inside diameters (ID) can be held to
0.0005" when required, in addition to similar
tolerances on flat tubular part features such
as mounting flanges.
Tube materials include stainless steel,
PVC, CPVC, ABS, Polysulfone and others
in lengths to 96" and diameters from 0.5"
up to 4". Up to 72 holes with 0.75" spacing
can be produced in a single drilling cycle.
Up to 48 holes with 1" spacing can be
produced in a single drilling cycle.
Innovative technique for tube perforation
The Joint Perforating Company (JPC), UK, has developed a new perforating process.
Traditionally, perforated tube is manufactured through a lengthy operation starting with
flat strip, and going through four stages before reaching the end result.
JPC’s process perforates pre-formed tube in one operation, which the company claims
saves time, reduces costs, and provides an end result that visually enhances the
product.
Using the latest manufacturing technology, the company provides perforation of a variety
of materials, including stainless steel, titanium, mild steel and aluminised zinc coated
steel from 32mm to 80mm outside diameter, in lengths up to 1,000mm. The company’s
tool design also allows tube perforation in various patterns that can be tailored to
customers’ requirements.
JPC also offers a full range of in-house manipulation and bending services, and is able
to offer fully finished parts without using sub contract suppliers. This allows the company
to have total control of the product from start to finish, ensuring both consistent product
quality and reliable on-time deliveries.
The company has its own transport fleet, and operates almost daily despatches to
mainland Europe.
