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.
