Tube and Pipe


This sector manufactures pipe and tube value added products for exhaust systems, including catalytic converters. The moders automobile exhaust system is increasingly made almost entirely of stainless steel and the manufacture of emission control systems in South Africa is one of the fastest growing industry sectors in the world.

Founded on the growth and development of catalytic converter manufacturing, the auto emission industry is now supplying hightly sophisticated systems to many of the world’s vehicle companies.

Production of catalytic converters now exceeds 10 million units a year, which means that South Africa now produces 10 percent of the worlds catalytic converters, representing a R1 billion a year export business. This industry consumes 30 percent of primary material supplied into the domestic market by Columbus.

Growth in the industry is driven by the Motor Industry Development Programme (MIDP), which is aimed at making the local automotive sector internationally competitive growing exports, modernising the industry and increasing production volume and scale.

The programme was introduced in 1995 and extended until 2007 by The Department of Trade and Industry (DTI). The sector is now awaiting the outcome of a review of the MIDP review process, which is expected to have a major bearing on the short-term prospects in the automotive sector.

The sector also supplies products for the architectural, energy, food and beverage, petro-chemical and industrial industries. It produces ornamental tube manufactured to A554 standards used in architectural applications, schedule pipe manufactured to A213 standards used in petro-chemical and industrial applications, specificatoin tube manufactured to A249 and A269 standards used in applications such as heat exchangers.

Member companies manufacture longitudinal and spiral-welded pipe and tube in a variety of grades and diameters or wall thicknesses, including grades 409, 430, 439, 444, 304, 304L, 316, 316L, 3CR12.

The welding processes include TIG, MIG, High Frequency and Laser.

Pipe and tube is produced to International Specifications A including ASTM 249, A268, A269, A270, A312 in accordance with ASTM A450.

Tube is produced for the decorative (balustrade) architectural industry generally in accordance with the dimensional tolerances shown in ASTM a 450/A 450M -02. Various finishes such as 180 grit – 240 grit, 400 grit are available.

Capacity throughout the sector is almost fully utilised. Import volumes have surged due to favourable market conditions.

Infrastructural spend, a major influence on this market, is expected to drive volumes, but the impact of the nickel price and other alloy surcharges is behind increased subsititution of stainless steel with other products in the pipe and tube sector.
