All-Weld Company Limited products

This CRN certified horizontal pressure vessel was fabricated for a refinery in Western Canada. The pressure vessel contains a woven mesh mist eliminator and a boot type sump to separate entrained liquids from a pressurized gas stream. Pressure vessels fabricated for the petrochemical marketplace are required to meet stringent quality standards and non-destructive testing criteria which are over and above the ASME Code Section VIII, Pressure Vessel Standards

An Air Receiver is the simplest form of Pressure Vessel and can be configured in any size or configuration. Typically, a length to diameter ratio between 1.5 to 1 and 2.5 to 1 is economical for low to medium pressure applications.

Here is an assembly for purification of process air. The air is subjected to high temperatures which ignite and destroy flammable particles. A horizontal heat exchanger filled with incoming process air is heated by the outgoing purified air. The top tank is an oxidizer dwelling chamber with a natural gas burner to ignite and assist in the self-destruction process. Due to the, high temperatures involved both vessels are internally insulated. The purified and unpurified air are separated by a novel design that allows for the thermal expansion of the tubes. All-Weld can fabricate to any specified diameter and length, and has shipped these products to the USA, Canada, and Europe. The majority of these heat exchangers are manufactured from carbon steel with internal ceramic insulation, however in some cases stainless steel or high nickels with external insulation are utilized instead.

This 16″ diameter 65,000-pound stainless steel Pressure Leaf Filter contains a 24″ diameter shaft that was machined by All-Weld. The painted filter leafs were supplied by our client and installed by us prior to test running the assembly. It is an ASME Vessel used for filtering wood particles from the liquid in a pulp operation in Sweden.
