These pre-insulated pipe supports were manufactured for a Houston based engineering and construction company to complete an on-going project in South Africa. The polyurethane foam insulation is wrapped with a vapor barrier to prevent moisture, and the ends are coated with a monolar mastic paint to seal the pores. The carbon steel fabrication that surrounds the insulation has an elaborate three-coat paint system to help protect the steel from corrosion. This design allows for an integral combination of insulation and structural support in one pipe support assembly. It also minimizes labor in the field in regards to the installation of insulation.
Piping Technology & Products, Inc. recently designed and manufactured 566 pipe shoes for an energy plant in Canada.
These fabricated pipe shoes are manufactured to support pipes. The pipe shoes are fabricated out of A36 carbon steel with sizes ranging from 12 to 36. They have an overall weight of 134,000 lbs.
Piping Technology and Products, Inc. fabricated 4702 carbon steel shoes for various pipe sizes ranging from 2” to 10”. As per customer request, the shoes are designed to accommodate 30 PSI compressive strength. A three-coat paint system was applied for corrosion protection. All supports were liquid dye-penetrant tested at 5% of welds.
PT&P was called on by an energy center in Oklahoma to inspect failing pipe shoes designed for temperatures ranging from 650 to 1065 °F supplied by another company. After thorough inspection, PT&P’s field service representatives concluded that the problem was due to the existing pipe clamps’ inability to firmly grip the pipe during expansion. This exposed the pipes to atmospheric moisture, resulting in both heat loss and deterioration. To alleviate the situation, PT&P designed secured pipe clamps that were bolted and torqued such that the entire pipe shoe would move with the pipe’s expansion. PT&P’s field service team also provided on-site installation of the replacement pipe shoes. The entire process involved stripping of the existing damaged insulation, removal of the failing supports, and installation of new pipe shoes and insulation.
Over 160 pipe shoes were engineered, manufactured, and installed for this energy center. The fabricated pipe shoes, designed for pipe sizes ranging from 12 to 28″ in diameter, are equipped with special base plate and slide bearing plate combinations which allowed axial movement from 1/2″ to 7″ and lateral movement up to 10 1/2″. In addition, they were designed to support a maximum vertical and lateral load of 38,000 lb. and 7,600 lb. respectively.
