Our technicians are experienced with chemical conveying and food processing systems as well as water, wastewater, steam, and condensate, and other process-intensive applications. We have years of experience in performing chemical plant shutdown work around the clock, to meet your schedule.We understand the importance of quality and timely installations, especially when our customer’s production schedule is in jeopardy. Through our “State of Readiness” motto we are able to respond to a customer’s needs both timely and efficiently. Whether it’s a new installation or repair to a system, we are ready for the challenge with professional management and expert craftsmen.Pipe and piping systems are found within many elements of buildings. Numerous people have seen a P-trap below a sink or refrigerant lines routing to and from their residential split system. Fewer have seen the main utility piping routing from a central plant or the chemical treatment systems within a pool equipment room. Each of these applications requires a specific type of pipe to meet the requirements of the codes, physical limitations, specifications, and best design practices

Pipeline Installations

AIS Pipework utilise a wide range of products and materials to ensure the very best quality and performance of work is achieved. We use Polyethylene, ductile Iron, Steel, and UPVC, we have suppliers based throughout the Saudi Arabia and skilled site teams available 24/7 giving us nationwide capabilities.

 

HVAC piping encompasses many different fluids, pressures, and temperatures. This piping can be located above or below ground and route through the interior or exterior of a building. These factors must be taken into consideration when specifying HVAC piping within a project. The term “hydronic” refers to the use of water as a heat transfer medium for cooling and heating. In each application, the water is supplied at a set flow rate and temperature. Typical space heat transfer is completed using an air-water coil designed to return the water at a defined temperature. This results in a specified quantity of heat delivered or removed from the space. Hydronic chilled and heating water are the dominant systems used to condition large commercial facilities.

Water – We install a variety of water based pipe systems to suit the client’s requirements. Whether it be external, internal, above ground or below. We install pipe lines for potable and non potable service, we offer barrier pipe for contaminated ground and pre insulated pipe systems for hot or cold water systems.

Our pipefitters install and repair both high- and low-pressure pipe systems used in manufacturing, in the generation of electricity, and in the heating and cooling of buildings. Additionally, we install automatic controls used to regulate these systems….it’s like hiring your very own pipefitter, with the added convenience of a General Contractor to support their work and progress.

Our general Pipefitting services target:

• Fabrication
• Installation
• Threaded Pipe
• Welded Pipe
• Stainless Pipe
• Carbon Steel
• Copper Nickel
• Sanitary Piping

Today, there are millions of miles of plastic piping with threaded fittings, providing reliable, leak-free service. However, a tiny percentage of those threaded plastic fittings may leak or break. The reason for this is improper assembly of threaded joints.

The right way to assemble a threaded PVC joint-Schedule 40 or 80 is finger tight plus one to two turns-no more. Two turns past finger tight plus the stress of the system pressure is within the tensile strength of one-inch PVC. ([1,788 psi x 2] + 2,000 psi = 5,576 psi).
