Pipe Insulation Techniques – Perlite insulation is often used where water entering the insulation system can cause corrosion or process problems, such as outdoor piping, fittings and equipment.
Rockwool insulation is used for thermal insulation of pipes that need to be disassembled, such as valves, flanges, tanks, reservoirs, pumps, etc.
Pipe Insulation Techniques
Insulation work must be carried out in accordance with the approved work safety plan and local environmental regulations.
Soundproofing Pipes & Pipe Lagging
Do the work in such a way that noise, vibration and other disturbing effects are kept to a minimum. Comply with all applicable regulations and apply all environmental regulations.
Necessary barricades, safety signs and warning lights must be placed at the intersection between the public road and the access road.
All site engineers and workers receive training in accordance with the safety plan. The contact details of the hospital, police station and other related authorities are given to the engineers so that they can take the necessary measures on the spot.
The monolayer must be installed tightly and tightly. The two-layer layer should be installed in separate layers, which are single-layer, the second layer should be staggered to the first, so that overlapping seams are avoided.
Monitor Corrosion Under Insulation (cui)
Insulation applied to studs, secured with quick washers. The studs must then be bent to the washers (do not cut the studs). The standard length of the needle is 38 mm beyond the surface of the insulation.
Insulation on slabs or vault lath to be tapped on studs at approximately 305mm x 305mm centres.
For valves and fittings 4″ or larger, the insulation shall consist of either (a) preformed insulation manufactured for the particular fitting or valve, or (b) preformed pipe insulation mitered or cut to fit the particular fitting or valve.
The insulation on the pipe adjacent to the flanges should shrink back enough to allow the flange bolts to be removed later.
Coaxial Pipe Elements In Caepipe For Jacketed Piping Analysis
Flanges shall be covered with oversized insulation of the same type and thickness as the adjacent pipe insulation and shall overlap the pipe insulation by at least 51 mm.
Before installing any insulating material (rock wool sheet or rock wool covering, high-temperature rock wool cross-section pipe insulation), the entire pipe surface must be carefully cleaned.
The material of the appropriate thickness must be tightly clamped layer by layer with stainless steel wire. The diameter of the wire depends on the outer diameter of the insulation pipes, according to the table below.
After installing the insulating covers, the entire gap of the joints must be filled with a sealant of the same quality as the insulating covers.
What Are The Key Benefits Of Pipe Lagging For Your Property?
In the case of multi-layer installation, all longitudinal and lateral seam lines must not be in the same line. The upper longitudinal seam lines are at least 15° away from the lower longitudinal seam lines, and the longitudinal seam lines of each layer are higher and at least 15° apart from the lower longitudinal seam lines, and set the longitudinal seam lines of each layer. the top and bottom distance should be greater than 100 mm.
The protruding plate (flat aluminum plate) must be installed along the longitudinal line of the pipeline with an overlap greater than 15 mm and fixed with screws (plate head).
The outer sheets should be overlapped downwards to prevent rainwater from entering. Adjust the side seam lines, the outer plate should overlap by more than 50mm with the jagged joints at the end of each plate, see figure below.
Horizontal and vertical pipes must be insulated with ring supports to prevent slippage between the insulation material and the lag.

Unless otherwise specified, ring supports must be used for all pipelines with an outer diameter exceeding 150 A and an insulation thickness exceeding 75 mm, see the figure below.
Outdoor pipes must be sealed with a seal to prevent rainwater from entering from pipe hangers and hanger bars, see figure below.
Elbows are generally insulated with the same calcium silicate and rockwool pipe casing or blanket as for straight pipelines.
The material must be cut according to the angle of the bend and installed properly to avoid large gaps at the seam lines.
How To Insulate Water Supply Pipes
When installing the insulation material on the elbow, the insulation surface must be completely cleaned, and the material cut along the bend angle must be properly fixed and clamped with stainless steel wire.
In the case of multi-layer insulation, neither longitudinal nor lateral seam lines may be placed in the same place. All seam lines must be staggered, see figure below.
Where insulation is impractical, such as socket-type elbows, rockwool blankets should be installed and tightened with stainless steel wires to provide a snug fit around the angle.
In the case of multi-layer insulation, the individual seam lines cannot be located in the same position both longitudinally and laterally. All seam lines should be staggered.
Clever Uses For Pipe Insulation That Have Nothing To Do With Plumbing
In order to lag behind insulated elbows, the top plate must be overlapped by at least 15 mm, fixed with screws (panhead) along the longitudinal line of the pipeline.
For perpendicular joints from the longitudinal pipeline, the sheet must be miter-cut and tensioned with threaded screws (plate head). See the figure below.
For elbows with small bending angles, which are impractical to use standard battens, such as application of swed laging, elbow-shaped cover or prefabricated branch cover can be installed.
The rockwool blanket must be applied continuously from the straight pipelines, adjusting the thickness of the blanket so that there are no connection gaps.

The branch must be installed in the same way, so that the one-piece installation remains without connection joints.
The box valve cover, prefabricated from lagging plate lined with rockwool insulating material, is to be installed.
The insulation thickness of the box must be the same as the pipe insulation, and the overlap size between the valve cover and the insulated pipe must be the same as the pipe insulation thickness while keeping the one-piece installation method. See the image below.
Insulation and insulation shall be installed in the same manner as pipe insulation, but the connection joints may be removed for repair and maintenance purposes.
The Importance Of Pipeline Insulation
To insulate and lag the flanges, the pre-manufactured cylindrical flange cover is made of aluminum sheet lined with rock wool.
The clearance between the flanges and the insulation covers must be long enough to allow the flange bolts to be removed in any direction for repair and maintenance purposes.
The insulated pipes and the flange cover must be overlapped to the same thickness as the pipe insulation. See the image below.

The aim of this study was to determine the effect of optimal pipe insulation thickness on energy savings and air pollution under greenhouse conditions. In this regard, we implemented an optimization model based on life cycle cost analysis (LCC) using the P1–P2 method. Three fuel types, coal, natural gas and heating oil were tested with nominal pipe sizes of 25-65 mm and hot water was used in the system. Our results showed that the highest insulation thickness (0.807 m), the highest energy savings ($62.351/m) and the lowest payback time (0.502 years) were achieved with the 65 mm pipe size of the heating oil. Overall, insulation minimizes heat loss through heating pipes, resulting in economic and environmental benefits. In this study, fuel oil was identified as the best saving option. Therefore, the CO emissions when using fuel oil
Energy conservation is critical for any country’s economy, especially for Turkey, which is heavily dependent on imported energy. The growing demand for energy due to Turkey’s growing economy and population has led to an increase in the country’s dependence on imports [1]. Most of Turkey’s natural gas consumption is natural gas imports, while domestic oil production accounts for most of it
