To find acetylene refills near you, start by checking local welding supply stores, as they typically carry a variety of gases, including acetylene. Major suppliers like Airgas have locations nationwide and offer both refills and new cylinders. Alternatively, search online directories or maps services (such as Google Maps) using keywords like "acetylene gas refills near me." This will provide a list of nearby options with customer reviews and contact information. If none of these methods yield satisfactory results, consider reaching out to local hardware stores or industrial supply shops; while they may not refill cylinders themselves, they can often point you towards someone who does.
Polyethylene (PE) water pipes, widely recognized for their flexibility, durability, and resistance to corrosion, come in various dimensions tailored to diverse applications. The dimensions of PE pipes are generally characterized by their outside diameter (OD), wall thickness (which affects the pipe's pressure rating), and length. Standard diameters range from about 16mm up to 1200mm, supporting a variety of pressure ratings from PN4 (for lower pressure systems) up to PN25 or higher for high-pressure applications. Pipe thickness typically increases with the pipe’s diameter to maintain structural integrity under pressure. Lengths can vary, with some coils available in lengths up to 100 meters for smaller diameters, facilitating easier installation with fewer joints. For larger diameters, sections might be around 12 meters, expected to be fused together during installation. It’s crucial to select the appropriate dimensions based on the application’s specific requirements, including the expected pressure, the fluid being transported, and environmental factors.
Connecting cast iron to PVC is a common plumbing task, particularly during renovations or repairs where old and new materials meet. The most reliable method is using a rubber coupling, often referred to as a no-hub coupling, which is designed for this purpose. Ensure the cast iron and PVC pipes are cut cleanly and any rough edges are smoothed. Slide the no-hub coupling over the end of one pipe, then insert the other pipe into the coupling. The coupling should have stainless steel clamps; tighten these clamps with a screwdriver or a wrench, securing both pipes in place. This method creates a strong, leak-proof connection that accommodates slight differences in size and allows for some movement and flexibility between the two materials. Always check local plumbing codes to ensure compliance.
