Tube Welders

Socket weld flanges, also known as SW flanges, have a recessed area (like a shoulder) in the flange bore. This shoulder serves as a guide to set the depth of the pipe that is inserted into the flange. Socket weld flanges are a less common but equally effective connection for flanges that require less overall available space than a traditional weld neck flange, with a counterbore in the center to allow for a clean weld of pipe into the socket. The advantage of socket weld flanges is their simple design; they are well- suited for small pipe size applications, and for non-critical applications, e.g., non-hazardous systems; they are not suitable for highly erosive or corrosive systems. Socket welded flange including RF type and RTJ type, which like other types of welding flanges (slip-on, weld neck, or blind flange). Socket Weld Flanges Application: Socket weld flanges are commonly used in high-pressure piping systems such as chemical processing, petrochemical refining, oil and gas, and power generation systems. These flanges efficiently connect pipes to valves, fittings, and equipment while offering high reliability and safety. In some instances, socket weld flanges are used in small-bore piping systems such as steam, air, water, and gas pipelines where high pressure and temperatures exist. Key Features: Material: Manufactured using superior quality steel, offering high strength, durability, and corrosion resistance. Sizes: Available in diverse sizes to accommodate various pipe diameters. Custom sizes also available on request. Standards: Complies with ASME B16.5 and B16.47 standards, ensuring high-quality and compatibility with a wide range of pipe fittings. Design: The recessed design of the socket weld flange allows for precise alignment of the pipe and flange, reducing the risk of leakage. Applications: Perfect for high-pressure applications and smaller pipe sizes. Widely used in industries such as oil & gas, chemical processing, power generation, and more. Socket welded flange including RF type and RTJ type, which like other types of welding flanges (slip-on, weld neck, or blind flange). Socket Weld Flange vs Slip On Flange Socket welded flange shape is similar to slip on flange, differently it has a shoulder at the inner bore. Slip On Flange – No shoulder at inner bore. Socket weld flange static strength is equal to slip on flange, but it’s fatigue strength is 50% higher than the double welded slip on flange.

Blind flanges are used to close off the ends of pipes, valves, or other equipment, providing a secure seal. Blind Flanges – The Essential Pipeline Closure Solution What Are Blind Flanges? Blind flanges (also termed “closure plate flanges”) serve as permanent or temporary termination points in piping systems. Unlike standard flanges, they feature a solid center without a borehole, creating an impenetrable seal when bolted to pipe ends, valves, or pressure vessels. At JSFITTING, we manufacture industry-compliant blind flanges in all sizes and pressure classes, offering three sealing face variants: Flat Face (FF) Raised Face (RF) Ring-Type Joint (RTJ) Our Blind Flanges Core Features & Benefits 1.

Steel pipe Slip-On (SO) Flanges are engineered for high performance in low- pressure applications, suitable for petrochemical, oil & gas, and water treatment. Meet ASME B16.5 and B16.47 standards and more. Brand: JS FITTINGS Place of Origin: CHINA Material: carbon steel, alloy steel, stainless steel Standard: ANSI/ASME B16.5, EN 1092, GOST33259, BS, DIN, SABS Surface Treatment: anti-rust oil, black painting, yellow painting What is a slip-on flange? Slip-on flanges, also known as ‘hubbed flanges’, have a hub with a very low profile. This slip-on flange is usually connected to a pipe by one or two fillet welds (one outside the flange and one inside the flange), it is, however, possible to use only a single weld. The connection is typically secured with two fillet welds—one on the outer and one on the inner side of the flange. For less critical applications, a single external weld can suffice. This welding method, however, does not create a full-penetration bond, which makes slip-on flanges the ideal choice for lower- pressure and lower-risk environments. Their design makes them a common sight in utility lines for cooling water, firefighting, low-pressure compressed air, and process lines carrying substances like steam, oil, and gas. A key design feature of a slip-on flange is its internal diameter, which is slightly larger than the pipe’s outer diameter, enabling the “slip-on” fit. While their weld integrity is lower than that of a welding neck flange, they offer a significant advantage in tight spaces. However, if a welding neck flange cannot be used due to space limitations, a slip-on flange may be a suitable alternative. When you need a robust and dependable connection, quality is non-negotiable. Our slip-on (SO) flanges are designed to slide over the pipe and be welded securely, creating a lasting seal. Every flange we supply conforms to the rigorous ASME B16.5 and B16.47 standards, ensuring your system meets critical safety and operational requirements. Key Features: Material: High-quality steel that ensures durability and resistance to corrosion. Sizes: Available in a range of sizes to fit different pipe diameters. Custom sizes can also be created upon request. Standards: Manufactured according to ASME B16.5 and B16.47 standards, guaranteeing quality and compatibility with various pipe fittings. Ease of Installation: Slides easily over the pipe and secures with welding, providing a robust and reliable connection. Applications: Ideal for use in lower pressure applications and suitable for industries such as petrochemical, oil & gas, water treatment, and more. Choosing the Right Type of Slip-On Flange for Your Project SO flanges are available in two primary designs, each engineered to solve specific challenges within a piping system: 1. Standard (Raised Face) Slip-On Flanges This is the most common type, featuring a “raised face” on the sealing surface. This slightly elevated platform is crucial because it concentrates the bolt-tightening pressure onto the gasket, creating an exceptionally reliable seal. This design is highly effective and recommended for low-pressure systems where preventing leaks is a top priority. 2. Lap Joint Slip-On Flanges The lap joint configuration consists of a flat-faced flange that works with a separate backing flange and a lap joint stub end. After the stub end is welded to the pipe, the backing flange can slide and rotate freely. This clever design offers unmatched flexibility, simplifying the alignment of bolt holes during installation or maintenance. It’s the perfect solution for systems that require frequent dismantling or those that experience thermal expansion and contraction. Trust JSFITTINGS for Industry-Leading Flanges!

A lipid molecule is added to a peptide sequence during lipidation, a peptide modification process. Since lipopeptide in skin care can be used instead of potentially harmful adjuvants while still eliciting a thorough immune response, they are particularly interesting for vaccine development. Because synthetic peptides by themselves are insufficient to elicit an immune response, immunoadjuvants are frequently used to strengthen the reaction. In the development of peptide vaccines, alternatives to the traditional Freund's adjuvants have met with some success. These include conjugations to viral and bacterial carrier proteins, immunostimulating complexes, and branching multiple antigenic peptides (MAPS). After Hopp and colleagues discovered in the early 1980s that a peptide conjugated to a dipalmityl-lysine moiety increased anti-hepatitis surface antigen response, lipopeptides were initially used in vaccine development.[1] This result is explained by the fact that, despite the possibility of short peptides containing cytotoxic T cells (CTL) that bind to MHC class I molecules, they are unable to prime CD8+ T-cell responses in vivo. This was further supported by Rammensee and colleagues, who demonstrated in the early 1990s that an influenza lipopeptide (without the need for an adjuvant) evoked CTL responses but the comparable peptide without lipid conjugation did not. Myristic acid, palmitoyl, dipalmitoyl, geranyl, farnesyl, geranylgeranyl, and other lipids are only a few of the lipids that may be linked to nearly any peptide sequence by CPC due to its significant experience and knowledge in the synthesis of peptides containing lipid moieties.
