Introduction
Kalpataru piping is one of the leading manufacturer, suppliers, exporter of stainless steel 304/ 304l/ 304h Shims using high quality of raw material. Stainless steel 304/ 304l/ 304h Shims have high strength and resistance to oxidation, carburisation and other harmful effects of high temperature exposure. The high contents of nickel and chromium in the alloys also give good corrosion resistance. stainless steel 304 was the first of these alloys and it was slightly modified into Incoloy 800H. This modification was to control carbon (.05-.10%) and grain size to optimize stress rupture properties. stainless steel 304l/304h shims was intended for high temperature structural applications. The nickel content makes the alloys highly resistant to both chloride stress-corrosion cracking and to embrittlement from precipitation of sigma phase. The general corrosion resistance is excellent. In the solution annealed condition, stainless steel 304l shims and 304H shims have superior creep and stress rupture properties. Stainless steel 304 shims are used in a variety of applications involving exposure to corrosive environments and high temperatures such as heat treating equipment, chemical and petrochemical processing, nuclear power plants and the paper pulp industry. Heat-treating equipment such as baskets, trays, and fixtures employ stainless steel 304/304l/304h Shims. Chemical and petrochemical processing industries use the alloys for heat exchangers and other piping systems in nitric acid media especially where resistance to chloride stress-corrosion cracking is required. Power plants use them for super-heater and re-heater tubing. We also offer these Products are available in different size,grades, specification & thickness as per the clients requirements.

FAQ’s About Monel Flanges
What is the maximum service temperature for Monel 400 flanges?
Monel 400 flanges can be used up to approximately 550°C (1022°F) in non-oxidizing conditions, making them suitable for high-temperature chemical processing and steam applications.
Can Monel flanges be used with hydrofluoric acid?
Yes. Monel 400 is the industry-standard material for handling hydrofluoric acid at nearly all concentrations and temperatures in de-aerated conditions, which is why it is widely specified for HF alkylation units in refineries.
What is the difference between ASTM B564 and ASME SB564?
ASTM B564 is issued by ASTM International, while ASME SB564 is the equivalent specification adopted by the ASME Boiler and Pressure Vessel Code. The two are technically identical for Monel forged fittings and flanges; ASME SB564 is typically referenced for boiler and pressure-vessel code compliance.
Do you supply Mill Test Certificates with Monel flanges?
Yes. Every Monel flange from Kalpataru Piping is supplied with an EN10204 Type 3.1 Mill Test Certificate as standard. Type 3.2 third-party witnessed certification and additional QAP or radiography documentation can be arranged on request.
What is the typical lead time for Monel flanges?
Standard sizes in Monel 400 and Monel K500 are typically available ex-stock or within a short lead time; custom sizes, pressure classes, or Type 3.2 certification requirements may extend delivery. Contact our sales team with your specification for an accurate lead-time estimate.
What is the difference between a Monel Slip-On Flange and a Monel Weld Neck Flange?
A slip-on flange slides over the pipe end and is fillet-welded on both sides, making it easier and faster to install at lower pressure ratings. A weld neck flange has a tapered hub that is butt-welded to the pipe, giving superior stress distribution and making it the preferred choice for high-pressure, high-temperature, and cyclic-load services.
