Our dedicated sampling cylinders feature: electropolished internal surfaces (Ra less than 0.4 micron) to prevent sample adsorption and contamination; dual-end valve configurations with needle valves or ball valves for precise filling and dispensing; working pressures up to 5000 psi (345 bar); and material traceability with full 3.1 mill test certificates compliant with <strong>EN 10204<\/strong> e <strong>ASME IX<\/strong> standards.\n\nSampling Cylinder Product Range\n\n<strong>Piston Cylinders:<\/strong> Floating piston design maintains constant pressure during transport. Ideal for volatile liquids (LPG, condensate, light crudes) and dissolved gas samples. Available in 250ml to 1000ml capacities with PTFE or Viton floating pistons.\n<strong>Constant Pressure Cylinders:<\/strong> Spring-loaded or nitrogen-blanketed design keeps samples at constant pressure from field to lab. Prevents phase changes and loss of light ends during extended transport periods.\n<strong>Standard Sample Cylinders:<\/strong> Fixed-volume design for stable liquid sampling. 316SS construction with DOT\/TC approved options for transport compliance.\n<strong>Custom Configurations:<\/strong> Non-standard materials (Monel, Inconel, Hastelloy), special volumes, multi-compartment designs, and integrated heating\/cooling jackets available upon request.\n\n\nQuality Assurance - Six-Step Process\nEvery cylinder undergoes: (1) raw material verification with mill certificates, (2) precision CNC machining with dimensional inspection, (3) hydrostatic testing at 1.5x rated pressure, (4) helium leak testing below 1x10^-9 mbar.L\/s, (5) electropolishing and passivation per ASTM B912, and (6) final cleaning and packaging in nitrogen-purged containers.\n\nView our complete <a href=\"\/pt\/categoria-produto\/cilindro-de-aco\/\">sampling cylinder catalog<\/a> with detailed specifications, CAD drawings, and pricing information.","link":"https:\/\/wanantec.com\/pt\/categoria-produto\/category-steel-cylinder\/","name":"Cilindro de a\u00e7o","slug":"category-steel-cylinder","taxonomy":"product_cat","parent":0,"meta":[],"acf":[],"_links":{"self":[{"href":"https:\/\/wanantec.com\/pt\/wp-json\/wp\/v2\/product_cat\/137","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/wanantec.com\/pt\/wp-json\/wp\/v2\/product_cat"}],"about":[{"href":"https:\/\/wanantec.com\/pt\/wp-json\/wp\/v2\/taxonomies\/product_cat"}],"wp:post_type":[{"href":"https:\/\/wanantec.com\/pt\/wp-json\/wp\/v2\/product?product_cat=137"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
