PLBS Bulkhead Elbow Union

Stainless steel Bulkhead Elbow Union are made of 316L stainless steel for corrosion resistance, use FKM/Viton sealing material for chemical resistance. these stainless steel bulkhead elbow union fittings connect a tube through a panel. it has tube connection on one end, bulkhead connection on the other elbow end. Tube outer diamteters metric size  are available in 4mm to 16mm, and inch size are available in 1/8'' to 1/2''. Ruisen stainless steel fittings are Food Grade,Comply to FDA Standard.

Specifications:

Application:

Stainless steel push in connect fittings are suitable for all those applications where brass nickel-plated and acetal fittings are banned.

Stainless Steel fittings are widely used in petrochemical industry, food and medical machinery, lithium battery equipment, coffee machines, aerospace, automatic packaging, robots, water purifiers, industrial equipment, semiconductors.

国标夹紧连接原理：

&&1不锈钢快插夹持管的端部有环形U形槽，内有O形圈。安装时，将不锈钢管插入管件内，用专用卡箍在吊杆端部夹紧，以减小U型槽的内径。薄壁不锈钢管的承插部分与管件可同时收缩夹紧成六角形，以满足连接强度和密封要求。特别注意：夹紧管中的O形圈在压缩后仍有弹性。它有弹性保持力。能自动补偿早晚季节变化引起的热膨胀和冷收缩，保证管道安全

二。压环原理：在管子上用薄橡胶套，插入管件内，用工具挤压一次。由于橡胶皮太薄，不锈钢快塞直内六角挤压后，橡胶皮过度压缩，导致橡胶皮失去弹性，受热膨胀和冷收缩的影响，漏水隐患大大增加。

三。关键技术：1。固溶处理：加热和冷却处理，消除变形引起的硬化和内应力，防止受压工件的应力腐蚀；焊接过程中，焊缝的柱状晶变为等轴晶。热影响区中的碳化物溶解在奥氏体中，以防止晶间腐蚀和应力。对于铸件来说，可以避免大量的高温铁素体，并且可以防止奥氏体不锈钢的性能受到不利影响。

2.钝化处理是防止不锈钢腐蚀的关键措施之一。其作用是将货物放置在管道和管件的内外壁上。填料能使不锈钢产生致密、坚硬的钝化蜡。钝化膜的存在是防止不锈钢腐蚀的根本原因。
